SRMs are unique to RMs and CRMs because they are RMs that also meet certification criteria outlined by NIST. Certificates are issued by NIST to report the characteristics of SRMs, providing scientists are researchers with the necessary information to use the material correctly. NIST outlines that SRMs are developed and used for three main purposes.
