A National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) meets specific certification criteria and is issued with a certificate of analysis that reports the results of its characterization and provides information regarding the appropriate use(s) of the material. An SRM is prepared and used for three main purposes: 1) to help develop accurate methods of analysis; 2) to calibrate measurements systems used to facilitate exchange of goods, institute quality control, determine performance characteristics, or measure a property at the state-of-art limit; and 3) to ensure the long-term adequacy and integrity of measurement quality assurance programs. The National Institute of Standards and Technology (NIST) provides over 1300 different SRMs to industry and academia. Every NIST SRM is provided with a certificate of analysis that gives the official characterization of the material's properties. In addition, supplementary documentation, such as this report, describing the development, analysis, and use of SRMs, is also often provided to ensure effective use of these materials.
