Standard Test Method for Measuring Wear Properties of Fluid Lubricants (Falex Pin and Vee Block Method)
SIGNIFICANCE AND USE
5.1 This test method may be used to determine wear obtained with fluid lubricants under the prescribed test conditions. The user of this test method should determine to his or her own satisfaction whether results of this test procedure correlate with field performance or other bench test machines. If the test conditions are changed, wear values may change and relative ratings of fluids may be different.
SCOPE
1.1 This test method covers a procedure for making a preliminary evaluation of the wear properties of fluid lubricants by means of the Falex Pin and Vee Block Lubricant Test Machine.
Note 1: Certain fluid lubricants may require different test parameters depending upon their performance characteristics.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.

reference.

3.1.4 wear teeth, n—a measurement of wear, which in this test, is based on the number of ratchet wheel teeth advanced during
the test while maintaining load.
3.1.4.1 Discussion—
The number of teeth is directly related to the total wear (inches).
4. Summary of Test Method
4.1 The test consists of running a rotating steel journal against two stationary steel V-blocks immersed in the lubricant sample.
Load is applied to the V-blocks and maintained by a ratchet mechanism. Wear is determined and recorded as the number of teeth
of the ratchet mechanism advanced to maintain load constant during the prescribed testing time.
5. Significance and Use
5.1 This test method may be used to determine wear obtained with fluid lubricants under the prescribed test conditions. The user
of this test method should determine to his or her own satisfaction whether results of this test procedure correlate with field
performance or other bench test machines. If the test conditions are changed, wear values may change and relative ratings of fluids
may be different.
