February 19, 1987 Docket No.: 99901033 MEMORANDUM FOR:
Chester W. White, Director Office of Investigations Field Office Region I FROM:
Ellis W. Merschoff, Acting Chief Vendor Program Branch Division of Quality Assurance, Vendor and Technical Training Center Progrems Office of Inspection and Enforcement
SUBJECT:
REGION I 0FFICE OF INVESTIGATIONS (01) CASE NO.
1-86-004: POWER INSPECTION, INC./ FALSIFICATION OF EDDY CURRENT EQUIPMENT CERTIFICATION DOCUMENTS Your memorandum to me dated December 12, 1986 on the above subject requested a written response from the Vendor Program Branch to the following questions:
1.
Assuming that uncalibrated eddy current equipment gave responses to calibration standard defects within an acceptable tolerance of the actual defect size, could the uncalibrated equipment miss defects when used during actual production in a way that may have been detected by the proper calibration of individual components traceable to the National Bureau of Standards?
2.
10 CFR 50, Appendix B, Criterion XII states, in part, that " testing devices used in activities affecting quality" must be " calibrated" at "specified periods."
Article 8 of the ASME Code (under Equipment Specifications) indicates that eddy current equipment must be certified as being calibrated
" annually."
Is this a fair reading of the Code and is this section of the Code the governing document that pertains to 10 CFR, Appendix B, which states that test equipment must be calibrated at "specified pericds."
Following discussions with knowledgeable people in eddy current testirg (ET) from the Engineering Branch of the Office of NRR, it has been determined that additional information is needed to respond correctly to these two hypothetical questions.

Chester White February 19, 1987 In response to question No.1, the relative influence of each particular component (type and model number) being in or out of calibration would have to be known to determine the effect of the overall detection capabilities of the integrated system. This would also include the relationship between the components and component subassemblies taking into account the specific tolerances of each instrument.
With regard to question No. 2, requirenents for ET vary with different editions and addenda of the ASME Code and licensee documents such as the Inservice Inspection Program, Technical Specifications, and administrative and technical procedures. Accordingly, information related to ET in each document in effect when the testing took place should be reviewed to determine the actual cali-bration requirements of the ET equipment.
You may find it useful to consult with personnel involved with the NRC's NDE Van for answers to questions involving specific testing devices. Should you have any further questions, please contact me at FTS 492-9663 or James T. Conway at FTS 492-8340.
