The effect of covariance on uncertainty when constructing the ITS-90 temperature scale

The effect of covariance between the resistances of a calibrated standard platinum resistance thermometer at the fixed points on the uncertainty when constructing the ITS-90 temperature scale in the 0–660°C range is considered. The proposed method of calculating the uncertainty complies with the int...

Beschreibung
Zusammenfassung:The effect of covariance between the resistances of a calibrated standard platinum resistance thermometer at the fixed points on the uncertainty when constructing the ITS-90 temperature scale in the 0–660°C range is considered. The proposed method of calculating the uncertainty complies with the international recommendations.
