About
NIST SRMs
NIST supports
accurate and compatible measurements by
certifying and providing over 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.
Industry, academia,
and government use NIST SRMs to facilitate
commerce and trade and to advance research
and development. Presently NIST SRMs are
currently available for use in areas such
as industrial materials production and analysis,
environmental analysis, health measurements
and basic measurements in science and metrology.
NIST SRMs are also one mechanism for supporting
measurement traceability in the United States.
Each NIST
Standard Reference Material® is supplied
with a Certificate of Analysis and a Materials
Safety Data Sheet, when applicable. In addition,
NIST has published many articles and practice
guides that describe the development, analysis
and use of SRMs.
The SRM
Program references a number of definitions in connection
with the production, certification, and
use of its SRMs and RMs. Certain definitions,
adopted for SRM use, are derived from international
guides and standards on reference materials
and measurements while others have been
developed by the SRM Program to describe
those activities unique to NIST operations.
An NTRM (NIST Traceable
Reference Material) is a commercially produced
reference material with a well-defined traceability
linkage to existing NIST standards. This
traceability linkage is established via
criteria and protocols defined by NIST.
Commercial reference materials producers
may affix the NTRM trademark to materials
produced according to these criteria and
protocols.
