Twice each calendar year SRMs may be re-priced taking into account the updates for overhead and surcharge rates as determined by NIST and the Department of Commerce. On these occasions (approximately January and July) SRM prices are adjusted to reflect these changes. The next price change is scheduled on or about January 23, 2026.
The calibration services of the National Institute of Standards and Technology (NIST) are designed to help the makers and users of precision instruments achieve the highest possible levels of measurement quality and productivity.
For over 50 years, NIST has developed and distributed Standard Reference Data in Chemistry, Engineering, Fluids and Condensed Phases, Material Sciences, Mathematical and Computer Sciences and Physics.
NIST supports accurate measurements by providing Standard Reference Materials® with well-characterized composition, or properties, or both.
