The State primary standard of the unit of specific heat capacity of solids GET 60-2019

Abstract

The paper describes the creation of the new State standard of thermal capacity of solids. The main point of the project is the design of the high accuracy adiabatic calorimeter КА-С4. The construction and the modes of operation of installation are presented. The sources of uncertainty and the resulting values of accuracy are analyzed. Also the paper contains the information about the measures for the transmitting of the unit to the devices of lower accuracy.
