Standard Test Method for Oil Separation from Lubricating Grease During Storage

Significance and Use

5.1 When a lubricating grease separates oil, the remaining composition increases in consistency. This can affect the ability of the product to function as designed.

5.2 It has been found that the results of this test correlate directly with the oil separation that occurs in 35-lb pails of grease during storage.

5.3 This test method is not intended to predict oil separation tendencies of the grease under dynamic conditions.


1.1 This test method covers the determination of the tendency of a lubricating grease to separate oil during storage in both normally filled and partially filled containers.

1.2 This test method is not suitable for greases softer than NLGI No. 1 grade.

1.3 The values stated in SI units are to be regarded as standard, except for the dimensions in Fig. 2 and Fig. 5, where inch-pound units are standard.

1.4 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. For a specific hazard statement, see 7.1.
