TO BE USED ON OR AFTER NOVEMBER 3, 2013 Nadcap

AUDIT CRITERIA FOR NONDESTRUCTIVE TESTING FACILITY MAGNETIC PARTICLE SURVEY

1 SCOPE These Audit Criteria define the requirements for suppliers seeking Nadcap accreditation in Magnetic Particle and

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 Magnetic Particle. Note: This checklist is not applicable to the Yoke or Permanent Magnet techniques.

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/As 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.

Compliance Assessment Guidance: The auditor shall verify compliance to each of these requirements by direct observation: 7.5.1 Did the inspector(s) review, as applicable, the specification(s), technique sheet, and

procedure(s) prior to inspecting the part?

YES NO

7.5.2 Are parts being cleaned in accordance with applicable work instructions/procedure prior to inspection?

YES NO

PRI AC7114/2 Rev. G - 19 -

7.5.4 Was the magnetic particle suspension properly agitated?

Compliance Assessment Guidance: The magnetic particle suspension shall be agitated throughout to provide a uniform concentration of particles in suspension as demonstrated via the concentration result.

YES NO

7.5.5 Were parts properly magnetized in accordance with the procedure or technique sheet?

YES NO

7.5.6 Was suspension properly applied to the parts? Compliance Assessment Guidance: The suspension shall be applied to the surface of the part(s) in a manner providing total coverage. The suspension shall not be applied using pressure of such magnitude that would cause excessive splashing.

YES NO

7.5.7 Did the inspector(s) adhere to the requirement of not wearing photo chromatic eye glasses or permanently darkened lenses? Compliance Assessment Guidance: This is not intended to prohibit the use of eyeglasses with lenses treated to absorb ultraviolet light.

YES NO

7.5.8 Did the inspector(s) accustom their eyes to darkness for at least one minute before performing any inspection requiring the use of black light? Compliance Assessment Guidance: Inspectors shall allow at least 1 minute to condition their eyes to the darkness when coming in from ambient lighting. Adaptation time during inspection and evaluation is not required unless otherwise specified by the customer. A timing device is required for eye adaptation monitoring, but evidence of calibration is not required.

YES NO

7.5.9 If required, were parts demagnetized between each operation? Compliance Assessment Guidance: Parts shall be demagnetized between each operation where the strength of the magnetizing field is not sufficient to overcome the residual field of the previous magnetization.

YES NO N/A

7.5.10 If applicable, when current is passed directly through the part (direct head shot) was care exercised to prevent burning/arcing of the part at the contact areas? Compliance Assessment Guidance: When current is passed directly through the part (direct head shot), burning/arcing between the contact areas of the machine and the part shall not occur.

YES NO N/A

7.6 Inspection Evaluation Process

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. 7.6.1 Was the black light intensity measured at the time of this survey, at least 1200 W/cm2

at the inspection surface?

YES NO

7.6.2 Were all areas of the part inspected per the technique sheet or procedure? YES NO

7.6.3 If applicable, did the inspector(s) properly evaluate every relevant indication in accordance with the customer standard?

YES NO N/A

7.6.4 Was the specific acceptance criteria properly understood by the inspector(s)? Compliance Assessment Guidance: The auditor is expected to confirm understanding by whatever means are required. This may be possible by observation or in some

YES NO

PRI AC7114/2 Rev. G - 20 -

cases may require the auditor to ask the inspector(s) questions regarding the criteria and how it is to be used.

7.6.5 Were precautions taken when parts were handled during inspection not to smear or obliterate indications?

YES NO

7.6.6 If applicable, were indications not meeting the acceptance criteria marked on the part and/or appropriately documented? Compliance Assessment Guidance: The auditor is expected to validate that the appropriate marking materials are utilized in accordance with customer requirements.

YES NO N/A

7.6.7 After evaluation, were all parts demagnetized and exhibit no more than an absolute value of 3 gauss or 240 A/m as determined by the use of a field indicator on the surface of the part?

YES NO

7.7 Post Cleaning

Compliance Assessment Guidance: The auditor shall verify compliance to this requirement by direct observation. 7.7.1 Were parts properly cleaned after magnetic particle inspection to remove magnetic

particle residues from holes, crevices, passage ways, etc? Compliance Assessment Guidance: Cleaning shall be done with a suitable solvent or by other means with all plugs, masking, or other processing aids removed with care as they may affect the intended use of the part.

YES NO

7.7.2 After inspection and appropriate cleaning, were parts properly protected from corrosion or damage?

YES NO N/A

7.8 Inspector Qualification

7.8.1 Were the inspection personnel certified to the correct levels for the work they were performing? Compliance Assessment Guidance: This shall be verified by review of the certification records.

YES NO

7.8.2 Were all non-certified or in-training personnel observed performing magnetic particle process operations properly supervised? Compliance Assessment Guidance: This shall be determined by direct observation.

YES NO N/A

7.8.3 Were all personnel who require near vision correction to pass the visual acuity exam wearing vision correction for detection and evaluation purposes during testing/inspections? Compliance Assessment Guidance: The auditor shall verify that corrective lenses were used if required. N/A only where none of the inspection personnel witnessed working required correction lenses.

YES NO N/A

7.9 Inspection Status

7.9.1 Were symbols and/or marking methods used to denote magnetic particle inspection status?

YES NO

7.9.2 Were all inspection results properly recorded and traceable to the parts? YES NO
