The subrange inconsistency (SRI) of a large ensemble of long-stem standard platinum resistance thermometers (SPRTs), representative of worldwide production, has been investigated for all pairs of ITS-90 overlapping subranges between 83.8058 K and 933

Heat loss is one of the key parameters that cause temperature errors during the calibration of thermometers in metal-freezing-point cells and thus increases the measurement uncertainty. At temperatures above the freezing point of tin, thermal radiati
