We maintain compliance with the requirements of 10CFR50 Appendix B, NQA-1, and 10CFR21 to support the Nuclear Power Industry.  PH Tool undergoes regular assessments by NIAC member companies, and the results are available to share between NIAC members.  


Quality Assurance Program

quality1smbIn addition to being ISO 9001 certified, PH Tool maintains a stringent ISO 10012 compliant Quality Assurance program governing the precision manufacture and accurate, repeatable inspection of NDT reference standards and test blocks. The quality program at PH Tool has been designed to meet the requirements of these specifications:

  • ISO 9001:2015 Certified
  • ISO 10012 Compliant
  • 10 CFR 50 Appendix B
  • NQA-1, 1994 Ed. through and including 2008 Ed., 2009 Addenda
  • ANSI N45.2
  • ASME Section III Division 1
  • MIL-I-45208
  • MIL-Q-9858A

What kind of paperwork comes with standard test blocks?  All calibration test blocks ship with a NIST-traceable Certification Report stating that the block meets applicable specifications.  A Material Test Report (MTR) is also included to maintain heat or lot traceability of the raw material to the producing mill.  PH Tool also includes a Positive Material Identification (PMI) Test Report with all standard blocks, showing the results of a chemical analysis obtained in-house with our XRF analyzer. The PMI report adds an extra level of certainty that the correct materials were used in manufacture.  If this is not enough, customers also have the ability to purchase a Full-dimensional Inspection Report, showing all of the as-built dimensions of the block.  This is not merely a close approximation of accuracy; the dimensions must be carefully obtained and compiled into a report detailing all of the critical dimensions of the block design.     

Custom EDM Notch, FBH, or other NDT reference standards include a NIST-traceable Certification Report as well.  The as-built dimensions of the EDM notches, FBHs, or other machined features are always included on the report so that you know the precise size.  In cases where PH Tool supplies the material, the MTR and PMI Reports will also be included.
