SRM (Standard Reference Material)

SRM (Standard Reference Material) - these are registered NIST products, only NIST can provide them. Most international NMIs use NIST SRMs to achieve their traceability to the SI, making NIST SRMs uniquely crucial and valuable internationally.

  • These are the standards that NIST is responsible for tracing back to the SI to ensure harmony in measurement- these are also the standards that we use for comparison testing to establish our traceability to NIST.
