Historical Standard: ASTM D4172-94(1999) Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method)
SUPERSEDED (see Active link, below)
ASTM D4172
1. Scope
1.1 This test method covers a procedure for making a preliminary evaluation of the anti-wear properties of fluid lubricants in sliding contact by means of the Four-Ball Wear Test Machine. Evaluation of lubricating grease using the same machine is detailed in Test Method D2266.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the test the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents, therefore each system must be used independently of the other. Combining values of the two systems may result in nonconformance with the specification.
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.
