ASTM D 6184 : 2017

1.1This test method covers the determination of the tendency of lubricating grease to separate oil at an elevated temperature. This test method shall be conducted at 100 °C for 30 h unless other conditions are required by the grease specification.

1.2This test method can be used on any grease with a worked penetration (Test Methods D217) greater than 220 mm/10 (NLGI Consistency Number 3 or softer). However, no precision data exists for greases with a penetration greater than 340 mm/10 (softer than NLGI Consistency Number 1).

1.3The values stated in SI units are to be regarded as standard. The term 60 mesh is used to describe the wire mesh used. This unit was described in the withdrawn E437 standard and there is no exact metric equivalent.

1.4This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use.

1.5This 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.
