The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government agency within Public Works and Government Services Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as national standards, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue, which is published annually and is available without charge upon request. An electronic version, ECAT, is also available. More information is available about CGSB products and services at our Web site — http://www.pwgsc.gc.ca/cgsb. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Users of this standard are expressly advised that determination of the validity of any such patent rights are entirely their own responsibility.

The STANDARDS COUNCIL OF CANADA is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international co-operation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard that is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with the: Standards Council of Canada 270 Albert Street Suite 200 Ottawa, Ontario K1P 6N7

CAN/CGSB-48.9712-2000

National Standard of Canada in accordance with ISO 9712:1999, MOD Non-destructive testing — Qualification and certification of personnel

The employer is responsible: A certification body that issues a certificate in non-destructive testing (NDT) under CAN/CGSB-48.9712-2000 testifies to the qualification of an individual but does not give any authorization to operate (give permission to work). The employer is responsible for authorizing Canadian General Standards Board (CGSB)-certified NDT personnel to operate, based on the individual’s suitability for a specific job(s). The employer shall be fully responsible for all that concerns the authorization to operate, including the validity of the results of NDT operations. The employer is responsible to ensure that employees annually meet the visual acuity requirements and for verification of employee continuity of NDT work in the application of the NDT method(s) without significant interruption. CGSB-certified personnel are issued certification in an NDT method/sector through a process of qualification based upon meeting the minimum requirements under this standard for knowledge, skill, training, experience and the ability to pass examinations — all of a general-knowledge nature. However, the work of CGSB-certified personnel may require a special knowledge of NDT as applied by his employer (company) to company or product specific tasks that are beyond the scope of the CGSB general-knowledge certification. Since “the employer is responsible,” it is recommended that the employers provide additional training, experience and examination (see 3.10) in their company- or product-specific tasks. Such tasks may include performing, specifying, reviewing, monitoring, supervising, and evaluating NDT work in a manner or of a nature that is unique to the company. Special knowledge may include company-specific methods, techniques, equipment, procedures, specifications, codes, etc. for which CGSB-certified personnel have responsibilities within the scope of their employment. Annex F provides guidance to the employers for the preparation of examinations to qualify their personnel for companyor product-specific tasks. Note that these examinations are outside the scope of this standard. Qualification by the employer is neither qualification nor certification by a certification body and does not meet the requirements nor fulfil the provisions of this standard. Employer qualification of NDT personnel enhances but does not replace CGSB certification. The employee is responsible: Individuals certified to this standard shall recognize the precepts of personal integrity and professional competence as fundamental principles. CGSB-certified personnel are held responsible by the certification body to comply with the requirements of the “Code of ethics for NDT personnel” in Annex G. The failure of a certified individual to comply with one or more of these requirements constitutes just cause for de-certification by the certification body.

CAN/CGSB-48.9712-2000

National foreword This Canadian National Standard CAN/CGSB-48.9712-2000 is a modified adoption of the International Standard ISO 9712:1999, Non-destructive testing — Qualification and certification of personnel. CAN/CGSB-48.9712-2000 was prepared and approved by the CGSB Committee on Nondestructive Testing and Certification of Personnel (48/2). CAN/CGSB-48.9712-2000 was prepared in 1999 to harmonize, as much as possible, with the provisions of International Standard ISO 9712:1999, Non-destructive testing — Qualification and certification of personnel. This standard replaces CAN/CGSB-48.9712-95, Qualification and Certification of Nondestructive Testing Personnel. Regulatory and code-writing bodies referencing CAN/CGSB-48.9712-95 should update their documents to reflect this change. It is also the intention that the Canadian National NDT Standard harmonizes with the European NDT Standard EN 473, Qualification and certification of NDT personnel — General Principles, and extensive reference to the latest edition, EN 473:2000, will be found in the text. Full adoption of ISO 9712:1999 is intended within the five-year period that ISO allows for compliance. Certain aspects of this International Standard are not presently acceptable to Canada because of fundamental climatic, geographical and technical problems — legitimate reasons for national deviations recognized in the Agreement on Technical Barriers to Trade of the World Trade Organization (WTO/TBT Agreement), which Canada signed in 1994. This Canadian National Standard has been reproduced from and reflects the format and content of ISO 9712:1999. In accordance with ISO/IEC Guide 21:1999, Adoption of International Standards as regional or national standards, Canadian deviations from the ISO 9712:1999 immediately follow the clause, figure or table. to which they refer. Each “national deviation” appears in a double-lined box along with a “national explanation” of the reasons for the deviation and the intended date for full compliance with ISO 9712:1999 if applicable. Where there are national deviations, Canada has looked to EN 473:2000 for guidance and appropriate wording. A double-lined box may also contain a “national explanatory note,” which provides additional information on the national adoption of ISO 9712:1999. In addition, whenever the words “International Standard” appear in the text, they should be understood as meaning “National Standard of Canada.” A summary of some of the differences between Canadian National Standard CAN/CGSB-48.9712-2000 and the International Standard ISO 9712:1999 follows: — deleted, expanded and additional definitions to clarify the meaning of the text; — more examination questions. Unlike the narrow industrial sectors of ISO 9712, Canada’s certification is in a broad sector termed EMC (Engineering Materials and Components), which includes welds, forgings and castings. Also, the number of questions permits commonality between Canada and the U.S.A.; — additional examination attempts for initial certification and for recertification at levels 1, 2 and 3.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 9712 was prepared by Technical Committee ISO/TC 135, Non-destructive testing Subcommittee SC 7, Personnel qualification. This second edition cancels and replaces the first edition (ISO 9712:1992) which has been technically revised. Annexes A to C of this International Standard are for information only.

CAN/CGSB-48.9712-2000

Non-destructive testing — Qualification and certification of personnel Introduction Since the effectiveness of any application of non-destructive testing depends upon the capabilities of the persons who perform or who are responsible for the test, a procedure was developed to provide a means for evaluating and documenting the competence of personnel whose duties require the appropriate theoretical and practical knowledge of the non-destructive tests that they perform, specify, supervise, monitor or evaluate. An added incentive stems from the world-wide comparability of a wide range of industrial applications requiring common non-destructive testing approaches. Any certification body adopting this International Standard shall comply with level 3 requirements for qualification and certification, but is permitted a transition period of up to five years to implement levels 1 and 2. The aim is to permit the starting of the system in a country that has no third party certification. It is also applicable when an independent certification body applies the certification scheme to a new NDT method or when a new industrial sector is created. NOTE Wherever gender specific words such as “his,” “her,” “he” or “she” appear in this International Standard the other gender is also applicable.

