Certified Reference Materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments. A certified reference material is a particular form of measurement standard. Reference materials are particularly important

SRMs are unique to RMs and CRMs because they are RMs that also meet certification criteria outlined by NIST. Certificates are issued by NIST to report the characteristics of SRMs, providing scientists are researchers with the necessary information to use the material correctly. NIST outlines that SRMs are developed and used for three main purposes.

We can supply Certified Reference Materials from the world's leading National Measurement Institutes (NMIs). LGC is the UK National Measurement Laboratory

The reference material hierarchy includes five major quality grades, from national metrology and other primary standards to Certified Reference Materials (CRMs), Reference Materials (RMs), Analytical Standards, and research grade or research chemicals. Level of certification and traceability requirements increase for each higher level.

DISTRIBUTION OF NIST STANDARD REFERENCE MATERIALS In order to facilitate the world-wide distribution of its Standard Reference Materials (SRMs), the National Institute of Standards and Technology (NIST) has established a licensed distributor program.

Standard Reference Material any one of the substances (materials) with precisely known and officially certified values of variables peculiar to a given substance. Standard reference materials quantitatively characterize the content of isotopes, elements, and compounds.

Physical Standards and Reference Materials. Physical standards and reference materials are substances or materials produced in a controlled environment that are used as a "calibrator" to produce additional substances or materials (e.g., materials of documented purity certified by an analytical laboratory or other noncommercial establishment).
