本国际标准描述了一种开环试验方法，用于确定车辆在直线行驶过程中的反应 在具有分离摩擦系数的表面上进行制动操纵。 它适用于ISO 3833中定义的乘用车。 该方法适用于所有制动力，直到配备了ABS的车辆完全运行，或刚刚达到锁定 对于没有ABS的车辆，车轮在高摩擦表面上的极限。

This International Standard describes an open-loop test method for determining vehicle reactions during a straightline braking manoeuvre on a surface having a split coefficient of friction. It applies to passenger cars as defined in ISO 3833. The method is valid for all braking efforts up to full ABS operation for vehicles so equipped, or just up to the locking limit of the wheels on the high-friction surface for vehicles without ABS.
