NIST supports accurate and compatible measurements by certifying and providing more than 1300 Standard Reference Materials® with well-characterized composition or properties, or both. 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.
For more than 50 years, NIST has developed and distributed Standard Reference Data. Search the NIST Data Gateway and view our list of more than 70 NIST web sites dedicated to Standard Reference Data including the NIST Chemistry WebBook, the Atomic Spectra Database, and the X-ray Photoelectron Spectroscopy Database.
NIST scientists, in collaboration with external stakeholders, has developed and published protocols for nanomaterial measurements since 2007. These protocols are downloadable and have citable DOIs. They are published under the NIST Special Publication series 1200.
