Measurement Services Division
Provides customers with the means to obtain NIST Standard Reference Materials®, Calibration Services, and Standard Reference Data. NIST supports accurate and compatible measurements by certifying and providing more than 1,300 of the highest quality and metrological value Standard Reference Materials to industry, academia, and government. These materials are used to perform instrument calibrations in units as part of overall quality assurance programs, to verify the accuracy of specific measurements, and to support the development of new measurement methods.
