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.

Standard Reference Materials® Chemical Name: RM, SRM, CRM, NIST, ARD, ERM. 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. These materials are used to perform instrument calibrations in units as part of

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).

The IAEA Environment Laboratories produce certified reference materials for the measurement of radionuclides, trace elements and organic contaminants.

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

A standard reference material (SRM) as defined by NIST “is a material or artifact that has had one or more of its property values certified by a technically valid procedure, and is
