SAE No. 2 Friction Test Machine μPVT Test
The SAE No. 2 Friction Test Machine is used to evaluate the friction characteristics of automatic transmission plate clutches with automotive transmission fluids. It can also be used to conduct durability tests on wet friction systems.
The specific purpose of this document is to define a μPVT Test for the evaluation of the variation of wet friction system performance as a function of speed, temperature, and pressure. This procedure is intended as a standard for both suppliers and end users.
The only variables selected by the supplier or user of the friction system are: a. Friction Material; b. Fluid; and c. Reaction Plates.
These three variables must be clearly identified when reporting the results of this test.
