New Determination of the Temperature of Gold and Silver Points on the Thermodynamic Temperature Scale

The freezing points of gold and silver are determined by a constant volume nitrogen gas-thermometer with a gas bulb made of silica glass. The temperature of the gold point which is adopted as 1063.0°C on the International Temperature Scale is determined as {aligned} TAu{=}1336.84{±}0.05 {aligned} on the Kelvin Scale and {aligned} tAu{=}1063.69{±}0.05 {aligned} on the Celsius Scale. The temperature of the silver point which is 960.8°C on the International Temperature Scale is {aligned} TAg{=}1234.43{±}0.05 tAg{=}961.28{±}0.05 {aligned} on the Kelvin and Celsius Scales respectively.
