ASTM D4055-04(2019) PDF

Scope: 1.1 This test method covers the determination of pentane insolubles for particles exceeding 0.8 µm in new and used lubricating oils. NOTE 1—Pentane insolubles with particle sizes less than 0.8 µm may be studied with appropriate size membrane filters. Particle sizes above or below 0.8 µm can be studied. The precision of this test method has been determined only at 0.8 µm. 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. For specific warning statements, see 7.1, 8.2.1, and Annex A1. 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.
