The NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST) is a measurement standards laboratory, and a non-regulatory agency of the United States Department of Commerce . Its mission is to promote innovation and industrial competitiveness.
NIST's activities are organized into laboratory programs that include Nanoscale Science and Technology, Engineering, Information Technology , Neutron Research, Material Measurement, and Physical Measurement.

BUREAU OF STANDARDS
In 1901, in response to a bill proposed by Congressman James H. Southard (R, Ohio), the National Bureau of Standards was founded with the mandate to provide standard weights and measures, and to serve as the national physical laboratory for the United States. (Southard had previously sponsored a bill for metric conversion of the United States.) Chart of NBS activities, 1915
Initially conceived as purely a metrology agency, the Bureau of
Standards was directed by
In 1948, financed by the Air Force, the Bureau began design and construction of SEAC , the Standards Eastern Automatic Computer. The computer went into operation in May 1950 using a combination of vacuum tubes and solid-state diode logic. About the same time the Standards Western Automatic Computer , was built at the Los Angeles office of the NBS and used for research there. A mobile version, DYSEAC , was built for the Signal Corps in 1954.
Due to a changing mission, the "National Bureau of Standards" became
the National Institute of Standards and
Following 9/11, NIST conducted the official investigation into the collapse of the World Trade Center buildings.
NIST, known between 1901 and 1988, as the National Bureau of Standards (NBS), is a measurement standards laboratory , also known as a National Metrological Institute (NMI), which is a non-regulatory agency of the United States Department of Commerce . The institute's official mission is to:
Promote U.S. innovation and industrial competitiveness by advancing measurement science , standards , and technology in ways that enhance economic security and improve our quality of life . — NIST
NIST had an operating budget for fiscal year 2007 (October 1, 2006 – September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, and it also received $610 million as part of the American Recovery and Reinvestment Act . 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 countries) 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".
The Congress of 1866 made use of the metric system in commerce a
legally protected activity through the passage of
Metric Act of 1866 .
On May 20, 1875, 17 out of 20 countries signed a document known as
the Metric Convention or the Treaty of the Meter, which established

NIST's Boulder laboratories are best known for NIST‑F1 , which houses an atomic clock . NIST‑F1 serves as the source of the nation's official time. From its measurement of the natural resonance frequency of cesium —which defines the second —NIST broadcasts time signals via longwave radio station WWVB near Fort Collins , Colorado, and shortwave radio stations WWV and WWVH , located near Fort Collins and Kekaha, Hawaii , respectively.
NIST also operates a neutron science user facility: the NIST Center for Neutron Research (NCNR). The NCNR provides scientists access to a variety of neutron scattering instruments, which they use in many research fields (materials science, fuel cells, biotechnology, etc.).
The SURF III Synchrotron Ultraviolet Radiation Facility is a source
of synchrotron radiation , in continuous operation since 1961. SURF

MEASUREMENTS AND STANDARDS
As part of its mission, NIST supplies industry, academia, government, and other users with over 1,300 Standard Reference Materials (SRMs). These artifacts are certified as having specific characteristics or component content, used as calibration standards for measuring equipment and procedures, quality control benchmarks for industrial processes, and experimental control samples.
NIST publishes the Handbook 44 each year after the annual meeting of the National Conference on Weights and Measures (NCWM). Each edition is developed through cooperation of the COMMITTEE ON SPECIFICATIONS AND TOLERANCES of the NCWM and the WEIGHTS AND MEASURES DIVISION (WMD) of the NIST. The purpose of the book is a partial fulfillment of the statutory responsibility for "cooperation with the states in securing uniformity of weights and measures laws and methods of inspection".
NIST has been publishing various forms of what is now the Handbook 44 since 1918 and began publication under the current name in 1949. The 2010 edition conforms to the concept of the primary use of the SI (metric) measurements recommended by the Omnibus Foreign Trade and Competitiveness Act of 1988.

NIST is developing government-wide identity document standards for federal employees and contractors to prevent unauthorized persons from gaining access to government buildings and computer systems.
WORLD TRADE CENTER COLLAPSE INVESTIGATION
In 2002 the National Construction Safety Team Act mandated NIST to conduct an investigation into the collapse of the World Trade Center buildings 1 and 2 and the 47-story 7 World Trade Center. The "World Trade Center Collapse Investigation", directed by lead investigator Shyam Sunder, covered three aspects, including a technical building and fire safety investigation to study the factors contributing to the probable cause of the collapses of the WTC Towers (WTC 1 and 2) and WTC 7. NIST also established a research and development program to provide the technical basis for improved building and fire codes, standards, and practices, and a dissemination and technical assistance program to engage leaders of the construction and building community in implementing proposed changes to practices, standards, and codes. 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.
NIST works in conjunction with the Technical Guidelines Development Committee of the Election Assistance Commission to develop the Voluntary Voting System Guidelines for voting machines and other election technology. Further information: Certification of voting machines
Four scientific researchers at NIST have been awarded Nobel Prizes
for work in physics :
William D. Phillips in 1997,
Eric A. Cornell in
John L. Hall in 2005 and
David J. Wineland in 2012, which is the
largest number for any US government laboratory. All four were
recognized for their work related to laser cooling of atoms, which is
directly related to the development and advancement of the atomic
clock. In 2011,

CONTROVERSIAL BACKDOORED NIST STANDARD
NIST responded to the allegations, stating that "NIST works to
publish the strongest cryptographic standards possible" and that it
uses "a transparent, public process to rigorously vet our recommended
standards". The agency stated that "there has been some confusion
about the standards development process and the role of different
organizations in it...The
