E. Aslanyan, A. Doynikov, V. Pivovarov

Abstract

Design specifics and study results are provided for the new National Shore D scale hardness standard. At the metrological study of the standard the calculations of uncertainty in measurements with two methods are considered: in accordance with the international guide on expression of uncertainty in measurement and in accordance with the principles based on the scales of order properties. <br /> According to the metrological study, the standard ensures the reproduction and dissemination of the scale in the actually used range of HSD numbers of 20 to 102 with an HSD uncertainty of no more than 0.5.
