National Institute of Standards and Technology (NIST) Standard Reference Materials® (SRMs®) are used by industry, government and academia to ensure the highest quality measurements. A new catalog lists over 1100 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 of 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.
The new SRM catalog and pricing are available in hard copy, CD and online at www.nist.gov/srm
