Report

The student will be able to describe:
◦ the history of ASME and the National Board
◦ the history of the National Board Inspection Code
◦ how the NBIC becomes an American National Standard
◦ how the NBIC has changed through the years
◦ the current format of the NBIC

Industry used waterways for a source of
power to run production equipment in the
1700s and early 1800s.
In the 1800s, factories needed to move closer
to where raw materials were.
Without waterways, steam became a source of
power to operative equipment.
The steam generators/boilers had a tendency
to explode, causing up to 50,000 deaths and
2 million injuries annually.



States and cities establish their own
construction rules for their jurisdictions. No
national standard existed.
There was no uniformity or interchangeability
between states, cities, and counties.
Manufacturers had to satisfy requirements of
each jurisdiction in which the boiler was
manufactured. Many had none.
Boiler manufacturers and insurance
companies asked ASME to develop a single
standard in 1910.


ASME published the first boiler code in 1915.

Getting ASME Code adopted by Jurisdictions was a
struggle.

The National Board was formed in 1919.


National Board formed to unify Jurisdictions and
enforcement; provide standardization and
interchangeability.
In 1921 The National Board:
◦ Commissioned its first inspector.
◦ Commenced registration of boilers.

A manual for the Inspector.
Recommended Legislation, Rules and
Regulations for Boiler and PV Safety (NB-131,
NB-132).
NB members understood problems and
difficulties inspectors faced. This provided
the basis for developing the NBIC:
• New designs—increased pressures and
temperatures
• Improved technology—appurtenances, materials,
fabrication, etc.

Recognized worldwide.
Procedures based on consensus (openness,
balance, due process):


What is a Jurisdiction?
◦ A government entity with the authority to make
laws governing activities within its borders.
◦ Jurisdiction could be a Township, County, City,
State, or Province.
16

Jurisdictions may have additional
requirements in statute or rule.
◦ May require boiler and pressure vessel repairs or
alterations to be registered with National Board.
◦ May require the Repair Organization to have
jurisdictional license.
◦ May require a Repair Organization to have an “R”
stamp.
◦ May have special rules governing routine repairs.
◦ May require an official approval before starting
any work.
