From forward: Every laboratory in this country is a valuable national resource. Along with the people who work in these facilities, U.S. laboratories constitute the basic foundation of this country's scientific and industrial strength. As the nation's foremost science and engineering measurement laboratory, the National Bureau of Standards has some of the premier research and testing facilities in the United States, and several of our laboratories are unequaled anywhere in the world. Bureau scientists and engineers use these special facilities to pursue the measurement-related work that U.S. science and industry need to grow and prosper. This brochure highlights only a small number of the special facilities available at NBS and provides information about their availability for collaborative or independent research and testing.
