Tm he National Bureau of Standards' was established by an act of Congress on March 3, 1901. The Bureau's overall goal is facilitate jla to strengthen and advance the nation's science and technology and their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau's technical work is performed by the National Measurement Laboratory, the National Engineering Laboratory, the Institute for Computer Sciences and Technology, and the Institute for Materials Science and Engineering The National Measurement Laboratory Provides the national system of physical and chemical measurement; • Basic Standards^ coordinates the system with measurement systems of other nations and • Radiation Research furnishes essentiaJ services leading to accurate and uniform physical and • Chemical Physics chemical measurement throughout the Nation's scientific community, in- • Analytical Chemistry dustry, and commerce; provides advisory and research services to other Government agencies; conducts physical and chemical research; develops, produces, and distributes Standard Reference Materials; and provides calibration services. The Laboratory consists of the following centers: The National Engineering Laboratory Provides technology and technical services to the public and private sectors to Applied Mathematics address national needs and to solve national problems; conducts research in Electronics and Electrical engineering and applied science in support of these efforts; builds and main- Engineering"^ tains competence in the necessary disciplines required to carry out this Manufacturing Engineering research and technical service; develops engineering data and measurement Building Technology capabilities; provides engineering measurement traceability services; develops Fire Research test methods and proposes engineering standards and code changes; develops Chemical Engineering^ and proposes new engineering practices; and develops and improves mechanisms to transfer results of its research to the ultimate user. The Laboratory consists of the following centers: The Institute for Computer Sciences and Technology Conducts research and provides scientific and technical services to aid Programming Science and Federal agencies in the selection, acquisition, application, and use of com- Technology puter technology to improve effectiveness and economy in Government Computer Systems operations in accordance with Public Law 89-306 (40 U.S.C. 759), relevant Engineering Executive Orders, and other directives; carries out this mission by managing the Federal Information Processing Standards Program, developing Federal ADP standards guidelines, and managing Federal participation in ADP voluntary standardization activities; provides scientific and technological ad- visory services and assistance to Federal agencies; and provides the technical foundation for computer-related policies of the Federal Government. The In- stitute consists of the following centers: The Institute for Materials Science and Engineering Conducts research and provides measurements, data, standards, reference Inorganic Materials materials, quantitative understanding and other technical information funda- Fracture and Deformation"^ mental to the processing, structure, properties and performance of materials; Polymers addresses the scientific basis for new advanced materials technologies; plans Metallurgy research around cross-country scientific themes such as nondestructive Reactor Radiation evaluation and phase diagram development; oversees Bureau-wide technical programs in nuclear reactor radiation research and nondestructive evalua- tion; and broadly disseminates generic technical information resulting from its programs. The Institute consists of the following Divisions: 'Headquarters and Laboratories at Gaithersburg, MD, unless otherwise noted; mailing address Gaithersburg, MD 20899. "Some divisions within the center are located at Boulder, CO 80303 'Located at Boulder, CO, with some elements at Gaithersburg, MD.
