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.

Note 1: All dimensions are in millimeters (inches).

Note 2: Tolerances are ±0.51 mm (0.02 in.) for 2 place decimals, unless otherwise specified.

Note 3: Tolerances are ±0.127 mm (0.005 in.) for 3 place decimals, unless otherwise specified.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 7.1.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
