Internal and external influences in the realization of ITS-90

Popis výsledku v původním jazyce

In the realization of international temperature scale (ITS-90) is important to keep the requirements of Supplementary documents realized by BIPM. In addition of that, every national institute has their own requirements for proper realization of ITS-90. The aim of this work is to provide inputs for better understanding of the processes inside and outside of the metal fixed point?s cells. There are four main contributors for the overall calibration uncertainty of standard platinum resistance thermometer (SPRT) according to the ITS-90. - Fixed points - SPRT - Instrumentation -External influences This article will deal with influences of SPRT and ambient environment to the results. In first part, the subranges inconsistencies will be investigated on several types of SPRT calibrated in the laboratory of CMI. Interpolation uncertainty will be compared with the results of least squares method for these SPRT. Second part will deal with influences of furnaces used for the realisation of the fix
