本国际标准规定了测定重型商用车辆横向稳定性的试验方法 ISO 3833中定义的组合，包括卡车中轴拖车组合和铰接式客车。它是 适用于质量超过3.5 t的卡车和拖车，以及质量超过5 t的公共汽车，即车辆 根据92/53/EEC分类N2、N3、O3、O4和M3。 这些试验方法中规定的操纵不能完全代表实际驾驶条件，但有一定的局限性 用于确定重型车辆组合的横向稳定性。

This International Standard specifies test methods to determine the lateral stability of heavy commercial vehicle combinations as defined in ISO 3833, including truck centre-axle trailer combinations and articulated buses. It is applicable to trucks and trailers having a mass exceeding 3,5 t and buses having a mass exceeding 5 t, i.e. vehicle categories N2, N3, O3, O4 and M3 according to 92/53/EEC. The manoeuvres specified in these test methods are not fully representative of real driving conditions, but are useful for determining the lateral stability of a heavy vehicle combination.
