Certified Reference Materials

Certified reference materials (CRMs) are ‘controls’ or standards used during the analysis and/or quality assurance process of products. Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration. These CRMs typically are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided. Accredited laboratories are required to use CRMs to ensure traceability of their results. The highest order CRMs are usually produced and certified by a primary method and under the jurisdiction of a national metrology body.
