Length and dimensional measurements at NIST.(National Institute of Standards and Technology)
January 1, 2001... This paper discusses the past, present, and future of length and dimensional measurements at NIST. It covers the evolution of the SI unit of length through its three definitions and the evolution of NBS-NIST dimensional measurement from early...

The kilogram and measurements of mass and force.
January 1, 2001... This paper describes the facilities, measurement capabilities, and ongoing research activities in the areas of mass and force at the National Institute of Standards and Technology (NIST). The first section of the paper is devoted to mass...

Primary atomic frequency standards at NIST.(National Institute of Standards and Technology)
January 1, 2001... The development of atomic frequency standards at NIST is discussed and three of the key frequency-standard technologies of the current era are described. For each of these technologies, the most recent NIST implementation of the particular type...

The ampere and electrical standards.
January 1, 2001... This paper describes some of the major contributions to metrology and physics made by the NIST Electricity Division, which has existed since 1901. It was one of the six original divisions of the National Bureau of Standards. The Electricity...

The Kelvin and temperature measurements.
January 1, 2001... The International Temperature Scale of 1990 (ITS-90) is dcfined from 0.65 K upwards to the highest temperature measurable by spectral radiation thermometry, the radiation thermometry being based on the Planck radiation law. When it was...

The candela and photometric and radiometric measurements.
January 1, 2001... The national measurement system for photometric and radiometric quantities is presently based upon techniques that make these quantities traceable to a high-accuracy cryogenic radiometer. The redefinition of the candela in 1979 provided the...

Materials research with neutrons at NIST.(National Institute of Standards and Technology)
January 1, 2001... The NIST Materials Science and Engineering Laboratory works with industry, standards bodies, universities, and other government laboratories to improve the nation's measurements and standards infrastructure for materials. An increasingly...

In Situ burning of oil spills.
January 1, 2001... For more than a decade NIST conducted research to understand, measure and predict the important features of burning oil on water. Results of that research have been included in nationally recognized guidelines for approval of intentional...

Statistics and measurements.
January 1, 2001... For more than 50 years, the Statistical Engineering Division (SED) has been instrumental in the success of a broad spectrum of metrology projects at NBS/NIST. This paper highlights fundamental contributions of NBS/NIST statisticians to...

Mathematics and measurement.
January 1, 2001... In this paper we describe the role that mathematics plays in measurement science at NIST. We first survey the history behind NIST's current work in this area, starting with the NBS Math Tables project of the l930s. We then provide examples of...

NIST mechanisms for disseminating measurements.(National Institute of Standards and Technology)
January 1, 2001... The national responsibilities assigned to the National Bureau of Standards (NBS) early in the last century for providing measurement assistance and service are carried out today by the four programs that comprise the National Institute of...

Information technology measurement and testing activities at NIST.(National Institute of Standards and Technology)
January 1, 2001... Our high technology society Continues to rely more and more upon sophisticated measurements, technical standards, and associated testing activities. This was true for the industrial society of the 20th century and remains true for the...
