A standard reference material (SRM) as defined by NIST “is a material or artifact that has had one or more of its property values certified by a technically valid procedure, and is accompanied by, or traceable to, a certificate or other documentation which is issued by NIST… Standard reference materials are…manufactured according to strict specifications and certified by NIST for one or more quantities of interest.
SRMs represent one of the primary vehicles for disseminating measurement technology to industry.”
