Inspection Code

Print Date: 6/29/2022 5:36:01 PM

The National Board Inspection Code (NBIC) was first published in 1946 as a guide for chief inspectors. It has become an internationally recognized standard, adopted by most US and Canadian jurisdictions. The NBIC provides standards for the installation, inspection, and repair and/or alteration of boilers, pressure vessels, and pressure relief devices.

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, etc.).

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.
