Reference materials
The National Institute of Standards and Technology (NIST) has released its new, comprehensive Standard Reference Materials Catalog. NIST supplies industry, academia, government, and other users with over 1,300 reference materials of the highest quality and metrological value. These standards are currently available for use in industrial materials production and analysis, environmental analysis, health measurements, and basic measurements in science and metrology. Standard Reference Materials (SRMs) have been used by NIST as vehicles for transferring measurement science and technology, through channels of industry and commerce, to the nation at large.
