New Guide for Standard Guide for Measurement of Coefficient of Friction Differences Between oils and Related Fluids in Laboratory Tribotests
1. Scope
The promotion of knowledge, stimulation of research, formulation of definitions and terminology, and development of methods of testing and data analysis, relating to wear, friction, and erosion of materials and structures.
The areas of interest of the Committee shall be the response of solids to mechanical interactions that occur due to relative motion between a solid material and a contacting substance or substances. This includes surface-to-surface or particle-to-surface sliding or rubbing, flow of fluids or slurries, impingement by liquid jets, drops, or solid particles, and cavitation of contacting liquids. These phenomena sometimes coexist, interact, or overlap with somewhat related phenomena, such as corrosion or lubrication. The work of the Committee will be coordinated with other ASTM Committees and other organizations having mutual interests, including ASTM Committees G01 on Corrosion of Metals and D02 on Petroleum Products and Lubricants, ASME, STLE, ASM, SAE, and others.
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.
