1）常用制动与缓解性能试验Performance test for common braking and releasing
司机控制器手柄自零位分别置常用级1～7级制动位，待制动缸压力稳定后，司机制动控制器手柄移回0位。记录各级制动时制动缸最高压力、常用7级制动时制动缸从零升至最高压力90%的时间及制动缸由最高压力缓解到40kPa的时间。
Place the driver’s controller handle from zero position to one-staged to seven-staged braking positions. After the pressure in the braking cylinder is stabilized, place the handle of driver’s braking controller back to zero position. Record the maximum pressure in the braking cylinder during the various-staged braking, the time of pressure increasing from zero to 90% of the maximum pressure during the common seven-staged braking, and the time of pressure releasing from maximum pressure to 40kPa in the braking cylinder.
2）紧急制动与缓解性能试验Performance test for emergency braking and releasing
司机控制器手柄自零位置紧急制动位，待制动缸压力稳定后，司机控制器手柄移回零位。记录制动缸最高压力、制动缸从零升至最高压力95%的时间及制动缸由最高压力缓解到40kPa的时间。
Place the driver’s controller handle from zero position to emergency braking position. After the pressure in the braking cylinder is stabilized, place the handle of driver’s braking controller back to zero position. Record the maximum pressure in the braking cylinder, the time of pressure increasing from zero to 95% of the maximum pressure in the braking cylinder, and the time of pressure releasing from maximum pressure to 40kPa in the braking cylinder.
3）阶段制动和阶段缓解试验Test for graduated braking and releasing
司机控制器手柄自零位依次置常用1级～7级制动位、紧急制动位，每级制动缸压力稳定后，再进行下一级别制动；阶段缓解试验应待制动缸压力稳定后再依次阶段缓解。记录阶段制动和阶段缓解过程中制动缸压力。
Place the driver’s controller handle from zero position to one-staged to seven-staged braking positions, and emergency braking position, successively. After the pressure in the braking cylinder at each stage is stabilized, conduct the braking at the following stage. The test for graduated releasing should be conducted successively after the pressure in the braking cylinder is stabilized. Record the pressures in the braking cylinder during the graduated braking and releasing process.
