BS ISO 9816:2018规定了开环试验方法，以确定车辆在转弯时对因松开油门踏板而导致的动力突然下降的反应。它适用于ISO 3833中定义的乘用车。本试验方法中规定的开环操纵不代表实际驾驶条件，但有助于获得在严格控制的试验条件下，由特定类型的控制输入产生的车辆断电行为的测量值。交叉引用:ISO 15037-1:2018ISO 8855ISO 2416:1992（R04）ISO 1176:1990ISO 3833ISO 4138购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 9816:2018 specifies open-loop test methods to determine the reactions of a vehicle in a turn to a sudden drop in motive power resulting from release of the accelerator pedal. It applies to passenger cars as defined in ISO 3833.The open-loop manoeuvre specified in this test method is not representative of real driving conditions, but is useful to obtain measures of a vehicle's power-off behaviour resulting from specific types of control inputs under closely controlled test conditions.Cross References:ISO 15037-1:2018ISO 8855ISO 2416:1992 (R04)ISO 1176:1990ISO 3833ISO 4138All current amendments available at time of purchase are included with the purchase of this document.
