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)
ASTM D2878 ESTIMATING APPARENT VAPOR PRESSURES AND MOLECULAR WEIGHTS OF LUBRICATING OILS
This test method covers a calculation procedure for converting data obtained by Test Method D972 to apparent vapor pressures and molecular weights. It has been demonstrated to be applicable to petroleum-based and synthetic ester lubricating oils, at temperatures of 395 to 535K (250 to 500°F). However, its applicability to lubricating greases has not been established.
