This standard is applicable to service brakes of various passenger cars and two brakes (front/rear) are required to be tested. 1 Test Item 1.1 Brake efficiency test. 1.2 Brake heat fade-and-recovery test. 1.3 Pipeline failure and assistor failure tests. 1.4 Wear test. 2 Test Apparatus and Instrument 2.1 Apparatus 2.1.1 Inertia type double-wheel braking bench (or single-wheel bench); its acceleration performance shall meet the cycle time specified in fade test. 2.1.2 Bench pressure-feed system; it shall meet the requirements for pressure under various braking conditions and remain stable. 2.1.3 Bench cooling device; it shall keep the wind speed at tested brake be 11m/s. 2.2 Instrument and the precision requirement Instrument for indicating and recording braking moment, brake temperature, braking distance, braking time, braking pipeline liquid pressure and rotational speed of bench axle; with allowable tolerance equal to or less than ±2% of instrument full range. 2.3 The allowable tolerance of control parameters such as braking pipeline liquid pressure and brake temperature is ±5%. The allowable tolerance of rotational speed of bench axle is ±2%. Rotational inertia shall include the inertia of bench rotating part, and its allowable tolerance is ±5%.
