The Investigation of ITS-90 Inconsistency for Standard Platinum Resistance Thermometers in the Sub-range 0C to 419.527C

摘要：

ITS-90 inconsistency is a problem of the temperature scale. Basing on the derived relation by one of the authors, the inconsistency has been checked for eighty-nine SPRTs in the sub-range 0℃ to 419.527℃. The inspection confirmed that the derived criteria coefficient, c, is available to determine the inconsistency of all tested SPRTs used in the range of 0℃ to 419.527℃, that the inconsistency, △t, can be simply equal to 59.83c.
