摘要：
The results of studies designed to improve the State Primary Standard of the unit of specific heat capacity (GET 60-74) carried out from 2017 to 2019 are described. A complex of high-precision measurement instruments that form the new State Primary Standard of the heat capacity of solids (GET 60-2019) at the head of which is the KA-S4 high-precision calorimeter was created. A set of standard measures of specific heat capacity was created to reproduce and transmit the unit from GET 60-2019 to lower-echelon measurement instruments. The measurement chain for transmission of the unit of specific heat capacity from GET 60-2019 to lower-echelon measurement instruments was developed. The expanded uncertainty of measurements performed on the basic KA-S4 adiabatic calorimeter of the standard complex in the working temperature range of GET 60-2019 does not exceed 0.27–0.36% with conformance factor k = 2.
