TO THE ACCEPTOR

The following statements answer the usual questions arising in connection with the acceptance of a Voluntary Product Standard and its significance:

1. Enforcement—Voluntary Product Standards contain requirements which are established by mutual consent of those concerned in accordance with the Procedures for the Development of Voluntary Product Standards published by the Department of Commerce (15 CFR Part 10, as amended, May 28, 1970). The standards provide a common basis of understanding among producers, distributors, and users or consumers. The National Bureau of Standards has no regulatory power in the enforcement of the provisions of voluntary standards, but since these standards represent the will of the interested gro ps as a whole, their provisions soon become established as trade customs and become effective when the standards are referenced in sales contracts, procurement specifications, government regulations, and the like.

2. The Responsibility of the Acceptor—The purpose of Voluntary Product Standards is to establish, for specific items, nationally recognized sizes, grades, material requirements, or performance criteria. The benefits that result from these standards will be in direct proportion to general recognition and actual use of the standards. Instances will occur when it may be necessary to deviate from a standard. The signing of an acceptance does not preclude such departures. The acceptor's signature, however, indicates an intention to follow the standard, where practicable, in the production, distribution, or use and consumption of the product in question.

Gentlemen:

We are primarily engaged in the following segment of the industry:

(Please check only one.) O Production

o Use/consumption Distribution

o General Interest We believe that this Voluntary Product Standard constitutes a useful standard of practice, and we plan to use it as far as practicable. However, we reserve the right to depart from the standard as we deem advisable.

We understand, of course, that only those products which actually conform to the standard in all respects may be represented as conforming thereto. Signature of authorized officer

NATIONAL BUREAU OF STANDARDS

The National Bureau of Standards' 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 measure-
ment 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 consists of the Institute for Basic Standards, the Institute for Materials
Research, the Institute for Applied Technology, the Center for Computer Sciences and
Technology, and the Office for Information Programs.
THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the
United States of a complete and consistent system of physical measurement; coordinates
that system with measurement systems of other nations, and furnishes essential services
leading to accurate and uniform physical measurements throughout the Nation's scien-
tific community, industry, and commerce. The Institute consists of a Center for Radia-
tion Research, an Office of Measurement Services and the following divisions:

Applied Mathematics—Electricity-Heat-Mechanics Optical Physics—Linac
Radiation?—Nuclear Radiation-Applied Radiation—Quantum Electronics—
Electromagnetics3—Time and Frequency3—Laboratory Astrophysics—Cryo-

genics3. THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measurement, standards, and data on the properties of well-characterized materials needed by industry, commerce, educational institutions, 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 and the following divisions:

Analytical Chemistry-Polymers—Metallurgy-Inorganic Materials—Reactor

Radiation-Physical Chemistry. THE INSTITUTE FOR APPLIED TECHNOLOGY provides technical services to promote the use of available technology and to facilitate technological innovation in industry and Government; cooperates with public and private organizations leading to the development of technological standards (including mandatory safety standards), codes and methods of test; and provides technical advice and services to Government agencies upon request. The Institute also monitors NBS engineering standards activities and provides liaison between NBS and national and international engineering standards bodies. The Institute consists of the following divisions and offices: Engineering Standards Services-Weights and Measures—Invention

and Innovation—Product Evaluation Technology-Building Research—Electronic Technology-Technical Analysis—Measurement Engineering-Office of Fire

Programs. THE CENTER 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 within the executive branch for the development of Federal standards for automatic data processing equipment, techniques, and computer languages. The Center consists of the following offices and divisions:

Information Processing Standards—Computer Information Computer Services

-Systems Development Information Processing Technology. THE OFFICE FOR INFORMATION PROGRAMS promotes optimum dissemination and accessibility of scientific information generated within NBS and other agencies of the Federal Government; promotes the development of the National Standard Reference Data System and a system of information 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, and directs the public information activities of the Bureau. The Office consists of the following organizational units:
