National Institute of Standards and Technology

The National Institute of Standards and Technology (NIST) is a physical sciences laboratory and non-regulatory agency of the U.S. Department of Commerce that develops and maintains the nation's measurement standards, advances measurement science, and coordinates the federal government's use of technical standards. Founded by Congress on March 3, 1901 as the National Bureau of Standards (NBS), it was renamed NIST in 1988 to reflect an expanded mission of promoting U.S. innovation and industrial competitiveness.¹^•²

History

Congress established the National Bureau of Standards to address a measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals; at the time there were, for example, eight different "authoritative" values of the gallon in use.¹^•² The agency's functions predate its founding: the Office of Weights and Measures, still NIST's oldest office, traces its charge to "fix the standard of weights and measures" in Article I, Section 8 of the U.S. Constitution, and a June 14, 1836 act of Congress directed distribution of uniform standards to the states.¹⁰

The founding director was Samuel W. Stratton, who served from 1901 to 1922 and whose advocacy won over a reluctant Congress.⁴^•¹¹ The name changed several times: Bureau of Standards in 1903, National Bureau of Standards again in 1934, and National Institute of Standards and Technology in 1988 under the Omnibus Trade and Competitiveness Act (P.L. 100-418).¹¹^•² New radio testing and cryogenics facilities led to the Boulder, Colorado laboratories, which opened in September 1954 with a dedication address by President Eisenhower.⁴

Research at the laboratories has produced work recognized far beyond metrology. Experiments performed at NIST in 1956 by Ernest Ambler and colleagues confirmed the parity-violation prediction of Chen Ning Yang and Tsung Dao Lee, who won the 1957 Nobel Prize in Physics. The Joint Institute for Laboratory Astrophysics, now JILA, was founded in 1962 as a partnership between the University of Colorado Boulder and NIST, and its researchers later created the Bose-Einstein condensate and developed the laser frequency comb.⁴

The national measurement institute

As the U.S. National Measurement Institute, NIST maintains the national measurement standards, realizes the units of the International System of Units (SI), and disseminates accurate measurements to industry, academia, and consumers by comparing users' standards against its primary standards.³ Primary standards maintained at NIST include the F1 and F3 atomic clocks, which serve as the basis for civilian time in the United States; the Kibble balance, which underpins mass measurements under the modern definition of the kilogram; and Josephson junction devices for the volt.¹² The WWVB radio station, relocated to Fort Collins, Colorado, in 1963, synchronizes radio-controlled clocks across most of North America with NIST's atomic clock in Boulder.⁴

Metrological traceability. Under NIST's policy, metrological traceability is a characteristic of a measurement result that allows it to be linked to a reference via an unbroken, documented series of calibrations, with every link adding to the measurement uncertainty. NIST assures traceability to the SI only for results it provides directly or through an official NIST program, and it emphasizes that traceability alone does not guarantee fitness for purpose, which also requires uncertainty small enough for the intended use.¹³ Calibration services span dimensional, electromagnetic, and other quantities; the Frequency Measurement and Analysis Service, for example, calibrates quartz, rubidium, and cesium frequency standards at an uncertainty of ±5 × 10⁻¹³ per day.¹⁴

Quality and international recognition. The NIST Quality System for Measurement Services is based on ISO/IEC 17025 and incorporates ISO 17034, ISO/IEC 17043, and ISO/TS 8000 as applicable; it satisfies the requirements of the CIPM Mutual Recognition Arrangement (MRA), the framework through which national metrology institutes demonstrate international equivalence of their standards and certificates, and has been recognized as conformant by the Inter-American Metrology System and the Joint Committee of the Regional Metrology Organizations and the BIPM.¹⁵^•¹⁶

Products and services

NIST supports accurate measurement through several product lines. Standard Reference Materials (SRMs) are well-characterized materials certified for composition or properties, sold to laboratories and manufacturers to verify their measurements; NIST certifies and provides over 1200 of them.⁶^•⁷ Standard Reference Instruments are NIST-designed devices, such as ozone monitors and voltage standards, that customers purchase as a basis for traceable measurements.⁷ Standard Reference Data are critically evaluated datasets, from structural steel properties to comprehensive chemistry databases, and the National Voluntary Laboratory Accreditation Program (NVLAP) provides third-party accreditation of testing and calibration laboratories.⁷

