Standard Test Method for Wear Preventive Characteristics of Lubricating Grease (Four-Ball Method)
|Publication Date:||15 September 1991|
|ICS Code (Lubricants, industrial oils and related products):||75.100|
This test method covers the determination of the wear preventive characteristics of greases in sliding steel-on-steel applications. It is not intended to predict wear characteristics with metal combinations other than steel-on-steel or to evaluate the extreme pressure characteristics of the grease.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety problems, 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.
