PREFACE This Standard was prepared by the Australian members of Joint Australia/New Zealand Standards Committee ME-002, Gas Cylinders, to supersede (in part) AS 2030.1—1999, The verification, filling, inspection, testing and maintenance of cylinders for the storage and transport of compressed gases, Part 1: Cylinders for compressed gases other than acetylene. After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard. This edition introduces the following changes: (a)
The main title of the AS 2030 series has been changed and simplified to more accurately reflect the scope of the Standard.
(b)
To clarify the application of the AS 2030 series, the scope of the previous edition of AS 2030.1 has been divided between this Standard (AS 2030.1) and a new Standard, AS 2030.5. This edition of AS 2030.1 essentially contains Clauses 1 to 4 and 10 from the previous edition. AS 2030.1 applies to all gas cylinders, containing requirements for design, manufacture and inspection (including conformity assessment), requirements to be met prior to the first fill and other issues applicable to all cylinders. AS 2030.5 applies to refillable cylinders (except for acetylene, which remains in AS 2030.2), and contains additional requirements for filling, inspection (periodic and non-periodic) and other issues related to refillable cylinders.
(c)
Many terms have been re-defined to harmonize with the terminology of the Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code), which in turn takes its definitions from UN Model Regulations on the Transport of Dangerous Goods. Of necessity, some terms have definitions that are not the same as the ADG Code. Of these the most significant are the following:
0 1 0 2 y a M 3 0 n o D T L Y T P S R E Z I L I T R E F P U R R U B y b d e s s e c c A
(i)
This Standard retains the generic term ‘gas cylinder’. The corresponding ADG Code term ‘transportable pressure receptacle’ is generally equivalent to a gas cylinder as defined in this Standard, except that a transportable pressure receptacle may include certain items which are built to a general pressure vessel code, whereas such items are specifically excluded from the scope of this Standard.
(ii)
This Standard also retains the generic term ‘welded gas cylinder’, rather than the ADG Code term ‘pressure drum’, because ‘pressure drum’ may include general pressure vessels.
Appendix C provi des a comparison of the definitions used in this Standard, AS 2030.1—1999 and the ADG Code. Note that some gases formerly classified as compressed (permanent) are now classified as high pressure liquefied gases. (d)
Clause 4 from the previous edition has been expanded and clarified to address in more detail cylinder design and manufacture, manufacturing and inspection, filling for the first time in Australia, and periodic inspection. Requirements for inspection bodies now are given, as well as guidance on assessing the competence of design verifiers.
3
(e)
AS 2030.1—2009
Requirements for certified gas cylinder test stations (set out in AS 2337.1) have been clarified and some associated terminology has been updated to reflect current issues.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance. IT SHOULD BE NOTED THAT COMPLIANCE WITH THIS STANDARD MAY NOT NECESSARILY FULFILL ALL LEGAL OBLIGATIONS.

AS 2030.1—2009
FOREWORD This revision of AS 2030 continues a tradition of more than 75 years, since the original release of AS CB4—1931, of setting out technical requirements for the design, type testing, verification, manufacturing, inspection, documentation and filling of gas cylinders. The Standard reflects the considerable body of experience accumulated over the years by the compressed gas industry and codified by the Australian members of Standards Australia Committee ME-002, Gas Cylinders. Together with its many subordinate standards, especially AS 2337.1—2004, Gas cylinder test stations, Part 1: General requirements, inspection and tests—Gas cylinders, AS 2030 has specified and documented a voluntary technical working model for gas cylinders in Australia. Over this period, the regulatory environment for gas cylinders has evolved considerably, as has the relationship between regulations and this Standard. The most significant current regulations are probably the National Standard for Plant [NOHSC:1010(1994)], the Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code), and the local regulations which implement these in the various states and territories. These regulations and codes may refer to AS 2030 for technical specifications and details. Despite these references, AS 2030 rem ains a technical standard limited to setting out specifications, test methods and in general providing a technical model for gas cylinders requirements. The regulations and codes specify requirements which may be covered partially or not at all in AS 2030. Conversely, not all the AS 2030 requirements may lead to action by the regulatory authorities. This applies particularly to the requirements for the manufacture and manufacturing inspection of gas cylinders o utside Australia. Hence, users of AS 2030 should be fully aware that implementation of this Standard’s specifications and guidelines is totally outside its jurisdiction, and they need to refer to the relevant regulations and codes to determine their responsibilities and obligations. It cannot be emphasized too strongly that compliance with this Standard may not necessarily fulfil all legal obligations.

8 CARE AND HANDLING 8.1 General
A gas cylinder should always be presumed to contain pressure, even when gas is not released when the valve is opened. Cylinder valves shall not be disassembled nor removed from a cylinder, except by qualified personnel and with the permission of the cylinder owner. 8.2 Storage, handling and transportation
A gas cylinder shall only be used for the storage and transport of gases and substances for which it was designed. NOTES: 1
For storage and handling of gas cylinders, the following Standards provide guidance: AS/NZS 1596, AS 3848 Parts 1 and 2, AS 4289, AS 4332, AS 4839, AS 5034 and ISO 11625.
2
For transport, reference should be made to the ADG Code, and to relevant State, Territory and Commonwealth regulations pertaining to dangerous goods and/or hazardous substances.
8.3 Avoidance of oil, grease and water
Neither oil nor grease shall be allowed to come into contact with the valves or cylinders used for the storage and transport of any gas. Particular care shall be taken to prevent contamination of any cylinder which contains oxygen, nitrous oxide, chlorine, any other oxidizing agent or any gas for human respiration. Care shall be taken to ensure that water is not allowed to enter a cylinder between hydrostatic test or inspections. NOTE: Exclusion of moisture and other potentially corrosive materials is particularly important for cylinders manufactured from high strength steel where the relatively thin walls provide little corrosion allowance.
8.4 Closing valves for transportation
The shut-off valve for each cylinder shall be closed during transportation. 8.5 Cylinders for toxic gases
A gastight seal shall not be removed from a toxic gas cylinder unless appropriate protection (e.g. personal protective equipment) is afforded to the person(s) removing the seal. While the seal is being removed, a check for leakage shall be carried out. 0 1 0 2 y a M 3 0 n o D T L Y T P S R E Z I L I T R E F P U R R U B y b d e s s e c c A
8.6 Need to keep cylinders cool
Filled cylinders shall be kept away from sources of heat which are likely to overheat the cylinder, above its maximum working temperature. 8.7 Avoidance of shock
Cylinders should not be allowed to fall upon one another or be otherwise subjected to undue mechanical shock. During transport and use, cylinders shall be secured. 8.8 Correct orientation
Cylinders filled with liquefied gas shall be transported, stored and used in a manner which ensures that the safety device is in direct contact with the vapour space.
