Nation Board of B&PV Inspectors
Chapter 1– Origin, Development and Jurisdiction of ASME Code
Steam drove the Industrial Revolution during the mid-19th century. At this point in history, conversion of water was considered both good and bad. Good - powered industrial progress, Bad - boilers used employed new and unproven technology.
The ASME Code provided a solid reference of construction standards, it lacked an important component: the authority to regulate.
This was complicated by existence of local and state jurisdictions having their own codes and standards.
On December 2, 1919, Ohio Chief Inspector Carl Myers met with chief inspectors. This was the genesis of The National Board of Boiler and Pressure Vessel Inspectors.

Chapter 1– Origin, Development and Jurisdiction of ASME Code
The NBIC was first published in 1945 and is today the only standard recognized worldwide for inservice repair and alteration of boilers and pressure vessels.
Approved as (ANSI) in August 1987, the National Board Inspection Code has been adopted by a number of states and jurisdictions, as well as federal regulatory agencies, including the US Department and Nuclear Regulatory Commission (nuclear only).
