Standard Test Method for Determining the Coefficient of Friction of Synchronizer Lubricated by Mechanical Transmission Fluids (MTF) Using a High-Frequency, Linear-Oscillation (SRV) Test Machine

Importancia y uso:

5.1 This test method can be used to quickly determine the lubricating ability of fully-formulated lubricants used as mechanical transmission fluids (MTF) to display a frictional behavior against materials used in synchronizers of mechanical gears in automotive vehicles. This test method has found to be complementary to bench tests (for example, Test Method D5579 and CEC L-66-99) by using the present test conditions. This test method is a material and application oriented approach based on inputs from field experiences for characterizing the frictional behavior (coefficient of friction (cof)) using random, discrete, and constant parameter combinations as seen in field experiences. Users of this test method should determine whether results correlate with field performance or other applications prior to commercialization.
