This test method is intended primarily to differentiate between liquid thin film lubricants which exhibit the properties of Newtonian flow with respect to their endurance (wear) life and load carrying capacity when they are used in a manner similar to the bonded dry solid film lubricants. (See Test Method D 2625
for definition of dry solid film lubricants.) The test conditions for thin film lubricants are very critical and must be maintained to ensure reliability of the data when used to compare different lubricants. Liquid thin film lubricants which exhibit the properties of non-Newtonian flow can also be tested if the procedure for preparing the pin and vee blocks is modified to account for their different behavior.
1.1 This test method covers the determination of the endurance (wear) life and load carrying capacity of thin film fluid lubricants that are intended to operate after a single application and after excess material has drained from the contact area of sliding metal to metal surfaces, and which operates in what functionally is a drain and dry mode with no additional lubricant being applied.
1.2 The values stated in SI units are to be regarded as the standard except where equipment is supplied using inch-pound units which would then be regarded as the standard. The values 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 and health practices and determine the applicability of regulatory limitations prior to use.
