ASTM D2265-15e1

5.1 The dropping point is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control. The results are to be considered to have only limited significance with respect to service performance because dropping point is a static test.

5.2 Cooperative testing3 indicates that, in general, dropping points by Test Method D2265 and Test Method D566 are in agreement up to 260 °C. In cases where results differ, there is no known significance. However, agreement between the manufacturer and purchaser as to test method used is advisable.

1.1 This test method covers the determination of the dropping point of lubricating grease.

1.2  This test method uses mercury thermometers. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
