This list of resources gives access to relevant information with respect to certified reference materials (CRMs). Reference materials play a critical role in quality assurance and contribute to the process of establishing traceability of units used to report laboratory results. The use of appropriate reference materials is an important aspect of accreditation to ISO/IEC 17025.
A Certified Reference Material (CRM) is 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.

This document describes how the concept of uncertainty of measurement should be introduced taking into account present state of the art understanding. It is realised that during the course of the implementation of ISO/IEC 17025, suitable sector-specific guidance will be needed. However, the harmonisation of the application of the principles of uncertainty of measurement in testing between different disciplines, industry sectors and economies should remain the main goal. (Proposed revisions are on hold until current revisions of ISO/IEC 17025 and GUM are finalised in relation to this topic.)
