    Significance and Use

    This test method differentiates between bonded solid lubricants with respect to their wear life and load-carrying capacity. If the test conditions are changed, wear life may change and relative ratings of the bonded solid film lubricants may be different.

    1. Scope

    1.1 This test method (see Note 1) covers the determination of the endurance (wear) life and load-carrying capacity of dry solid film lubricants in sliding steel-on-steel applications.

    Note 1—Reference may be made to Coordinating Research Council, Inc. (CRC) Report No. 419, Development of Research Technique for Measuring Wear Life of Bonded Solid Lubricant Coatings for Airframes, Using the Falex Tester. See also Military Specification MIL-L-8937 (ASG), Jan. 22, 1963, and Methods 3807 and 3812 of Federal Test Method 791a.

    1.2 The values stated in SI units are to be regarded as the standard except where equipment is supplied using inch-pound units and would then be regarded as standard. The metric equivalents of inch-pound units given in such cases in the body of the standard may be approximate.

    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.