National explanatory note: Canada’s previous standard CAN/CGSB-48.9712-95 contained two options for qualifying and certifying NDT personnel: Option A (non-ISO) almost fully complied with ISO 9712:1992 but retained some features of past Canadian standards, which were still desired by the Canadian industry. Option B (ISO) fully complied with ISO 9712:1992. CAN/CGSB-48.9712-2000 reflects Canada’s desire to move toward international harmonization while respecting Canadian geography, low population density, climate, traditions and industrial environment. It is Canada’s desire to have one National NDT Standard (no options) that complies with the International Standard ISO 9712. With this National Standard, CAN/CGSB-48.9712-2000, Canada formally adopts ISO 9712:1999 with some minor modifications. The availability and choice between option A (non-ISO) and option B (ISO) has ceased; all certified personnel must meet the requirements of this National Standard. Recertification Candidates for recertification can no longer switch from Option B to Option A, but must now pass the recertification examination(s). This standard provides for retakes of failed recertification examinations (see 10.3) during the five-year transition period (before January 1, 2005) allowed by ISO 9712:1999. Renewal Once individuals are certified in Canada, they hold their initial certificate forever, but their certification status can be “active” or “inactive.” An inactive status means that the individual no longer holds a valid certification. Certification can be maintained active by timely renewal. Up to three and a half years after the renewal deadline, certification may be reinstated as active by submitting a renewal application accompanied by documented proof of work experience without significant interruption (see 3.25) and an employer affidavit attesting to continuing NDT experience. Without such proof and an affidavit, or if the renewal application is more than three and a half years after the deadline, individuals can change their status from inactive to active by successful recertification or, failing recertification, by the successful completion of the initial certification process.

Non-destructive testing — Qualification and certification of personnel 1 Scope 1.1 This International Standard establishes a system for the qualification and certification, by a certification body, of personnel to perform industrial non-destructive testing (NDT) using any of the following methods: a) eddy current testing; b) liquid penetrant testing; c) magnetic particle testing; d) radiographic testing; e) ultrasonic testing. 1.2 The system described in this International Standard may also apply to visual inspection (VT), leak testing (LT), neutron radiography (NT), acoustic emission (AT) and other NDT methods where independent certification programmes exist. 1.3 Where latitude is provided in the criteria within this International Standard, the certification body shall have the final decision in determining specific requirements. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. EN 45013:1989, General criteria for certification bodies operating certification of personnel. 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 authorized qualifying body competent organization, independent of the employer or responsible agency, approved by the certification body to prepare and administer examinations to qualify NDT personnel

CAN/CGSB-48.9712-2000

3.2 candidate individual seeking certification in accordance with this International Standard National deviation: Replace the text of 3.2 with “individual who is registered with a certification body as seeking qualification and subsequent certification to this standard. The individual works or has worked under the supervision of suitably qualified personnel while gaining appropriate experience.” National explanation: A candidate cannot be self-declared but must be registered with the certification body. Otherwise the certification body will have no knowledge of his existence, including who he is, how to contact him, or what stage he is at in the qualification process leading to certification to this standard.

3.3 certificate written testimony of qualification National deviation: Add “An official, written legal document issued by the certification body, bearing its seal and signed by its officer(s), serving as evidence of the individual’s level of competency in NDT and his fulfillment of all of the qualification requirements of this standard” National explanation: The original definition needs elaboration concerning purpose, description and responsibility.

3.4 certification body agency that administers procedures for certification of NDT personnel in accordance with the requirements of this International Standard National explanatory note: In Canada, the certification body is also called the National Certifying Agency.

3.5 certification procedures leading to a written testimony of the qualification of an individual’s level of competence in a given NDT method and industrial sector National deviation: Replace the text of 3.5 with “procedures leading to a written testimony, issued by the certification body, of the qualification of an individual’s level of competence in a given NDT method and industrial sector” National explanation: According to ISO/IEC Guide 2:1996, Standardization and related activities — General vocabulary, “certification is a procedure by which a third party gives written assurance that a product, process or service conforms to specified requirements.” Under this National NDT Standard, the certification body is the third party conducting the certification procedure and issuing written assurance (certificate) that an individual conforms to the specified qualification requirements (e.g. knowledge, training, experience, skill, examinations, eyesight and code of ethics) of this standard.

2

CAN/CGSB-48.9712-2000

National deviation: Add: 3.5A certified status granted by the certification body to an individual holding a certificate, issued by the certification body, attesting to the holder’s level of competence, in a given NDT method and industrial sector 3.5B certify action of the certification body to officially declare in writing, by means of issuing a certificate, the level of competence of an individual, in a given NDT method and industrial sector. Competence is determined through a process of qualification, controlled and conducted by the certification body, that measures the knowledge, training, experience, skill, etc. of the individual in accordance with the specified qualification requirements of this standard. National explanation: These additional definitions complete the definitions pertaining to certification in 3.3, 3.4 and 3.5. See also 3.24, 3.24A and 3.24B. NOTE In 6.2.3 f) and 9.1, the certification body controls the issue of certificates.

3.6 employer or responsible agency organization for which the candidate works on a regular basis National explanatory note: According to 6.5.4, the candidate may be self-employed.

3.7 examination, basic one of the level 3 qualification examinations which assesses the knowledge of: — the materials science and processes technology, — this qualification and certification system and — the basic principles of NDT methods as required for level 2 3.8 examination centre centre approved by the certification body, either directly or through the authorized qualifying body, where qualification examinations will be carried out National explanatory note: An examination centre may be located on the employer’s premises, provided that examination supervision (invigilation) is assured by an individual authorized by the certification body.

3.9 examination, general written level 1 or level 2 examination concerned with the principles of an NDT method 3.10 examination, job-specific any additional examination concerned with the application of an NDT method to a specialized product not commonly involved in a particular industrial sector NOTE This examination is outside the scope of this International Standard.

CAN/CGSB-48.9712-2000

National explanatory note: Annex F provides guidance to employers concerning the preparation of examinations that can be used to assess their personnel for company- or product-specific tasks.

3.11 examination, main method one of the level 3 qualification examinations, which assesses the general and specific knowledge of the level 3 candidate in the method for which certification is sought, and the ability to write NDT procedures 3.12 examination, practical examination to assess the candidate’s ability to perform the NDT method 3.13 examination, qualification examination administered by a certification body or by an authorized qualifying body, which assesses the knowledge and capabilities of the candidate 3.14 examination, specific written examination concerned with the application of an NDT method in a particular industrial sector or sectors, which includes knowledge of the product and related codes, standards, specifications and acceptance criteria 3.15 examiner person certified to level 3 in the method he is to examine, and authorized by the certification body to conduct and/or grade NDT qualification examinations NOTE No level 3 person shall be the only examiner for any candidate he has personally trained for that examination.

3.16 experience period during which the candidate performed the specific NDT method under qualified supervision, including personal application of the NDT method to materials, parts or structures National explanatory note: Practical tests performed during training courses are not considered as experience. Note that experience may be acquired either before or after success in the qualification examination (7.2A).

