From Wikipedia, the free encyclopedia

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.
[1] 
A certified reference material is a particular form of measurement standard
.
Reference materials are particularly important for analytical chemistry and clinical analysis.
[2] 
Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration.
These reference materials are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.

Quality management systems involving laboratory accreditation under national and international accreditation/certification standards such asISO/IEC 17025 require metrological traceability to Certified Reference Materials (where possible) when using reference materials for calibration.[3]
Whilst Certified Reference Materials are preferred where available,[3][4] their availability is limited. Reference Materials that do not meet all the criteria for certified reference materials are more widely available: the principal difference is the additional evidence of metrological traceability and statement of measurement uncertainty provided on the certificate for certified reference materials.[5]
