Evaporation Loss

ASTM D972
IP 183

Evaporation Loss of Lubricating Greases and Oils.
This test method covers the determination of the loss in mass by evaporation of lubricating greases and oils for applications where evaporation loss is a factor. Evaporation loss data can be obtained at any temperature in the range from 100 to 150°C (210 to 300°F).
