Standard Reference Materials

NIST supports accurate and compatible measurements by certifying and providing over 1200 Standard Reference Materials® with well-characterized composition or properties, or both.

The Office of Reference Materials at NIST is rapidly approaching the time of the year where we are required to conduct an annual SRM inventory.  Therefore, our shipping department will not be processing any orders from Wednesday, September 22, 2021 through Thursday, September 30, 2021.  All orders will begin to be shipped on Friday, October 1, 2021.
