GENERAL INFORMATION INFORMATION In completing this assessment, auditors are instructed to respond with a "Yes” or “No" to address compliance with each statement of requirement. For any negative responses, the auditor must clearly indicate in the NCR if the “No" reflects noncompliance with respect to existence, adequacy, and/or compliance. Existence relates to evidence of a documented procedure or policy, adequacy relates relates to the com pleteness of the procedure or policy, and compliance relates to evidence of effective implementation. This checklist includes the use of the word “shall” which indicates a clear requirement that must be met at all times. The word “may” indicates a possible resolution to a requirement or one recommended method to achieve a given requirement, but does not represent the only way to meet that requirement. In addition the checklist includes the term “Compliance Assessment Guidance”. This term is used to reflect the T ask Groups expectation when answering the checklist question as YES or N/A. The auditor must verify the list of procedures provided by the supplier at the time of the audit. Any corrections or updates to the list must be identified using notes, inserted at the applicable criterion.  All negative responses require a Nonconformance Report (NCR). Not Applicable (N/A) responses responses do not require require an explanation unless otherwise noted. There is only one plausible reason for an N/A, which is, that a particular operation or issue is not being used at the supplier. There are no N/A’s simply for a lack of a customer requirement. If a system is in use, then all questions pertaining to that system are applicable. If verification of results require documentation it shall be so noted in this checklist. The audit results shall not include any customer proprietary information. Technical information on parts which have been designated “Export Controlled – License Required” (EC-LR) cannot be input into eAuditNet. If auditors have any questions about this, they should contact the Staff Engineer for directions. GO FORWARD PLAN – Any new or revised procedure made after 4 December 2006 requires compliance to the following requirements. Procedures written written prior to this date shall be acceptable; however a system needs to be in place to ensure that changes reflect the current Nadcap requirements.

These parts shall be selected to represent a variety of Nadcap participating customer requirements and several different types of processing equipment if more than one radiographic system is in use at this facility. Borrowing hardware from one company to another to demonstrate compliance is not acceptable; unless there is objective evidence the design authority has authorized movement of the hardware to the company undergoing the audit. Investigate the purchase order specifications to identify any customer unique acceptance, process control, or procedure requirements applicable to these parts. If composites are processed, at least one job will include composites. Witness the facility's ability to perform inspection of these parts in accordance with the requirements. If there are trainees being utilized by the facility, it is expected that the auditor makes every attempt to witness them performing in a compliance job. It is expected that the auditor shall review and follow traceability from the purchase order to completion of the NDT process or final certification by reviewing as a minimum the items listed below. The auditor shall verify that the process applied complies with the procedural system established by the company in terms of flow down, customer specification retrieval (as applicable), inspection identification, etc.