3.17 industrial sector particular area in industry or technology where specialized NDT practices are utilized requiring specific skill, knowledge, equipment or training to achieve satisfactory performance NOTE An industrial sector may be interpreted to mean a product (welds, castings, etc.) or an industry (aerospace, steel, etc.), see also annex A

4

CAN/CGSB-48.9712-2000

National deviation: Add: 3.17A invigilator, authorized person authorized by the certification body to supervise examinations National explanation: Invigilator is not defined in ISO 9712:1999. Subclause 3.15 defines an examiner as a level 3 who can conduct and/or grade examinations. Often, the invigilation of NDT examinations does not require the presence of an NDT expert. The individual administering the examination (the invigilator) needs to verify the appointment, inform the candidate of what is required, explain the rules, distribute examination forms, provide vigilance during the examination, control the time, collect the completed examination forms, and send the witnessed examinations and forms to the certification body for grading. In Canada, the certification body retains the right to authorize persons to invigilate the NDT examinations. This is in accordance with 8.3.2 and 8.3.4.

3.18 NDT instruction written description of the precise steps to be followed in testing to an established NDT procedure, standard, code or specification 3.19 NDT method application of a physical principle in non-destructive testing (e.g. ultrasonic testing) 3.20 NDT procedure orderly sequence of steps describing where, how and in which sequence an NDT method should be applied to a product 3.21 NDT technique specific way of utilizing an NDT method (e.g. immersion ultrasonic testing) 3.22 NDT training process of instruction in theory and practice in the NDT method in which certification is sought, which takes the form of training courses to an approved syllabus, but shall not include the use of specimens used in practical examinations National explanatory note: In Canada, the certification body has established approved training syllabi for each NDT method and level. See 7.1.1 and 7.1.2 and annexes B, D and E for more information on training.

3.23 operating authorization permission to work, issued by the employer or responsible agency and based on the individual’s suitability for a specific job 3.24 qualification demonstration of physical attributes, knowledge, skill, training and experience required to properly perform NDT tasks

CAN/CGSB-48.9712-2000

National deviation: Replace the text in 3.24 with “demonstration or evidence of a set of abilities, such as knowledge, training, experience, skill and eyesight, in compliance with the specified requirements of this standard. These abilities must be demonstrated before the certification body considers an individual competent to perform specific functions in the NDT profession. Qualification is a process that measures the individual’s level of competence in NDT. It is controlled solely by the certification body and upon completion leads directly to certification of the individual by the certification body.” National explanation: The original definition needs elaboration regarding purpose, description and responsibility. This definition is in accordance with ISO 8402:1994, Quality management and quality assurance — Vocabulary, which defines qualification as a “process of demonstrating whether an entity (product, process, organization or person) is capable of fulfilling specified requirements.”

National deviation: Add: 3.24A qualified having demonstrated the necessary qualifications (abilities, knowledge, skills, training, experience, etc.) in accordance with the requirements of this standard, the individual is considered competent by the certification body to perform specific functions in the NDT profession 3.24B qualify act(s) of an individual to demonstrate to the certification body competency in NDT by fulfilling the qualification requirements (abilities, knowledge, skills, training, experience, etc.) of this standard National explanation: These definitions are needed to complete those pertaining to qualification in 3.24.

National explanatory note: This standard carries the title “Non-destructive testing — Qualification and certification of personnel.” Qualification is a process of demonstrating abilities against specific requirements of this standard. For example, individuals provide proof of training, experience and eyesight, and demonstrate their ability by passing written and practical examinations. “Certification is a procedure administered by a third party (a body that is recognized as being independent of the parties involved, i.e. an organization that is not involved in the individual’s training or employment). After an individual has successfully fulfilled all qualification requirements, the certification body issues a certificate testifying to the individual’s level of competence.” (Reference: ISO/IEC Guide 2:1996) The certification body is the only entity that is aware of and documents the progress of an individual through the various stages of qualification; thus it is the only entity that can declare that an individual fulfils one or more requirements of the standard. When the qualification process is completed by the certification body (all requirements of qualification fulfilled), the certification body will declare the individual certified by publishing the individual’s name and issuing a certificate (a written testimony of qualification) and wallet-card.

3.25 significant interruption absence or a change of activity which prevents the certified individual from practising the duties corresponding to his level in the method and the industrial sector(s) for which he is certified, for a continuous period exceeding one year

6

CAN/CGSB-48.9712-2000

3.26 supervision act of directing the application of NDT performed by other NDT personnel, which includes the control of actions involved in the preparation of the test, performance of the test and reporting of the results National deviation: Add: 3.26A supervision, qualified to gain experience in accordance with 3.16, the candidate must be supervised by NDT personnel certified to this National Standard or by non-certified personnel who, in the opinion of the certification body, possess the knowledge, skill, training and experience required to properly perform such supervision National explanation: This definition explains “qualified supervision,” which is referred to in 3.16.

3.27 test specimen sample used in practical examinations NOTE Samples should be representative of products typically tested in the applicable industrial sector and may include more than one area or volume to be tested.

3.28 trainee individual who works under the supervision of certified personnel but who does not conduct any tests independently, does not interpret test results and does not write reports on test results NOTE This individual may be registered as being in the process of gaining appropriate experience to establish eligibility for qualification to level 1 or for direct access to level2.

National explanatory note: Trainees are outside the scope of this standard. They are not recognized, classified, certified or qualified in accordance with the requirements of this standard, and have no competence under this standard. This in accordance with EN 473:2000, which has no definition or classification for trainees.

4 Abbreviations The following abbreviations shall be used to identify the five Non-destructive testing (NDT) methods covered by this International Standard: — eddy current testing ET — liquid penetrant testing PT — magnetic particle testing MT — radiographic testing RT — ultrasonic testing UT

5 Levels of competence (NDT levels) 5.1 Classification An individual certified in accordance with this International Standard shall be classified in one of the following three levels, whereas one who has not yet attained certification may be classified as a trainee. National deviation: Replace the text in 5.1 with “An individual certified in accordance with this National Standard shall be classified in one of the following three levels.” National explanation: This is in accordance with EN 473:2000, which does not recognize a trainee either by definition or by assigning a classification. Canada recognizes only three levels of competence, and those are for certified individuals classified as level 1, level 2 and level 3.

