GB/T 35472.5-2017 "Wet Automatic Transmission Friction Element Test Methods, Part 5: Durability Test Methods" standard specifies in detail the procedures for the durability test of wet automatic transmission friction elements using SZBL type friction tester. The standard covers the test equipment, typical test conditions and parameters, test procedures, data collection and result reports. The test is mainly at 3600r/min or 6000r/min Rotation speed, through the Power increment test to evaluate the performance change of wet friction elements under different cycles to ensure its durability and Reliability. The standard provides a systematic test method and evaluation basis for the long-term performance evaluation of friction elements.
