National Board of Boiler and Pressure Vessel Inspectors

The National Board of Boiler and Pressure Vessel Inspectors was founded in 1919 to promote greater safety to life and property through uniformity in the construction, installation, repair, maintenance, and inspection of pressure equipment. Publisher of the National Board Inspection Code (NBIC), this American National Standard has been adopted by most states and cities, all Canadian provinces, and federal regulatory agencies including the US Department of Transportation. It is the only standard recognized worldwide for in-service inspection repairs and alterations of boilers and pressure vessels.
