The test method is used to determine the relative wear preventive properties and load bearing capacity of lubricating fluids in sliding contact under the prescribed test conditions. Few standard ASTM tests are mentioned below.
- ASTM D2266 Standard Test Method for War Preventative Characteristics of Lubricating Grease (Four-Ball Method)
- ASTM D4172 Standard Test Method for Wear Preventative Characteristics of Lubricity Fluids (Four-Ball Method)
- ASTM D5183 Standard Test Method for Determination of the Coefficient of Friction of Lubricants
