Excerpt from The National Bureau of Standards In 1901 the National Bureau of Standards was established by Congress, with broad functions, consistent with the modern view of standards and standard measurements. In 10 years the bureau has grown to occupy an important place in the Government, having 286 employees, four laboratory buildings in Washington, and branch laboratories in Pittsburgh and Northampton, Pa., and in Charleston, S. C. The main laboratories are located in the rthwestern suburbs of Washington at an elevation of 350 feet above the Potomac River, on a natural hill site of about 8 acres - a locality admirably suited to its work. A fifth building is under construction for the electrical work of the bureau. As rapidly as consistent with its standard of work the bureau has taken up the following functions as prescribed in its organic act: (1) The custody of the standards, which involves their care and preservation and also the intercomparisons and researches necessary to maintain the constancy of such standards as are liable to change. (2) The comparisons of standards for States, municipalities, institutions, and the general public - comprising standards used in commerce, manufacturing, and science, assuring to the public accuracy at its source - in the factory and the works laboratory. (3) The construction of standards as required by scientific or technical progress. New standards are constructed at the bureau upon the basis of the best available data, in some cases upon researches at the bureau and sometimes by international agreement. (4) Standardization of measuring apparatus for manufacturers as a test of their output, or for the user that he may verify instruments or materials independently. (5) Technical research upon problems connected with standards, problems arising constantly in all lines of testing and standardization. Such research facilitates scientific and technical progress, since by refined measurements alone are many of these advances made possible.
