ASTM D2511-93(2019)
(Test Method)Standard Test Method for Thermal Shock Sensitivity of Solid Film Lubricants
Standard Test Method for Thermal Shock Sensitivity of Solid Film Lubricants
SIGNIFICANCE AND USE
5.1 Solid lubricant coatings are applied to surfaces that are exposed to heat and cold to such a degree that in many cases liquid lubricants are not practical. Adherence under these conditions is mandatory to preserve the bearing surfaces during sliding motion.
SCOPE
1.1 This test method covers the measurement of the resistance of dry solid film lubricants to deterioration when subjected to temperature extremes.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
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.
