Giới thiệu chung:
NIST-Viện Tiêu chuẩn và Kĩ thuật Quốc gia USA cung cấp hơn 1300 chất chuẩn SRM # (Standard Reference Materials).
Industry, academia, and government use NIST SRMs to facilitate commerce and trade and to advance research and development. Presently NIST SRMs are currently available for use in areas such as industrial materials production and analysis, environmental analysis, health measurements and basic measurements in science and metrology. NIST SRMs are also one mechanism for supporting measurement traceability in the United States.
Each NIST Standard Reference Material® is supplied with a Certificate of Analysis and a Materials Safety Data Sheet, when applicable. In addition, NIST has published many articles and practice guides that describe the development, analysis and use of SRMs.