5.2 NDT level 1 5.2.1 An individual certified to NDT level 1 is qualified to carry out NDT operations in accordance with written instructions and under the supervision of level 2 or level 3 personnel. He shall be able to: a) set up the equipment; b) perform the tests; c) record and classify the results in accordance with documented criteria; d) report on the results. 5.2.2 An individual certified to level 1 shall not be responsible for the choice of the test method or technique to be used. 5.3 NDT level 2 An individual certified to NDT level 2 is qualified to perform and direct non-destructive testing in accordance with established or recognized procedures. This may include: a) defining the limitations of application of the test method for which the level 2 individual is qualified; b) translating NDT codes, standards, specifications and procedures into practical testing instructions adapted to the actual working conditions; c) setting up and verifying equipment settings; d) performing and supervising tests; e) interpreting and evaluating results according to applicable codes, standards and specifications; f) preparing NDT instructions; g) carrying out or supervising all level 1 duties; h) training or guiding personnel below level 2; i) organizing and reporting results of non-destructive tests.

CAN/CGSB-48.9712-2000

National deviation: Replace the text of h) with “training or guiding personnel at or below level 2;” Add: j) selecting the NDT technique for the test method to be used. National explanation: Item h) is altered to be in accordance with EN 473:2000 to permit a level 2 to train or guide personnel at the same level. While not listed in 5.3, ISO 9712:1999 states in Table 6, Item 2 a), “for level 2, selection of the techniques and determination of the operating conditions.” Thus, there is a conflict within the ISO Standard. Both ISO 9712:1992 and EN 473:2000 allow a level 2 to select the technique. Canada has always permitted a level 2 to select the NDT technique and will continue to allow it.

5.4 NDT level 3 5.4.1 An individual certified to NDT level 3 may be authorized to direct any operation in the NDT method(s) for which he is certified. This may include: National deviation: Replace the text of 5.4.1 with “An individual certified to NDT level 3 is qualified to direct any operation in the NDT method(s) for which he is certified. This may include:” National explanation: This editorial change makes the wording in 5.4.1 consistent with that in 5.2.1 and 5.3. In ISO 9712:1992, these clauses read “may be authorized to.” Anticipating a future editorial correction, Canada has harmonized the wording of 5.4.1, 5.2.1 and 5.3.

a) assuming full responsibility for an NDT facility and staff; b) establishing and validating techniques and procedures; c) interpreting codes, standards, specifications and procedures; d) designating the particular test methods, techniques and procedures to be used for specific NDT work; e) interpreting and evaluating results in terms of existing codes, standards and specifications; f) managing qualification examinations, if authorized for this task by the certification body; g) carrying out or supervising all level 1 and level 2 duties. 5.4.2 An individual certified to level 3 shall have: a) sufficient practical background in applicable materials, fabrication and product technology in order to be able to select methods and establish techniques and to assist in establishing acceptance criteria where none is otherwise available; b) a general familiarity with other NDT methods; c) the ability to train or guide personnel below level 3. 6 Responsibilities 6.1 General The certification activity shall be administered by a certification body, with the assistance, where necessary, of authorized qualifying bodies. It includes all procedures adopted to demonstrate the qualification of an individual to carry out tasks in a specific NDT method and leads to certification of his competence. 6.2 Certification body 6.2.1 A certification body shall conform with the requirements of EN 45013. It should be a non-profit organization which has no direct involvement in training of NDT personnel and it should be recognized by the NDT community or the ISO member body of the country concerned. CAN/CGSB-48.9712-2000

6.2.2 A certification body shall be supported by a committee composed of representatives of NDT societies, committees, users, suppliers, government departments and other interested parties as appropriate. This committee shall be responsible for setting and maintaining the technical standards of examination. Its members shall be qualified for the tasks by an appropriate combination of NDT certification and/or experience. At least 50 % of its members shall hold a valid level 3 certification. 6.2.3 A certification body: a) shall initiate, maintain and promote the certification scheme as specified in this International Standard; b) shall administer the procedures and operations for certification in accordance with a documented procedure, meeting the minimum requirements of this International Standard and a stringent code of ethics, including sanctions, which shall apply to committee members and certificate holders; c) may delegate, under its direct responsibility, the detailed administration of the certification procedure to other organizations acting as qualifying bodies; d) shall take the ultimate responsibility for the certification scheme, including technical and administrative requirements; e) shall approve, either directly or through an authorized qualifying body, properly staffed and equipped examination centres which it shall monitor on a periodic basis; f) shall keep all appropriate records and issue, or delegate the issuing of, certificates; g) shall maintain a collection of current examination questions. For each multiple-choice question this data bank shall indicate the correct answer. For other questions this data bank shall include a model answer. It is desirable that answers include a reference that validates the answer; h) shall, when creating a multi-sector, define precisely the chosen combination of the sectors which constitute the multisector. Guidance on the creation of industrial sectors is given in annex A. 6.3 Authorized qualifying bodies An authorized qualifying body shall, where established, be approved by the certification body and shall, with the approval of the certification body: a) apply a documented quality procedure; b) establish and monitor examination centres; c) prepare and supervise the qualification examinations; d) maintain appropriate qualification and examination records according to the requirements of the certification body. 6.4 Examination centres 6.4.1 Examination centres shall be established or approved by the certification body or through authorized qualifying bodies and shall, as a minimum: a) have adequate qualified staff, premises and equipment to ensure satisfactory qualification examinations for the levels, methods and industrial sectors concerned; b) use only those documents and examination questionnaires established or approved by the certification body; c) use only specimens approved by the certification body for the practical examinations conducted at that centre; d) apply a documented quality procedure. National deviation: Add to 6.4.1 d) “approved by the certification body.” National explanation: For a certification body to comply with EN 45013, the quality procedure of an examination centre must comply with the quality procedure of the certification body. This is in accordance with EN 473:2000.

6.4.2 When more than one authorized examination centre exists, each shall have test specimens of comparable test difficulty containing similar discontinuities. Under no circumstances shall test specimens be used for training purposes. 10

CAN/CGSB-48.9712-2000

6.5 Employer or responsible agency 6.5.1 The employer or responsible agency shall introduce the candidate to the certification body or the authorized qualifying body and document the validity of the personal information provided. The documentation shall include the declaration of education, training and experience needed to establish the eligibility of the candidate. The employer or responsible agency shall not be directly involved in the certification procedure itself. 6.5.2 The employer or responsible agency shall be fully responsible for all that concerns the authorization to operate, including the validity of the results of NDT operations. 6.5.3 The employer or the responsible agency shall ensure that employees annually meet the visual acuity requirements of 7.2.3 (see note in 9.2). National deviation: Add: 6.5.3A The employer or responsible agency shall verify that the employee has maintained his NDT activity and practised the duties corresponding to his level in the NDT method and the industrial sector(s) for which he is certified without significant interruption. National explanation: Subclause 6.5.1 appears to cover initial certification. Subclauses 6.5.2, 6.5.3 and 7.2.3 cover other responsibilities beyond initial certification such as authorization to operate and annual vision tests. However, the employer(s) is also responsible for verifying that certified employees have maintained their NDT activity and practised the duties corresponding to the level in the NDT method and the industrial sector(s) in which they are certified. Subclause 6.5.3A is added to cover this omission. This is in accordance with EN 473:2000.

