The article presents the results of studies to improve the National primary standard machine for hardness of metals on the shore D scale GET 161-2001, which were performed in FSUE “VNIIFTRI” from 2016 to 2018 in accordance with the technical task of Rosstandart.The improvement was carried out in order to ensure the uniformity of hardness measurements on the Leeb scales. The created new parts of the primary standard machine, which are settings for reproducing hardness numbers on the Leeb scales, are considered. Metrological characteristics of the upgraded and adopted National primary standard machine (GET 161-2019) were investigated, the budget of measurement uncertainty was calculated for reproducing hardness numbers on the Leeb scales.

Methods and instruments the characteristics of porosity and permeability of solids and materials are described, which are part of the improved GET 210-2014. The metrological characteristics of the GET 210-2014 are compared and after its improvement the GET 210-2019. Certified reference materials of approved types based on micro-, meso- and macroporous solids are considered. The results of international comparisons, confirmed measuring and calibration capabilities, as well as a comparison of the metrological characteristics of the GET 210-2019 with the standards of foreign countries are presented.
