ASTM D128 - Lubricating Grease Analysis


We perform lubricating grease quality testing by ASTM D128, which gives several methods for determining and estimating the makeup of lubricating greases. ASTM D128 includes the soap, oil, water, free alkalinity, free fatty acid, fat, glycerin, and insoluble content of grease. These tests can be used to identify and estimate some of the constituents of lubricating greases. Grease composition does not always have a direct effect on service performance.
