Standard Reference Materials

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.

Standard Reference Data

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.

Nano-Measurement Protocols

NIST has been developing protocols for measurements of nanomaterials since 2007; some these protocols have been published in a series of NIST Special Publications (SPs) with citable DOI names to provide persistent identification.


Chemistry WebBook

The NIST Chemistry WebBook provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data Program.
