This document explains concepts and provides approaches to the following aspects of the production of reference materials (RMs):
the establishment of the metrological traceability of certified values.
The guidance given supports the implementation of ISO17034. Other approaches can also be used as long as the requirements of ISO17034 are fulfilled.
Brief guidance on the need for commutability assessment (6.11) is given in this document, but no technical details are provided. A brief introduction for the characterization of qualitative properties (9.6 to 9.8) is provided, together with brief guidance on sampling such materials for homogeneity tests (7.4.1.2). However, statistical methods for the assessment of the homogeneity and stability of RMs for qualitative properties are not covered. This document is also not applicable to multivariate quantities, such as spectral data.
NOTE ISO 33406 gives more information on the production of RMs with one or more qualitative property values.
