An internally consistent Mueller bridge and a reliable value of the ice point resistance are required for the accurate determination of temperatures with a platinum resistance thermometer. The decade steps of Mueller bridge, serial No. 1603629 were intercompared and the resistance of a standard resistor was measured. The triple point resistance of platinum resistance thermometer, serial No. 1586182 was measured in a commercial triple point of water cell. From these measurements, corrections for each dial reading of the bridge were tabulated, and the ice point resistance of the platinum resistance thermometer was computed
