What The National Board of Boiler and Pressure Vessel Inspectors does
The National Board of Boiler and Pressure Vessel Inspectors (NBBI) is a private, non-profit membership organization founded in 1919 and headquartered in Columbus, Ohio. It is the principal North American standards body for boiler, pressure vessel, and pressure relief device safety, maintaining the National Board Inspection Code (NBIC) — first published in 1946 and adopted by most US states and Canadian provinces. NBBI's membership spans 47 US jurisdictions (states, cities including Chicago and New York) and 14 Canadian jurisdictions (ABSA, TSSA, BCSA, Quebec, and others), giving it a quasi-regulatory role across the continent.
The organization operates a portfolio of credentialing, accreditation, and digital workflow products. Its JRS (Jurisdictional Reporting System) platform provides standardized inservice inspection workflows for jurisdictions, insurers, and inspection agencies, while JRS Register (formerly EDT) handles electronic registration of manufacturer data reports and repair reports. The NB-18 searchable database catalogs certified pressure relief devices, manufacturers, and assemblers; the Testing Laboratory in Worthington, Ohio physically tests pressure relief devices at pressures up to 2,025 psi. NBBI additionally issues commissioned inspector credentials (AI, IS, N, I, C, NS, B, R, O endorsements), accredits repair organizations via R, NR, VR and T/O Marks, authorizes manufacturers to use the NB Mark for pressure-retaining items, and sells the NBIC and related publications. Training is delivered in person in Columbus and virtually, with examinations administered through the Prometric testing network.
Revenue is generated through four principal lines: per-item fees for data report registrations, training tuition ($2,300-$4,200 per course), examination fees ($170 commission / $100 endorsement), and sales of publications and accreditation marks. The leadership team disclosed includes Mark Mooney as Director of Operations - Software and Services. The organization markets through its website, the BULLETIN newsletter, social channels, an annual General Meeting (the 95th scheduled for May 9-12, 2027 in Honolulu), and the Business Center online portal — with the jurisdiction member network providing referral pipeline for new participants.

The National Board of Boiler and Pressure Vessel Inspectors competitors and assessment
Company assessmentBroad incumbents
- DNV: DNV provides certification, inspection, and asset integrity services to the energy, maritime, and process industries, including pressure equipment standards and verification. It is a broad incumbent with comparable TIC capabilities in NBBI's core energy-infrastructure domain.
- DEKRA: DEKRA is a global TIC organization providing industrial inspection, certification, and asset integrity services. It has comparable pressure equipment and process safety inspection capabilities that overlap with NBBI's accredited agency network.
- TÜV SÜD: TÜV SÜD is a global testing, inspection, and certification (TIC) firm with pressure equipment and industrial plant inspection services. It is a broad incumbent that operates across many industries, including the pressure equipment and energy infrastructure categories where NBBI sets standards.
- TÜV Rheinland: TÜV Rheinland is a global TIC firm providing pressure equipment testing, inspection, and certification services under EN/ISO frameworks. It is a broad incumbent that competes with NBBI's network of accredited AIAs for industrial inspection work globally.
- Bureau Veritas: Bureau Veritas is a global TIC company providing asset integrity and pressure equipment inspection services to the energy, marine, and process industries. It competes for industrial inspection work in the same energy-infrastructure verticals that NBBI's accredited agencies serve.
- Intertek: Intertek is a global TIC provider offering industrial inspection, asset integrity management, and certification services across multiple industries, including energy and process sectors where pressure equipment inspection is a core offering.
Others
- Factory Mutual (FM Insurance): FM Global is a major industrial insurer and an AIA accredited by NBBI for inservice inspections. It operates as a customer and complementary inspection provider within the NBBI ecosystem, rather than a competing standards body.
- American Petroleum Institute (API): API is a US standards body for the oil and gas industry that issues complementary standards (e.g., API 510, 570, 653) for pressure equipment integrity in upstream and downstream operations. It is thematically adjacent and occasionally overlapping in scope with NBBI's NBIC.
- Hartford Steam Boiler (HSB): HSB is a leading equipment breakdown insurer and an AIA accredited by NBBI to perform inservice inspections. As both a customer and a complementary service provider, HSB is ecosystem-adjacent to NBBI rather than a direct competitor.
Direct peers
- ASME (American Society of Mechanical Engineers): ASME co-develops the Boiler and Pressure Vessel (BPV) Code, the foundational technical standard on which NBBI's NBIC and registration system are built. Both organizations occupy the same pressure-equipment standards ecosystem and have overlapping stakeholder communities of manufacturers, AIAs, and inspectors.
