Results of investigations of and an improvement in GET 161–2001, the State Primary Standard of hardness of metals based on the Shore D scale, are presented. The process of improvement in the standard was carried out at the All-Russia Research Institute of Physicotechnical and Radio Measurements (VNIIFTRI)from 2016 to 2018 for the purpose of assuring the uniformity of measurements of hardness based on the Leeb scales. New hardness components, such as stands for reproduction of the hardness numbers in the Leeb scales, were developed and constructed. GET 161–2019, the State Primary Standard of the hardness of metals based on the Shore D scale and the Leeb scales, was approved. The metrological characteristics of GET 161–2019 were investigated and the budget of measurement uncertainty in reproduction of hardness numbers based on the Leeb scales was compiled.
