Reference materials

A reference material is a substance or material which is sufficiently homogenous and well established to be used for the calibration of an apparatus, evaluation of a measurement or to validate analytical methods.

In combination with participation in proficiency tests this provides good evidence of internal and external quality control assessment, as required by accreditation bodies.
