The article describes an approach to establishing the metrological traceability of reference materials adopted by TC 1.12 Reference Materials of the Euro-Asian Cooperation of National Metrological Institutions (COOMET). Specific examples of the production of COOMET reference materials are given. Approaches to demonstrating metrological traceability of reference materials depending on the method of their characterization are considered, i.e., the application of state measurement standards, interlaboratory experiments, as well as primary reference measurement procedures for characterizing reference materials when no state standards for measurement units are available.
