The multiplication of national units transfer instruments with established values of metrological traceability in international organisations is one of the most actual development directions for a large number of countries, inasmuch as this direction contributes to the solution of a global problem of measurement results comparability which were received for various objects in different times in different parts of the world as well as indicates the high quality of measuring capabilities of an organisation or a country. The paper contains issues of establishment of metrological traceability of results of physicochemical measurements. The international practice on traceability establishment of reference materials’ certified values is described in the work. The authors also provided a brief overview of internationally accepted fundamental concepts of reference materials metrological traceability demonstration.
