NIST Standard Reference materials (SRMs) are used by industry, government and academia to ensure the highest quality measurements. This catalog lists over 1300 individual reference materials produced and sold, by NIST, each with carefully assigned values for chemical composition and physical properties.SRMs find use in calibrating instruments and in assuring the long-term integrity of quality assurance programs. They are also key mechanisms for verifying important measurement results and in developing new measurement methods. SRMs provide users with tools to assist in establishing traceability to measurement results to NIST.Each SRM comes carefully packaged with documentation containing assigned values with stated uncertainties and a material safety data sheet, if applicable. Details on use, stability, and NIST analytical methods are also included.