6.5.4 If the individual is self-employed, or presents himself alone, he shall assume all responsibilities specified for the employer or responsible agency. 7 Eligibility 7.1 Eligibility for examination To be eligible for examination, the candidate shall fulfil the minimum NDT training requirements which are specified in this clause. 7.1.1 NDT training — level 1 and level 2 The candidate shall provide evidence acceptable to the certification body of completion of a course of NDT training in the method and level for which certification is sought. Training providers should issue documentary proof of completion of training. National deviation: Delete the last sentence in 7.1.1 and replace with “Training providers must issue documentary proof of satisfactory completion of training. Each NDT training course must follow the curriculum prescribed by the certification body (see Annex E). The certification body decides on the acceptability of NDT training courses and of course instructors (see Annex D).” National explanation: The certification body requires documentary proof that training was satisfactorily completed. This requirement is in accordance with EN 473:2000. In Canada, candidates may obtain training as follows: candidates may attend formal courses offered in the larger population centres; companies may ask course providers to provide on-site training; with prior approval by the certification body, companies may conduct their own training courses; candidates may follow a program of self-training or correspondence courses because of the remoteness of their location or other reasons. Because of this diversity, the certification body will retain control over training, including the syllabus and the instructor. See annexes D and E for more information.

Information in annex B may be used to guide development of training and education syllabi. CAN/CGSB-48.9712-2000

NOTE 1 Training hours include both practical and theory courses. NOTE 2 Direct access to level 2 implies the total hours for level 1 and level 2.

7.1.2 Training — level 3 Depending on the scientific and technical potential of a candidate for level 3 certification, preparation for qualification may be done in different ways: e.g. by attending training courses, conferences or seminars (such as those organized by industrial or independent associations), studying books, periodicals and other sources of relevant information. However the candidate has prepared, he shall provide documentary evidence of training acceptable to the certification body. Information in annex B may be used to guide development of training and education syllabi. 7.2 Eligibility for certification To be eligible for certification, the candidate shall have passed the qualification examination and shall fulfil the minimum requirements specified in this clause. National deviation: Add: 7.2A Industrial NDT experience Industrial NDT experience may be acquired either before or after success in the qualification examination. If experience is sought after successful examination, the results of the examination shall remain valid for two years. National explanation: Subclauses 7.1, 7.1.1, 7.1.2, 7.2, 7.2.1 and 7.2.2 differ significantly from ISO 9712:1992, which required candidates to have experience before being eligible to take the qualification examination. Now, experience can be gained after passing the qualification examination. However, 7.2 does not indicate how long candidates have to gain this experience. Subclause 7.2A (from EN 473:2000) is needed to define the time limit between passing the examination and gaining the required experience. The certification body shall issue letters of attestation to successful candidates, indicating that they have passed the qualification examination and need only to meet the experience requirement to be certified.

12

CAN/CGSB-48.9712-2000

7.2.1 NDT experience — level 1 and level 2 The minimum requirements for experience to be gained prior to certification shall be as specified in Table 2.

NOTE 1 Work experience in months is based on a nominal 40 h/week (175 h/month) or the legal week of work. Any individual working in excess of 40 h per week, may be credited with experience based on the total hours, but shall be required to produce documentary evidence of this experience. NOTE 2 For level 2 certification, the intent of this International Standard is that work experience consists of NDT work time as an individual certified to level 1. If the individual is being qualified directly to level 2, with no time at level 1, the experience shall consist of the sum of the times required for level 1 and level 2. NOTE 3 Credit for work experience may be gained simultaneously in two or more of the NDT methods covered by this International Standard, with the reduction of total required experience as follows: a) two testing methods — reduction of total required time by 25 %; b) three testing methods — reduction of total required time by 33 %; c) four or more testing methods — reduction of total time by 50 %. In all cases where a reduction is sought the candidate shall be required to show that, for each of the testing methods for which he seeks certification, he has at least half of the time required in this table.

7.2.2 NDT experience — level 3 Level 3 responsibilities require knowledge beyond the technical scope of any specific NDT method. This broad knowledge may be acquired through a variety of combinations of education, training and experience, which shall be documented and provided to the certification body. Table 3 details minimum experience related to formal education.

NOTE If a college or university degree is issued in non-destructive testing, the experience required for access to level 3 may be reduced by 50 %.

National deviation: Replace the NOTE in Table 3 with: NOTE 1 If the college or university degree is issued in non-destructive testing, the experience required for access to level 3 may be reduced by 50 %. NOTE 2 Credit for work experience may be gained simultaneously in two or more of the NDT methods covered by this National Standard, with the reduction of total required experience as follows: a) two testing methods – reduction of total required time by 25 %; b) three testing methods – reduction of total required time by 33 %; c) four or more testing methods – reduction of total time by 50 %. In all cases where a reduction is sought the candidate shall be required to show that, for each of the testing methods for which he seeks certification, he has at least half of the time required in this table.

National explanation: The new wording of Table 3 comes from Table 2 and is in accordance with EN 473:2000. Table 2 allows level 1 and 2 candidates a reduction in required experience for work experience gained simultaneously in two or more NDT methods. Canada believes that candidates for all levels of certification should be treated the same and extends this simultaneous experience provision to level 3 candidates.

7.2.3 Vision requirements — all levels The candidate shall provide documented evidence of satisfactory vision in accordance with the following requirements: National deviation: Replace the text in 7.2.3 with “The candidate shall provide documented evidence of satisfactory vision, as determined by an ophthalmologist, optometrist, physician, nurse or other medically recognized personnel, in accordance with the following requirements:” National explanation: Vision needs to be measured by medically recognized eye specialists or other qualified personnel.

a) near-vision acuity shall permit reading a minimum of Jaeger number 1 or Times Roman N4.5 or equivalent letters at not less than 30 cm with one or both eyes, either corrected or uncorrected;

14

CAN/CGSB-48.9712-2000

b) colour vision shall be such that the candidate can distinguish and differentiate contrast between the colours used in the NDT method concerned as specified by the employer. Subsequent to certification, the tests of visual acuity shall be carried out annually and be verified by the employer or the responsible agency (see 6.5.3). National deviation: Add: 7.2.4 Code of ethics Candidates requesting certification shall affirm their agreement to abide by the code of ethics in Annex G by signing a code of ethics declaration form. National explanation: In accordance with 6.2.3B, the certification body requires a code of ethics that applies to certified personnel.

