ISO 20120:2025 Scope

This document specifies a test method for determining the coefficient of friction and its evolution in mechanical transmission fluids tribologically interacting with materials used in synchronizers in manual transmission (MT) gears under high-frequency linear oscillation motion using the linear-oscillation (SRV) test machine. A flat areal contact geometry is applied.
