Green Tea standard reference. Certified reference materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments. [1] A certified reference material is a particular form of measurement standard.
Cerilliant is accredited to ISO Guide 34 & ISO/IEC 17025 and certified to ISO 13485 and ISO 9001:2008. [2] Formerly known as the Analytical Reference Materials Division of Radian International, Cerilliant was founded in 1980 and began producing chemical reference standards to address the needs of the emerging environmental testing industry.
National Accreditation Board for Testing and Calibration Laboratories (NABL) provides accreditation to Conformity Assessment Bodies (Laboratories) in India.NABL Schemes include Accreditation (Recognition) of Technical competence of testing, calibration, medical testing laboratories, Proficiency testing providers (PTP) & Reference Material Producers (RMP) for a specific scope following ISO/IEC ...
Since 2011, the reference material for the isotopic composition of natural mercury, NIMS-1, is basis for the standard atomic weight of mercury [2]. NRC produces certified reference materials of biological tissues, isotopic standards, natural waters, sediments, supplements, and natural health products.
Working standards and certified reference materials used in commerce and industry have a traceable relationship to the secondary and primary standards. Working standards are expected to deteriorate, and are no longer considered traceable to a national standard [ 6 ] after a time period or use count expires.

The manufacture of the material involves controlled crystallization. [2] NASA classifies it as a glass-ceramic product. [7] After about 30 years of informal use as a standard in high-heat (≥1000 °C) applications, Pyroceram 9606 was approved by NIST as a certified reference material for thermal conductivity measurements.
