https://doi.org/10.32446/0368-1025it.2022-7-58-62
Abstract
The article presents the results of measurements of the temperature coefficient of linear expansion and the proportion of heat capacity of tungsten, copper, silver, molybdenum, beryllium, sapphire, carbon-carbon composite material of the TERMAR DF KO brand. Studies of all materials were carried out on the state primary standards of D. I. Mendeleyev Institute for Metrology (VNIIM) in recent years. The authors analyzed the stability of the reproduction of properties by materials. The authors analyzed the stability of the properties of materials and established the feasibility of using these materials for the manufacture of means for reproducing and transmitting thermophysical units.
