FTM 321 - Oil Separation from Lubricating Grease
We perform grease quality testing by FTM 321 to determine the tendency of the oil in lubricating grease to separate at high temperatures. The grease sample is heated in a wire-gauze cone for 30 hours at a constant temperature, and the percentage by weight of the oil drained through the cone is measured as the oil separation.
This test method has been replaced since its release by ASTM D6184.
