40% to 83% LESS EVAPORATION CHARACTERISTICS

    EVAPORATION LOSS ASTM D-2595

     

    Test method is used to determine the evaporation loss of lubricating greases for applications where evaporation loss is a factor.

    Evaporation loss data can be obtained at any temperature in the range of 210 to 300F (99 to 149C).

    The grease is weighed to the nearest 1 milligram before placing in the evaporation cell.

    The grease is placed in the evaporation cell and the cell is placed in a bath at the desired test temperature. Heated air is flowed through the evaporation cell for 22 hours.

    At the end of 22 hours the sample is allowed to cool to room temperature and re-weighed in order to determine the percent evaporative loss.
