The temperature at which a drop of fluid falls from the orifice of the test apparatus under the conditions of ASTM D 2265. The dropping point is not the melting point of lubricating grease. Dropping point is used in many grease specifications. However, this test has very limited relevance to service performance. Dropping point should not be used to determine the upper operating temperature of a grease. However, certain bearing life tests can show how well lubricating grease performs under applied loads at high temperatures under actual operating conditions.
