AUDIT CRITERIA FORNONDESTRUCTIVE TESTING FACILITY PENETRANT SURVEYEditorial Change was made to Section 6.1 on December 03, 2014

Editorial Change made to reflect the Nadcap Audit Criteria Template Form on 08 January 2015

Editorial Change made to Section 2.1 on April 19, 2015

1. SCOPE

These Audit Criteria define the requirements for suppliers seekingNadcap accreditation in Penetrant and are to be used as supplement toPRI AC7114. These criteria and the applicable User PrimeSupplemental Checklists will ensure that NDT suppliers meet therequirements for Nadcap accreditation in Penetrant.

2. GENERAL INFORMATION

In completing this assessment, auditors are instructed to respond witha "Yes or No" to address compliance with each statement ofrequirement. For any negative responses, the auditor must clearlyindicate in the NCR if the No" reflects noncompliance with respect toexistence, adequacy, and/or compliance. Existence relates to evidenceof a documented procedure or policy, adequacy relates to thecompleteness of the procedure or policy, and compliance relates toevidence of effective implementation. This checklist includes the use ofthe word shall which indicates a clear requirement that must be metat all times. The word, may indicates a possible resolution to arequirement or one recommended method to achieve a givenrequirement, but does not represent the only way to meet thatrequirement. In addition the checklist includes the term Compliance

Assessment Guidance. This term is used to reflect the Task Groupsexpectation when answering the checklist question as YES or NA.

The auditor must verify the list of procedures provided by the supplierat the time of the audit. Any corrections or updates to the list must beidentified using notes inserted at the applicable criterion.

All negative responses require a Nonconformance Report (NCR). NotApplicable (NA) responses do not require an explanation unlessotherwise noted. There is only one plausible reason for an NA, whichis, that a particular operation or issue is not being used at the supplier.There are no NAs simply for a lack of a customer requirement. If a

system is in use, then all questions pertaining to that system areapplicable. If verification of results require documentation it shall be sonoted in this checklist.

The audit results shall not include any customer proprietaryinformation. Technical information on parts which have beendesignated Export Controlled License Required (EC-LR) cannot beinput into eAuditNet. If auditors have any questions about this, theyshould contact the Staff Engineer for directions.

GO FORWARD PLANAny new or revised procedure made after 4December 2006 requires compliance to the following requirements.

Procedures written prior to this date shall be acceptable; however asystem needs to be in place to ensure that changes reflect the currentNadcap requirements.

5.9 Penetrant System Performance

5.9.1 Has the supplier performed an initial check to establish a baseline foreach known defect standard and material in use?

YES NO

Compliance Assessment Guidance: The supplier shall perform an initialcheck with all new materials to establish a baseline for each known

defect standard and material in use. This check shall be performedutilizing a color photograph approximately 1:1, whose background doesnot interfere with the comparison or by direct comparison of usedversus unused materials; to record the baseline performance. Therequirement is that the performance of the in use materials can not fallbelow that of the unused materials. Therefore a baseline performancemust be established to compare to the daily results. The requirementfor a photo does not apply when directly comparing new and in usematerials utilizing two identical test panels. (example: NiCr Panels)

NOTE: The establishment of the baseline photo may be performed byan external source providing that the color photo is representative ofthe panel when run at the suppliers facility. The outside source shall

process the panel utilizing the same penetrant materials and testparameters as the supplier and produce a color photo of approximately1:1 scale.

5.9.2 Is the penetrant system performance checked at least daily or prior touse?

YES NO

Compliance Assessment Guidance: The check is intended to beperformed at least prior to use, that is if the system is not used everyday, the check would not be required to be performed every day. Thischeck includes all in use materials, recycled and not recycled howevera change in the penetrant application method from the same containershall not necessitate another system performance check. Forexample: brush on, electrostatic application, dipping, and pouring fromone container would not require separate checks for the same

penetrant from the same container.

NOTE: This includes materials sprayed to waste but is not applicableto Method C penetrant utilized from sealed aerosol containers.


Compliance Assessment Guidance: Results of the system performance


11/33

PRI AC7114/1 Rev. H - 11 -

test, utilizing the in-use materials, must indicate the same number andappearance (e.g. size, etc.) of the flaws detected originally when thebaseline was established. Example: If 4 stars of a certain size andappearance are originally detected, then the same number andappearance of the stars is expected each subsequent test and the

actual number must be recorded. This comparison shall be madeutilizing a color photograph (approximately 1:1, whose back grounddoes not interfere with the comparison) or by direct comparison of usedversus unused materials.


Compliance Assessment Guidance: The objective of the systemperformance test is that it be used as a comparison tool. Thatcomparison day to day may either be performed utilizing the samesystem parameters as the original (i.e. materials, dwell times,temperatures, etc), or may be processed in the same manner as

production components, but the method of processing shall beproceduralised. The system performance test shall be witnessed by theauditor with all aspects performed properly.

5.9.5 Does the procedure address the actions to be taken when thesensitivity or performance of the in-use materials falls below theperformance of the unused materials?

YES NO

5.10 Known Defect Standard Maintenance / Degradation

5.10.1 Are there maintenance procedures in place that assure that cleaning ofthe known defect standards, between usage, is adequate and that

physical changes in the standard that make it unsuitable for use, canbe detected?

YES NO

Compliance Assessment Guidance: The procedure must define what isactually done by the supplier. The auditor shall require that thetechnician demonstrate that the panel or test standard is clean andindication free prior to performance of the test. Unless defined bysupplemental requirements, this does not require application ofdeveloper.

5.10.2 Is a degradation check performed for the known defect standard atleast annually?

YES NO NA

Compliance Assessment Guidance: This check must be performed bycomparing the original results obtained utilizing all new materials to thecurrent results, also using all new materials. This check is a check ofthe defect standard, not of the system. It shall be performed utilizingmeasurements Any suitable method may be used to measure theindications (e.g. inscribed circle, longest length) but the method usedshall be defined and repeated for the degradation measurement.. Thedegradation check is not applicable if the defect standard is replacedbefore the requirement comes due or for known defect standardswhere a direct comparison of new versus in-use materials is made on adaily basis.


12/33

PRI AC7114/1 Rev. H - 12 -

Compliance Assessment Guidance: The supplier shall performrepresentative inspections from current production to determinecompliance with these requirements. These parts shall be selected torepresent a variety of Nadcap participating customer requirements andseveral different types of processing equipment if more than one

penetrant line is in use at this facility. Borrowing hardware from onecompany to another to demonstrate compliance is not acceptable;unless there is objective evidence the design authority has authorizedmovement of the hardware to the company undergoing the audit.Investigate the purchase order specifications to identify any customerunique acceptance, process control, or procedure requirementsapplicable to these parts. Witness the facilitys ability to performinspection of these parts in accordance with the requirements.

It is expected that the auditor shall review and follow traceability fromthe purchase order to completion of the NDT process or finalcertification by reviewing as a minimum the items listed below. Theauditor shall verify that the process applied complies with the
