本国际标准规定了尺寸，以确保牵引车和牵引车之间的互换性 耦合式半挂车，两者共同构成铰接式车辆。它规定了一定的互换性 尺寸，包括鹅颈管轮廓的尺寸，以及与角度值相关的操作尺寸。这个 规范允许同一辆半挂车与两轴或三轴拖拉机一起使用。 附录A给出了设计用于牵引高立方体半挂车的拖拉机的接口技术规范，包括: 外部高度为2.9 m的ISO容器。 本国际标准涵盖了商业货物运输中使用的尽可能多的铰接式车辆 不同种类然而，它可能不适用于特殊的组合类型，如低床或自卸车。 本国际标准未规定最大总质量和外形尺寸的限制，这些限制如下: 通常由立法规定。

This International Standard specifies dimensions to ensure interchangeability between a tractor vehicle and a coupled semi-trailer, the two together constituting an articulated vehicle. It specifies certain interchangeability dimensions, including those of the gooseneck contour, as well as operating dimensions related to angle values. The specifications permit the same semi-trailer to be used with either two- or three-axle tractors. Annex A gives interface technical specifications for tractors designed for towing high-cube semi-trailers, including ISO containers having an external height of 2,9 m. This International Standard covers articulated vehicles used in commercial cargo transport of the greatest possible variety. However, it may not be applicable to special combination types such as low-bed or tipper vehicles. This International Standard does not provide limitations of maximum gross mass and overall dimensions, which are generally laid down by legislative requirements.
