Significance and Use
5.1 Evaluations by both test methods differentiate between fluids having low, medium, and high levels of extreme-pressure properties. The user should establish any correlation between results by either method and service performance.
Note 3: Relative ratings by both test methods on the reference fluids covered in Repeatability Reproducibility s = 0.0624 S = 0.140 r = 0.179 (TL)D R = 0.402 (TL)D Repeatability Reproducibility s = 0.0624 S = 0.137 r = 0.179 (TL)E R = 0.391 (TL)E
s = 0.0624
S = 0.140
r = 0.179 (TL)D
R = 0.402 (TL)D
s = 0.0624
S = 0.137
r = 0.179 (TL)E
R = 0.391 (TL)E
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 calibration curve.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.
