New Guide for Standard Guide for Measurement of Coefficient of Friction Differences Between oils and Related Fluids in Laboratory Tribotests

1. Scope

This guide compares the details of ASTM and selected other oil tests that produce information on the friction component of an oil in a particular tribosystem. Users of this guide must decide on which test or tests best simulates their tribosystem of interest.

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.). 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 and some tests that should be considered for use when trying to assess friction contribution differences between oils.

The title and scope are in draft form and are under development within this ASTM Committee.
