ISO 33407:2024

This document indicates the requirements of ISO 17034 and provides specific recommendations on technical aspects to be considered for the production of certified reference materials (CRMs) for pure organic substances, which laboratories use to calibrate equipment and measurement procedures, as well as to establish the metrological traceability of the respective results. These recommendations are only relevant for CRMs that include organic compounds whose structures are specifically defined, polymeric materials being excluded. In this document, reference to an MRC is limited to certified reference materials for pure organic substances, including candidate materials, unless otherwise stated.
