Standard Test Methods for
Measurement of Extreme Pressure Properties of Fluid
Lubricants (Falex Pin and Vee Block Methods)1

This standard is issued under the fixed designation D 3233; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. 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
NOTE 1—Additional information can be found in Appendix X1 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.

2. Referenced Documents

2.1 ASTM Standards:
B 16/B 16M Specification for Free-Cutting Brass, Rod, Bar
and Shapes for Use in Screw Machines2
D 2670 Test Method for Measuring Wear Properties of
Fluid Lubricants (Falex Pen and Vee Block Method)3
D 2783 Test Method for Measurement of Extreme-Pressure
