Abstract

Standard Reference Materials (SRMs) are certified reference materials (CRMs) issued under the NIST trademark that are well-characterized using state-of-the-art measurement methods and/or technologies for chemical composition and/or physical properties. Traditionally, SRMs have been the primary tools that NIST (formerly NBS) provides to the user community for achieving measurement quality assurance and traceability to national standards. Each SRM is the result of collaboration between NIST and representatives of science and industry. SRMs are crucial reference points in establishing a comprehensive measurement system for the United States. To SRM users, the selection and proper use of SRMs have become important issues when face with current demands on measurement quality and assurance. As the measurement community has become more global, alternative sources of reference materials or secondary standards must be carefully scrutinize as to their source and traceability hierarchy. This paper covers the NIST certification process; process of selecting appropriate SRMs; SRM traceability hierarchy; SRM maintenance and storage problems; and availability information.
