Below are some commonly asked questions concerning the "new" NBIC:
  • Which part or parts of the NBIC are necessary for "R," "NR," and "VR" certificate holders to have in their possession?
    - Parts 1, 2, and 3.

  • What is required when an accredited repair organization changes its scope or location from that listed on its Certificate of Authorization?
    - The QC Manual must be revised and accepted by the Authorized Inspection Agency (AIA). A revised application form (NB-12) must be submitted to the National Board.

  • What is required if the AIA of record has changed?
    - Proof acknowledging a new AIA agreement must be submitted to the National Board.

  • When performing a pressure test of a repair or alteration (excluding re-rating), is it permissible to isolate the repaired or altered area such that the remaining parts of the pressure-retaining item are not subjected to pressure?
    - Yes.

  • Are repair methods not specifically identified in the NBIC allowed to be used by repair organizations?
    - Yes, provided concurrence of the inspector and jurisdiction is obtained.

  • Should the jurisdiction be contacted when the original manufacturer's name plate or stamping is determined during an inservice inspection to be lost or illegible?
    - Yes. Form NB-136 must be used for this purpose, but only ASME can authorize the restamping of ASME code symbols.

  • Do references to other codes or standards in the NBIC imply acceptance for use?
    - No. Each jurisdiction retains the responsibility to decide which codes or standards are adopted for use.
