New Guide for Measurement of Coefficient of Friction Differences between Oils and Related Fluids in Laboratory Tribotests

1. Scope

This guide lists the details of ASTM and selected other oil tests that produce information about the friction component of an oil in a particular tribosystem. This guide compares these tests in those areas to serve as a basis of selecting test methods that are most appropriate for a given application. Users of this guide must decide on which test or tests best simulates their tribosystem of interest. A table comparing available tests can be used as a selection aid.

Keywords

Coefficient of friction, lubricant testing, oil friction, lubricity, friction testing, oil testing, four-ball testing, SRV testing, HFRR testing

Rationale

There are many ASTM and other testing standards that produce a coefficient of friction for lubricating oils. Most involve different tribosystems and lubrication conditions (boundary, hydrodynamic, etc.). Some are wear tests. Comparing different oils for their effect on system friction requires one to select specific tests to use from the many that are available. This guide lists commonly used tests that are candidates for consideration for use when trying to assess friction contribution differences between oils. This guide has been previously balloted in G02.50 (22-01) and all negatives and comments for previous ballots addressed in this revision. This revision clarifies the apparatus and procedure section. They are advisory since this is a guide and not a test method.
