Переопределение кельвина и перспективы совершенствования Государственного первичного эталона единицы температуры в диапазоне от 0 до 3000 °С ГЭТ 34-2007
Abstract
The article examines The state-of-art and prospects for further improvement of the State primary measurement standard of a unit of temperature in the range from 0 to 3000 °С the GET 34-2007. The main tasks that should be addressed in the process of improving that Measurement Standard are as follows: providing the ability to reproduce the kelvin in the range above 961,78oС in accordance with its new definition, which may come into force in 2019; improvement the accuracy of Kelvin's reproduction in 1,5-2 times; extension the range of reproduction of the unit of temperature to 3200oС. The ways of perfection of the GET 34-2007 for realization of the ITC-90 in a range from 273,15 to 1235 K are shown.