Documentary standards. Alongside physical measurement standards, NIST works on documentary standards, written agreements specifying test methods, procedures, and product characteristics. Under the National Technology Transfer and Advancement Act (NTTAA), NIST coordinates federal, state, and local documentary standards and conformity assessment activities, and federal agencies must use voluntary consensus standards in procurement and regulation unless impractical, reporting exceptions to the Office of Management and Budget through NIST under OMB Circular A-119.¹⁷^•¹⁸^•¹⁹ NIST staff participate in more than 1500 standards-writing activities, and the Office of Weights and Measures publishes the NIST Handbooks, consensus documentary standards for legal metrology used in commerce.³^•¹⁷

Cybersecurity and AI frameworks

NIST's Information Technology Laboratory develops cybersecurity standards and guidelines for federal agencies and U.S. industry.⁵ Its best-known product in this area is the Cybersecurity Framework (CSF), first released in 2014 following a presidential executive order. Version 2.0, released February 26, 2024, was the framework's first major update and expanded its scope from critical infrastructure to organizations of all types and sizes, adding a sixth core function, Govern, alongside Identify, Protect, Detect, Respond, and Recover.²⁰ NIST is not a regulatory agency, and most organizations use the CSF voluntarily, although Executive Order 13800 made it mandatory for U.S. federal agencies.²¹

The agency also leads U.S. work on AI measurement. In an interview with the Associated Press, NIST described its role in the AI risk management framework and the associated safety consortium as advancing the measurement science and standards needed for evaluating AI systems, including evaluations of the kind it had previously performed for face recognition algorithms, while stating that NIST itself does not conduct red-teaming and remains a neutral, non-regulatory agency.²²

Manufacturing Extension Partnership

The Hollings Manufacturing Extension Partnership (MEP), created by the Technology Competitiveness Act of 1988 and renamed for Senator Ernest Hollings by the Consolidated Appropriations Act of 2005, is a nationwide network of centers serving small and medium-sized U.S. manufacturers.⁸^•²³ The program comprises nearly 1,400 manufacturing advisors at more than 450 service locations across the states and Puerto Rico.⁸ It is a cost-share partnership: federal appropriations pay one half, with state and local governments, private entities, and client fees covering the balance. A GAO review found that in fiscal year 2010 client fees paid by manufacturers totaled $97.1 million and were the largest source of nonfederal contributions, and that 60 centers operated under annual cooperative agreements with NIST.⁸^•²⁴ By its 30th anniversary in 2018, MEP reported working with 94,033 manufacturers since 1988, associated with $111.3 billion in sales, $18.8 billion in cost savings, and 985,317 jobs created or retained.²⁵

Baldrige Performance Excellence Program

The Baldrige Program administers the Malcolm Baldrige National Quality Award, created by Congress in 1987 after the death of Commerce Secretary Malcolm Baldrige and presented at the presidential level. Each year, as many as 18 awards may be bestowed, spanning six categories of eligibility: manufacturing, service, small business, education, health care, and nonprofit organizations.⁴^•²⁶ Beginning with the 2026 award cycle, most operational responsibilities transfer to two private-sector organizations, the Alliance for Performance Excellence and the Baldrige Foundation, while NIST and the Department of Commerce retain ownership and oversight of the Baldrige Excellence Framework and the award process.⁹

Economic role

NIST has commissioned economic studies of its impact on industry; according to a NIST director's testimony, 19 such studies documented an average direct return to the economy of $44 for every $1 spent by NIST, with individual projects ranging from a benefit-to-cost ratio of about 113 to one for standard reference materials for sulfur content in fuels to about four to one for chemical and thermodynamic datasets for alternative refrigerants.²⁷ Weights and measures regulation, coordinated through NIST's Office of Weights and Measures with the states, is estimated to affect commercial transactions involving approximately 45% of 2022 U.S. gross domestic product.²⁸
