摘要

The state and prospects for further improvement in State Primary Standard of the unit of temperature in the range from 0 to 3000°C GET 34–2007 are considered. The basic problems that have to be solved in the course of improving GET 34–2007 include providing the ability to reproduce the kelvin in accordance with its new definition (scheduled to come into force in 2019) at a temperature above 961.78°C, increasing the precision of reproducing the kelvin 1.5–2.0-fold, and expanding the range of reproduction of the unit of temperature to 3200°C. Ways of improving GET 34–2007 to implement the 1990 International Temperature Scale (ITS-90) in the range 273.15–1235 K are demonstrated.
