ASTM D566 - Dropping Point of Lubricating Grease


We perform grease testing by ASTM D566 to determine the dropping point of lubricating grease. The dropping point is the temperature at which grease passes from semisolid to liquid under test conditions. The grease sample is heated in a cup with a hole in the bottom. The temperature at which grease falls from the hole in the cup is the dropping point of the grease sample. 

We also perform drop point testing by ASTM D2265 and ASTM D3954. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
