1.1 These test methods cover two procedures for making a preliminary evaluation of the load-carrying properties of fluid lubricants by means of the Falex Pin and Vee Block Test Machine.

Note 1—Additional information can be found in regarding coefficient of friction, load gage conversions, and load gage cablibration curve.

1.2 The values stated in SI units are to be regarded as standard. Because the equipment used in these test methods is available only in inch-pound units, the SI units are omitted when referring to the equipment and the test specimens.

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.