8 Qualification examination The qualification examination shall cover a given NDT method as applied in one or more specific industrial sectors. 8.1 Examination content and grading for level 1 and level 2 8.1.1 General examination 8.1.1.1 The general examination shall include only questions selected from the certification body’s or authorized qualifying body’s collection of basic knowledge questions valid at the date of examination. The candidate shall be required, as a minimum, to give answers to the number of multiple choice questions shown in Table 4. 8.1.1.2 The time allowed to the candidates for completion of each examination shall be based upon the number and difficulty of the questions. The average time allowed shall be no less than one and no more than two minutes per multiple choice question. 8.1.1.3 Where not otherwise addressed by national regulations, there shall be an additional examination on radiation safety for the radiographic test method. 8.1.1.4 Examinations on the radiographic test method may include either X- or gamma-radiation, or both, depending upon the procedure of the certification body. National explanatory note: To be eligible for certification in the radiographic test method a candidate must successfully complete an examination in X-ray and gamma-ray-radiation safety. The candidate must obtain a minimum grade of 70 % in radiation safety. The grade(s) obtained in the radiation-safety examination(s) will not be used to calculate the composite grade referred to in 8.1.4.3.1 and 8.2.3.2.

8.1.3.6 The time allowed for the examination depends on the number of test specimens and of their complexity. The recommended maximum time allowed for each area or volume tested is: a) for level 1, three hours; b) for level 2, four hours. 8.1.3.7 Level 2 candidates shall draft at least one NDT Instruction suitable for level 1 personnel. 8.1.4 Grading of the level 1 and level 2 qualification examination 8.1.4.1 An examiner shall be responsible for the grading of the examinations. The general, specific and practical examinations shall be graded separately. 8.1.4.2 The examination grading should be based on items 1 to 4 in Table 6, with the recommended weighting in relation to the level. 8.1.4.3 The certification body shall implement the passing grade criteria in a consistent manner by using one of the following two methods: 8.1.4.3.1 Composite grade method To be eligible for certification the candidate shall obtain a minimum grade of 70 % in each examination and a minimum composite grade of 80 %. The composite grade N shall be calculated in accordance with the following formula: N = 0,25n g + 0,25n s + 0,50n p where n g is the grade for the general examination; n s is the grade for the specific examination; n p is the grade for the practical examination. National explanatory note: Canada has chosen to use the composite grade method. In accordance with 8.1.1.3 and 8.1.1.4 for the radiographic test method, the grades obtained in the radiation safety examinations will not be used for calculating composite grade.

8.1.4.3.2 Minimum grade method To be eligible for certification a candidate shall obtain a grade of at least 70 % in each of the written examinations and 80 % in the practical examination. National explanatory note: Canada has chosen not to use the minimum grade method.

National explanatory note: Candidates for radiography who did not previously satisfactorily complete the required X-ray and gamma-radiation safety examinations, as described in 8.1.1.3 and 8.1.1.4, must do so. The grades obtained in the radiation-safety examinations will not be used to calculate the composite grade.

8.3 Conduct of examinations 8.3.1 All examinations shall be conducted in examination centres established, approved and monitored by the certification body, either directly or through an authorized qualifying body. 8.3.2 At the examination, the candidate shall have in his possession valid proof of identity and an official notification of the examination, which shall be shown to the examiner or invigilator upon demand. 8.3.3 Any candidate who, during the course of the examination, does not abide by the examination rules or who perpetrates, or is an accessory to, fraudulent conduct shall be excluded from further participation. 8.3.4 Examinations shall be approved by an examiner. The examination shall be invigilated and evaluated by an examiner, or by one or more trained and authorized invigilators placed under the examiner’s responsibility. 8.3.5 An examiner shall be responsible for grading the examination in accordance with procedures established or approved by the certification body (see also 3.15). 8.3.6 With the approval of the certification body a candidate for a practical examination may use his own apparatus. The specimens used in training shall not be used as test specimens. 8.3.7 Level 3 examinations shall be set and graded by at least two examiners. 8.4 Re-examination 8.4.1 A candidate failing for reasons of unethical behaviour shall wait at least one year before reapplying. 8.4.2 A candidate who fails to obtain the pass grade required for certification may retake any of the examinations once, provided that the re-examination takes place no sooner than within 30 days, nor later than one year after the original examination. A certification body may use its discretion in allowing an earlier re-examination in the event that further training acceptable to the certification body is undertaken.

CAN/CGSB-48.9712-2000

National deviation: Replace “may retake any of the examinations once, provided that the re-examination takes place no sooner than within 30 days, nor later than one year after the original examination” with “may retake any of the examinations twice, provided that re-examinations take place not sooner than 30 days after a previous examination, nor later than two years after the original examination.” National explanation: Canada’s Engineering Materials and Components (EMC) sector covers several industrial sectors. The extent, duration and difficulty of Canada’s qualification examinations are greater than that for single-sector qualification because candidates must demonstrate a broad theoretical and practical knowledge of manufacturing processes and NDT of welds, casting and forgings. The Canadian qualification process takes longer, costs more and has higher failure rates than would be observed for single-sector certification under ISO 9712:1999. Canada has extensive experience with this, having implemented the “no retake“ provision of ISO 9712:1992 from 1996 through 1999. While ISO 9712:1999 increases the number of retakes to one, this is still insufficient to meet certification needs in Canada. Therefore, Canada will allow candidates for initial certification to retake any of the examinations twice. In addition, the candidate has two years to complete the qualification examination after the original examination. National explanatory note: For levels 1 and 2, the written examination consists of two separate examinations: general and specific. Similarly, a practical examination may consist of separate examination portions. A passing grade in any level 1 or 2 separate written examination or separate portion of a practical examination is valid for two years. For level 3 examinations, the same twoyear rule applies except for 8.2.1.2.

8.4.3 A candidate failing re-examination shall apply for and take the examination in accordance with the procedure established for new candidates. 8.5 Examination exemptions 8.5.1 A certified level 1 or level 2 individual changing from one industrial sector to another in the same NDT method shall be required to take only the specific examination and practical examination, for that method, concerning the new industrial sector. 8.5.2 A certified level 3 individual changing from one industrial sector to another in the same NDT method does not need to retake the basic examination nor the level 3 knowledge part (c1 of Table 8) of the main method examination. 9 Certification 9.1 Issuing of certificates A certification body, directly or through its authorized qualifying bodies, shall issue certificates and/or corresponding wallet cards only for personnel who meet all of the requirements for certification (see note in 9.2). 9.2 Requirements on certificates and wallet cards Certificates and/or corresponding wallet cards shall bear at least: a) the full name of the individual certified; b) the date of certification; c) the date upon which certification expires; d) the level of certification; e) reference to the certification body or to the authorized qualifying body; f) the NDT method(s); g) the industrial sector(s) concerned; h) a unique identification number;

i) the signature of the individual certified; j) a photograph of the individual certified in case of the wallet card; k) the cold seal of the certification body, cancelling the photograph to avoid falsification in the case of a wallet card; l) the signature of a representative of the certification body or the authorized qualifying body. NOTE By issuing the certificate and/or corresponding wallet card, the certification body or an authorized qualifying body attests to the qualification of the individual but does not give any operating authorization. There may be a special space on the certificate and/or wallet card for the signature of the employer or responsible agency authorizing the certificate holder to operate.

