THE NATIONAL BLIREAl) OF STANDARDS

KiinctionH and ActivitieH

The funrtions of the National Bureau of Standards are set forth in the Act of Congress, March

3, 1901, as anien<le<l h> Congress in Publi<‘ Law 619, 1950. These include the development and

maintenance of the national standards of measurement and the provision of means and methods

for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials,

devices, and structures; advisory services to Government Agencies on scientific and technical

problems; invention and development of devices to serve special needs of the Government; and the

development of standard practices, codes, and specifications. The work includes basic and applied

research, development, engineering, instrumentation, testing, evaluation, calibration services, and

various consultation and information services. A major portion of the Bureau’s work is performed

for other Government Agencies, particularly the Department of Defense and the Atomic Energy

Commission. The scope of activities is suggested by tbe listing of divisions and sections on the

inside of the back cover.

Reports and Publications

The results of ‘the Bureau's work take the form of either actual equipment and devices or

published papers and reports. Reports are issued to the sponsoring agency of a particular project

or program. Published papers appear either in the Bureau’s own series of publications or in the

journals of professional and scientific societies. The Bureau itself publishes three monthly periodicals, available from the Government Printing Office: The Journal of Research, which presents

complete papers reporting teihnical investigations; the Technical News Bulletin, which presents

summar) and preliminary reports on work in progress; and Basic Radio Propagation Predictions,

which provides data for determining the best frequencies to use for radio communications throughout

the world. There are also five series of nonperiodieal publications: The Applied Mathematics

Series, Cir«-ulars, Handbooks, Building Materials ami Slrm tures Re|>urts, ami ' Misi'ellaneous

Publications.

Information on the Bureau’s |uiblicatioiis can be found in N'BS Cirevdar 160, Publications of

the National Bureau of Standards (*1.25) and its Supplement (*0.75), available from the Superintendent of Documents, Government Printing Ofliee, Washington 25, D. C.

Inquiries regarding the Bureau's reports sboubl be addressed to the Office of Technical Information, National Bureau of Standards. Washingl«»n 25. D. C.
