# ASTM D3233

Standard Test Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Pin and Vee Block Methods)

[Back to all techniques](/analytical-techniques/)

## 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 fluids covered in Table X2.1 and Table X2.2 are in good general agreement with four-ball weld-point relative ratings obtained on these same fluids, covered in Test Method D2783.

## Scope

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 Appendix X1 regarding coefficient of friction, load gauge conversions, and load gauge 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.
