As part of their main mission, NIST certifies and provides standard reference materials (SRM). SRMs are used to perform instrument calibrations, verify accuracy of specific measurements and to support development of new measurement methods. SRMs are also used to support measurement traceability in the United States.

The main purpose of standard reference materials is to provide a well characterized material with a measured value and its associated uncertainty for some 

Our reference materials are traceable to primary standards from NIST (U.S.) and/or PTB (Germany) as documented in the comprehensive, batch-specific 

Quantification and NIST Traceability of Micromatter Thin Film Standards for XRF Analysis Micromatter standards are NIST Traceable Reference MaterialsTM.

The SRM is certified by NIST against primary gas standards which are prepared by NIST and which have undergone rigorous validation both at NIST and internationally. The SRM is then sold to users through the NIST's SRM Program. The NTRM program is a collaboration between NIST and a specialty gas company to certify a production lot of gas standards.

Standard Reference Materials® Description: 1) NIST supports accurate and compatible measurements by certifying and providing over 1100 Standard Reference Materials (SRMs)with well-characterized composition or properties, or both. 1989 - Certification of reference materials - General and statistical principles. 2) ISO Guide 31: 2000

NIST Standard Reference Materials (SRMs) are key tools for verifying important measurement results, developing new measurement methods, and providing users

01/04/1990 · The certified concentration for recombinant HSA was determined using a higher-order reference measurement procedure [ 4] calibrated with amino acid certified reference materials. The uncertainty provided value is an expanded uncertainty about the mean to cover the measurand, consistent with the ISO/JCGM Guide [ 3].

The certified mass fractions delivered by Standard Reference Material (SRM) 1270a are intended primarily for use in validation of chemical and instrumental methods of analysis for element contents of iron and steel alloys. They can be used to validate value assignment of a laboratory's in-house reference materials.
