Excerpt from Standard Reference Materials 1973 Catalog

The National Bureau of Standards presently has available more than 800 Standard Reference Materials. It is also working on the development of about 150 new ones and has on hand requests for the preparation of many others. The requests have always far exceeded the Bureau's capacity to produce and certify these materials.

One of the functions of the National Bureau of Standards is to develop, produce, and distribute Standard Reference Materials that provide a basis for comparison of measurements on materials and aid in the control of production processes in industry: To help carry out this function, the Office of Standard Reference Materials evaluates the requirements of science, industry, and government for carefully characterized reference materials, and directs their production and distribution. Emphasis is given to providing nbs Standard Reference Materials (a) where attainment of needed accuracy of analysis or accuracy of measurement of characteristics is not economically or technically feasible elsewhere, and where such accuracy is generally important to users, (b) where industry-wide stand ards for commerce are needed from a neutral supplier who is not otherwise available, and (c) where continuing availability of highly characterized material from a common source is important to science, industry, or government.

The National Bureau of Standards recognized and had responded to the need for broadening the present program on reference materials to include all types of well-characterized materials that can be used to calibrate a measurement system or to produce scientific data that can be readily referred to a common base. With this broadening, however, it still remains apparent that the demand for new Standard Reference Materials will continue to greatly exceed the Bureau's capacity for develop ment. Therefore, requests for new Standard Reference Materials that will have limited use and for which the need is not very great will have to be deferred in favor of requests clearly showing a critical need. For the purpose of determining which requests are to receive top priority, the Na tional Bureau of Standards will need, and will rely heavily upon, the information supplied by industry, either through its own representatives or through interested committees, such as those of the American Society for Testing and Materials, the American National Standards Institute, the International Organization for Standardization, etc.
