New Test Method for ASTM Standard Test Method for Traction Curve Measurement on a Ball on Disc Tribometer

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.


Traction curve, friction, ball on disc, tribology, traction fluids


• Traction data is typically used by lubricant or additive manufacturers who are trying to optimise formulations (usually to reduce energy losses) in non-conforming lubricated contacts.
• The use of traction data is, however, not limited to this application and has been used to qualify the performance of skin creams, food formulations, clutch fluids, and solid lubricants amongst other.
• This set of test conditions is not the only way to conduct traction curve measurements, however, it is a standard method. that would be used consistently.

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