AUDIT CRITERIA

AC7114/4 REV. G

Issued 1997-07 Revised 2013-7 Superseding AC7114/4 Rev F

TO BE USED ON OR AFTER NOVEMBER 3, 2013 Nadcap

AUDIT CRITERIA FOR NONDESTRUCTIVE TESTING FACILITY FILM RADIOGRAPHY SURVEY

1 SCOPE These Audit Criteria define the requirements for suppliers seeking Nadcap accreditation in Film Radiography and

shall are to be used as a supplement to PRI AC7114. These criteria and the applicable User Prime Supplemental Checklists will ensure that NDT suppliers meet the requirements for Nadcap accreditation in Film Radiography. Note: This checklist is not applicable to film-less or digital radiography.

2 GENERAL 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 to the completeness 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 Task 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 do not 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 prior to this date shall be acceptable; however a system needs to be in place to ensure that changes reflect the current Nadcap requirements.

to determine compliance with these 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.

YES NO

6.5.2 Were parts properly positioned on the film as defined by the technique?

YES NO

6.5.3 Were identifiers and markers utilized properly as defined by the technique?

YES NO

6.5.4 Were the correct exposure parameters set and used as defined by the technique?

YES NO

6.5.5 Was IQI selection and placement as defined by the technique?

YES NO N/A

6.5.6 Was a sufficient number of IQI’s used to represent the material thickness range as defined by the technique?

YES NO N/A

6.5.7 Were the correct shims used as defined by the technique?

YES NO N/A

6.5.8 Was backscatter monitored per customer requirements? YES NO N/A

6.6 Film Processing

Compliance Assessment Guidance: The auditor shall verify compliance to each of these requirements by direct observation.

6.6.1 Was the film processed to the established times and conditions? Compliance Assessment Guidance: This requirement shall be procedurally defined.

YES NO

6.6.2 Did film processing equipment and dark room procedures yield developed film that is free of stains, scratches, light streaks, fogging, or other artifacts, which might interfere with film interpretation? Compliance Assessment Guidance: This issue shall be investigated and confirmed by the auditor.

YES NO

6.7 Film Viewing

Compliance Assessment Guidance: The following evaluation process shall be determined by direct observation, and by researching the specifications, procedures and other customer documents that are applicable and required to reach an educated answer to each question. 6.7.1 Was film verified for proper identification, density, and quality level?

YES NO

6.7.2 Was the area of interest clearly defined and viewable on the finished radiograph?

YES NO

6.7.3 Did the inspectors allow sufficient time after entering the viewing area for eye adaptation or re-adaptation before interpreting radiographs? Compliance Assessment Guidance: The inspectors shall wait sufficient time, but, not less than 1 minute, after entering the viewing area, before interpreting radiographs to ensure that the features of the IQI are visible and the required sensitivity is displayed. If the eyes are momentarily subjected to the full brightness of the illuminator at least 30 seconds re-adaptation shall be required.