10 Certification validity and renewal 10.1 Validity The period of validity shall not exceed five years from the date of certification indicated on the certificate and/or wallet card. Certification shall be invalid: a) in any industrial sector other than that for which it was issued; b) at the discretion of the certification body after reviewing evidence of unethical behaviour; c) if the individual fails to meet the visual acuity requirements of 7.2.3; d) if a significant interruption takes place in the individual’s work in the method for which he is certified. 10.2 Renewal After the first period of validity, certification may be renewed by the certification body for a new period of similar duration, provided the certificate holder supplies documentary evidence of: a) satisfactorily meeting, during the preceding 12 months, the vision requirements of this International Standard and b) continued satisfactory work activity, relevant to the certification, without significant interruption. If criterion b) for renewal is not met, the individual shall follow the same rules as for recertification. National deviation: Add: c) reaffirmation of agreement to abide by the code of ethics in Annex G. National explanation: In accordance with 7.2.4, the certification body requires candidates renewing their certification to sign the code of ethics described in Annex G.

10.3 Recertification 10.3.1 Upon completion of each second period of validity, or at least every ten years, the certificate holder may be recertified by the certification body for a similar period, provided the individual meets the two criteria for renewal and passes a limited examination consisting of: National deviation: Replace “meets the two criteria for renewal” with “meets the criteria in 10.2 a) and c).” National explanation: According to 7.2.4, the certification body requires candidates for recertification to sign the code of ethics described in Annex G. Criteria b) was removed to avoid the endless loop in 10.2 b) and 10.3.1.

24

CAN/CGSB-48.9712-2000

a) Level 1 and level 2: a limited practical examination. National explanatory note: For levels 1 and 2, the recertification examination includes testing specimen(s) appropriate to the scope of certification and, for level 2, the production of a written instruction suitable for the use of level 1 personnel. The grade obtained is determined according to Table 6 and the composite grade method of 8.1.4.3.1. This process is in accordance with EN 473:2000.

b) Level 3: a written examination which includes: — at least 20 questions on the application of the test method in the industrial sector concerned and — at least 5 questions on the certification body’s qualification and certification system based on this International Standard. For recertification by examination in more than one method at the same time, the total number of questions may be reduced as indicated in Table 9. 10.3.2 If the individual fails to achieve a grade of at least 80 % in the recertification examination, he shall apply for new certification. National deviation: Replace the text in 10.3.2 with “A candidate who fails to achieve a grade of at least 80 % in the recertification examination may retake the recertification examination according to the following criteria and schedule: — In the five-year transition period (until January 1, 2005) allowed for levels 1 and 2 to comply with ISO 9712:1999, Canada will allow two (2) retakes of the recertification examination. This is extended to level 3 personnel. — After the transition period, the number of retakes shall be as designated in the then current ISO 9712 standard. — Retakes of recertification examinations shall be allowed within one year after the last examination. — The certification body will decide what portion of a failed recertification examination a candidate shall retake.” National explanation: Canada offers a broad-sector certification: Engineering Materials and Components (EMC). This is in contrast to ISO 9712:1999, which is directed at narrow industrial sectors. Examination in Canada’s broad-knowledge EMC sector, using an ISO “limited practical examination” or limited number of written questions, is prone to greater scatter in the results and consequently higher failure rates. For this reason, the ISO 9712:1999 policy of “no retakes” of failed recertification examinations is not presently acceptable to Canada. Also, since ISO 9712:1999 allows one retake for initial certification, it is logical that at least one retake should be permitted for recertification. Note that EN 473:2000 allows one retake of the recertification examinations. Canada believes that all levels of certified personnel should be treated the same; therefore, the five-year, two-retake provision is also extended to level 3 personnel. Annex H has more information.

10.3.3 As an alternative to the level 3 recertification examination specified in 10.3.1 b), the certification body may implement a structured credit system for recertification. For guidance purposes, examples of two such systems are given in annex C. National explanatory note: Canada has chosen not to allow recertification by a structured credit system. Therefore Annex C does not apply. Canada implements level 3 recertification by written examination(s) according to 10.3.1 b).

This file shall be kept for a period at least equal to the total of the initial period of validity plus the renewal period and shall contain: 1) application forms; 2) examination documents, including completed papers, descriptions of specimens, records, results of tests, written procedures and/or applicable NDT instructions, and grade sheets; 3) renewal documents, including evidence of physical condition and continuous activity; National deviation: Replace the text of 3) with “renewal and recertification documents, including evidence of visual acuity and continuous activity;” National explanation: Recertification documents should be kept as well as renewal documents. The only records of physical condition that are collected and stored are those concerning vision acuity.

Annex A (informative) Suggested industrial sectors When creating an industrial sector it is recommended that the certification body take into consideration the following reference list of industrial sectors. a) Castings (ferrous and non-ferrous materials). b) Forgings (all types of forgings: ferrous and non-ferrous materials). c) Welds (all types of welds, including soldering, for ferrous and non-ferrous materials). d) Tube and pipe (seamless, welded, ferrous and non-ferrous materials). e) Wrought products, except forgings (plates, bar, rods). f) Multi-sector: combination of sectors, including all or some products for a certain application (e.g., aerospace, in-service inspection) or certain types of materials (e.g., ferrous materials, non-ferrous materials). National deviation: Add: g) Engineering Materials and Components (EMC) h) Aviation National explanation: As of January 1999, Canada offered only “g” (EMC), aviation-radiography, and a few personnel were certified as “a/b and c” under pre-1979 Canadian standards. To meet the current demand and need of Canadian industry, an aviation sector is being developed.

Annex E (informative) Guides to NDT certification Guides to NDT certification for the five main NDT methods that were in CAN/CGSB-48.9712-95, are no longer printed as part of the National Standard. Guides do not belong in the National Standard because they are not actual provisions of the standard. The removal of the guides allows the certification body to make changes in the guides without requiring a redraft of the National Standard. Guides to NDT certification are available from the Canadian certification body. Guides to NDT certification are a valuable assistance in preparing for the NDT qualification examinations. Guides contain: a) training syllabi, approved by the certification body, for each NDT method and level of certification; b) complete breakdown of the subjects to study; c) titles of reference books to study from; d) typical examination questions; e) the form, process and what to expect in the examinations, including the practical examinations; f) detailed information for employers on how to create hands-on practical examinations for level 1; g) information for employers on setting up product-specific examinations.

Annex F (informative) Employer’s guide for preparing examinations for company- and product-specific tasks NOTE These examinations are outside the scope of this standard. This information is provided for guidance only.

