Encyclopedia
The National Institute of Standards and Technology (NIST), known between 1901 and 1988 as the National Bureau of Standards (NBS), is a measurement standards laboratory, otherwise known as a National Metrological Institute (NMI), which is a non-regulatory agency of the United States Department of Commerce

. NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel. About 1,800 NIST associates (guest researchers and engineers from American companies and foreign nations) complement the staff. In addition, NIST partners with 1,400 manufacturing specialists and staff at nearly 350 affiliated centers around the country. NIST publishes the Handbook 44 that provides the "Specifications, tolerances, and other technical requirements for weighing and measuring devices".

Initial mandate

In 1821 John Quincy Adams stated, "Weights and measures may be ranked among the necessities of life to every individual of human society.", but this had long been understood. The Articles of Confederation

Article 1, section 8, of the Constitution of the United States (1789), transferred this power to Congress; "The Congress shall have power ... To coin money, regulate the value thereof, and of foreign coin, and fix the standard of weights and measures".

 and if it can be derived from a standard at once invariable and universal, must be no less honorable to the public council than conducive to the public convenience." , but it was not until 1838 that a uniform set of standards was worked out.

History of agency

From 1830 until 1901, the role of overseeing weights and measures was carried out by the Office of Standard Weights and Measures, which was part of the U.S. Treasury Department.

The "Office of Weights and Measures" became the "National Bureau of Standards" on July 1, 1901, which was reorganized into the National Institute of Standards and Technology on 1988. In 1905 a meeting was called that would be the first "National Conference on Weights and Measures".

Metric system

The Congress of 1866 legalized the use of the metric system through the passage of US code 1952 Ed., Title 15, Ch 6, section 204 and 205. On May 20, 1875, 17 of 20 countries signed a document known as the Metric Convention or the Treaty of the Meter which established the International Bureau of Weights and Measures

NIST also is providing practical guidance and tools to better prepare facility owners, contractors, architects, engineers, emergency responders, and regulatory authorities to respond to future disasters. The investigation portion of the response plan was completed with the release of the final report on 7 World Trade Center on November 20, 2008. The final report on the WTC Towers – including 30 recommendations for improving building and occupant safety – was released on October 26, 2005.
