View source for Certified reference material

A reference material characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty, and a statement of metrological traceability. Certified reference materials are traceable to international standards with a known uncertainty and therefore can be used to address all aspects of bias (method, laboratory, and within-laboratory) simultaneously, assuming that there is no matrix mismatch. {{stub}} [[category:definitions]]
