First published in 1946, the National Board Inspection Code (NBIC) is an internationally recognized standard that governs and maintains rules for the installation, inspection, repair, and alteration of inservice pressure equipment. The NBIC is adopted into law by most US and Canadian jurisdictions. It is the basis for NBBI’s four accreditation programs (R, VR, NR, and T/O) and is utilized by more than 5,200 repair organizations in over 60 countries. The NBIC is recognized as a national standard by the American National Standards Institute (ANSI).

The NBIC is organized into four (4) Parts to coincide with specific post-construction activities involving pressure-retaining items.

The NBIC is developed and maintained by a consensus committee, the NBIC Main Committee, composed of industry experts.

The NBIC Main Committee updates the NBIC every other year. The updates are presented on the National Board’s website for public review in August of the year prior to the Edition date. The NBIC is published as a new edition in July of odd numbered years (2017, 2019, 2021, 2023).

The NBIC Committee Information includes a description of the NBIC committee structure, committee members, meeting schedules, minutes, and agendas.

The NBIC Publication Information describes announcements about documents for public review. It also contains errata and interpretations for several NBIC Editions.

The NBIC Committee Log-In is restricted to members of the NBIC Main Committee, subcommittees, and subgroups. It was developed for the recording of letter ballots, allowing committee members to vote on items electronically.
