UNIV. of ARIZONA J^ Standard X-ray diffraction powder pattern Tr> C 13.44: 25/S6C.14 MONOGRAPH & 25 SECTION 14 CO \ J 3 9001 90011 2817 U.S. DEPARTMENT OF COMMERCE/ National Bureau of Standards Standard X-ray Diffraction Powder Patterns NATIONAL BUREAU OF STANDARDS The National Bureau of Standards 1 was established by an act of Congress March 3, 1901. The Bureau©s overall goal is to strengthen and advance the Nation©s science and technology and facilitate 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 pro mote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, the Office for Information Programs, and the Office of Experimental Technology Incentives Program. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consist ent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essen tial services leading to accurate and uniform physical measurements throughout the Nation©s scientific community, industry, and commerce. The Institute consists of the Office of Measurement Services, and the following center and divisions: Applied Mathematics Electricity Mechanics Heat Optical Physics Center for Radiation Research Lab oratory Astrophysics 2 Cryogenics* Electromagnetics 2 Time and Frequency*. TOE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measure ment, standards, and data on the properties of well-characterized materials needed by industry, commerce, educational insti tutions, and Government; provides advisory and research services to other Government agencies; and develops, produces, and distributes standard reference materials. The Institute consists of the Office of Standard Reference Materials, the Office of Air and Water Measurement, and the following divisions: Analytical Chemistry Polymers Metallurgy Inorganic Materials Reactor Radiation Physical Chemistry. THE INSTITUTE FOR APPLIED TECHNOLOGY provides technical services developing and promoting the use of avail able technology; cooperates with public and private organizations in developing technological standards, codes, and test meth ods; and provides technical advice services, and information to Government agencies and the public. The Institute consists of the following divisions and centers: Standards Application and Analysis Electronic Technology Center for Consumer Product Technology: Product Systems Analysis; Product Engineering Center for Building Technology: Structures, Materials, and Safety; Building Environment; Technical Evaluation and Application Center for Fire Research; Fire Science; Fire Safety Engineering. THE INSTITUTE FOR COMPUTER SCIENCES AND TECHNOLOGY conducts research and provides technical services designed to aid Government agencies in improving cost effectiveness in the conduct of their programs through the selection, acquisition, and effective utilization of automatic data processing equipment; and serves as the principal focus wthin the exec utive branch for the development of Federal standards for automatic data processing equipment, techniques, and computer languages. The Institute consist of the following divisions: Computer Services Systems and Software Computer Systems Engineering Information Technology. THE OFFICE OF EXPERIMENTAL TECHNOLOGY INCENTIVES PROGRAM seeks to affect public policy and process to facilitate technological change in the private sector by examining and experimenting with Government policies and prac tices in order to identify and remove Government-related barriers and to correct inherent market imperfections that impede the innovation process. THE OFFICE FOR INFORMATION PROGRAMS promotes optimum dissemination and accessibility of scientific informa tion generated within NBS; promotes the development of the National Standard Reference Data System and a system of in formation analysis centers dealing with the broader aspects of the National Measurement System; provides appropriate services to ensure that the NBS staff has optimum accessibility to the scientific information of the world. The Office consists of the following organizational units: Office of Standard Reference Data Office of Information Activities Office of Technical Publications Library Office of International Standards Office of International Relations. 1 Headquarters and Laboratories at Gaithersburg, Maryland, unless otherwise noted; mailing address Washington, D.C. 20234. 3 Located at Boulder, Colorado 80302.
