ASTM D8022-20

5.1 It is known that contamination by water can affect the structural stability of some greases in service. The test procedure specified in this method is widely used to determine the wet structural stability of greases in service. Many grease specifications require this procedure as a wet structural stability test. No accurate correlation is established between the test results and wet structural stability of grease in actual service.

1.1 This test method covers a procedure for determining the roll stability of lubricating grease in the presence of water (wet roll stability) by using a roll stability test apparatus.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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.

1.4 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.