F.1 Company and product-specific tasks, written examinations F.1.1 The examination should cover the equipment, calibration, operating and inspection procedures, NDT techniques and the specifications and codes used by the employer that candidates may encounter in their typical work activities or specific assignments. F.1.2 Twenty questions approved by an employer designate are to be answered. The employer designate should be qualified to at least level 2 in the applicable NDT method. F.2 Company and product-specific tasks, practical examinations F.2.1 Candidates should demonstrate to the satisfaction of the employer designate that they are able to follow procedures and instructions, set up and operate test equipment, and analyze the resultant information to the degree required. The employer designate should be qualified to at least one level higher than the candidate. F.2.2 In general, the candidate should test at least one selected specimen and analyze the results. At least ten different checkpoints requiring an understanding of test variables and the employer’s procedures should be included in this practical examination. F.2.3 The description of the specimen, the NDT procedure including check points, and the results of the examination should be documented. F.3 Evaluation of results To be qualified by the employer, personnel performing specialized nondestructive testing for specific products should obtain a mark of at least 70 % in the written and practical test and a combined average mark of at least 80 %. F.4 Maintenance of records The employer should maintain on file a record of the written and practical examination, a description of the test specimens and the marks obtained by the individuals receiving specific qualification. F.5 Vision requirements F.5.1 The employer should consider specifying the following vision requirements for personnel performing specialized nondestructive testing of specific products, if such physical attributes are required to perform the inspection reliably and safely. F.5.2 Distance vision acuity: Candidates shall demonstrate a minimum distance acuity of Snellen 6/12 (20/40) with their habitual correction. NOTE Distance acuity is normally required for on-the-job safety reasons.

F.5.3 Colour perception: Candidates shall demonstrate normal colour discrimination as shown by Ishihara or similar colour vision screening tests. NOTE If candidates exhibit abnormal colour vision, practical examinations are recommended to determine the candidate’s ability to different contrast between colours in the applicable NDT method.

Annex H (informative) Canadian comments on ISO 9712 Implementation in Canada of the provisions of the International Standard ISO 9712:1999 is not possible for: a) the “one retake” of initial certification examinations (two retakes are allowed — see 8.4.2) and, b) the “no retake” of recertification examinations (two retakes are allowed — see 10.3.2). Canada claims deviations from ISO 9712:1999 under the provisions of ISO/IEC Guide 21:1999, Adoption of International Standards as regional or national standards. Owing to fundamental climatic, geographical and technical problems, Canada has legitimate reasons for such national deviations as recognized in the Agreement on Technical Barriers to Trade of the World Trade Organization (WTO/TBT Agreement), which Canada signed in 1994. Demographics of Canada Canada has a population of 27 million. Canada has a land mass of 9 million square kilometres (km2), approximately 20 % greater in area than the combined land mass of all the countries in the extended European Economic Community in 1999. Canada’s population density is very low, only 3 persons per km2 as compared with an average of 144 persons per km2 in Europe. To serve a small population spread across the 5000 kilometre breadth of Canada is a challenge. To do this, the certification body has a network of 15 test centres: 10 offer both practical and written examinations and 5 offer written examinations only. The distribution of these test centres across Canada is shown in Figure 1.

CAN/CGSB-48.9712-2000

Initial certification examinations Canada offers a broad-sector certification: Engineering Materials and Components (EMC). This is in contrast to ISO 9712, which is directed at narrow industrial sectors. The extent, duration and difficulty of Canada’s qualification examinations are greater than that for single-sector qualification because candidates must demonstrate a broad theoretical and practical knowledge of manufacturing processes and NDT of welds, casting and forgings. The Canadian qualification process takes longer, costs more and has higher failure rates than would be observed for single-sector certification under ISO 9712:1999. Canada’s three years of experience (1996 through 1999) with the strict “no retake” rule of ISO 9712:1992 demonstrated that this provision was unfair to Canadian candidates. Small mistakes, unfamiliarity with the examination process, and the stress associated with only “one chance to pass” were responsible for the failure of otherwise excellent candidates. Such candidates had to start all over, repeating examinations that they had already passed. This was clearly illogical. While ISO 9712:1999 increases the number of retakes to one, this is still insufficient to meet certification needs in Canada. Therefore, Canada has chosen to allow candidates for initial certification to retake any of the examinations twice. Extensive Canadian experience in certification has shown that one year may be insufficient for candidates to complete the examination process. For example, an examination failure accompanied by unexpected assignment to a remote work location or unexpected sickness has placed candidates outside a one-year time limit. Additional examination retries will require additional time to complete the qualification process. Canada allows a candidate two years to complete the qualification examination after the date of his original examination. Recertification examinations Canada potentially has 3700 certified personnel to recertify before January 1, 2005. Yet, neither the certification body nor the thousands of certified personnel have any previous experience with a recertification process. Thus, there may be problems as Canada implements this for the first time. It may require flexibility on issues, and time to adjust the process so that it works properly. The ISO 9712:1999 policy of “no retakes“ of failed examinations is too onerous to be practical. Since 1987 Canada has offered one certification program, a “broad sector” called Engineering Materials and Components (EMC), which covers plate and pipe welds, castings and forgings. This is in contrast to ISO 9712:1999, which is directed at narrow industrial sectors. This difference creates problems in recertification. Examination in a broadknowledge EMC sector, using an ISO “limited practical examination” or limited number of written questions, is prone to greater scatter in the results and consequently higher failure rates. With recertification occurring only every ten years, and given the diverse nature of the NDT profession, specific-industry requirements often do not follow typical textbook techniques. It is logical that allowance be made for this. Canada is concerned that the ISO policy of “no retakes” of failed examinations will subject the candidates to undue anxiety and stress before and during the examinations, and their performance will suffer, causing higher failure rates. Until the first recertification process is successfully completed, it is not logical to put the certification body in a position of threatening the continuing careers and livelihoods of previously certified candidates. For the candidate, the consequences of failing an examination for recertification are more severe than for initial certification. Since ISO permits one retake for initial certification, it is logical that at least one retake should be permitted for recertification. Note that EN 473:2000 allows one retake of the recertification examinations. According to the results of a September 1998 survey of the members of the Canadian General Standards Board (CGSB) Committee on Nondestructive Testing and Certification of Personnel, the ISO 9712:1999 provision of “no retakes” of a failed recertification examination would be unacceptable to 80 % of Canadian industry. Thus, Canada feels that the “no retakes” provision of ISO 9712:1999 concerning the recertification examination is not suitable for application in Canada. Canada will permit two retakes of failed recertification examinations within the five-year transition period allowed by ISO 9712:1999 to implement levels 1 and 2. Canada believes that all levels of certified personnel should be treated the same; therefore, the five-year, two-retake provision is also extended to level 3 personnel.
