适用范围：This International Standard specifies the various elements and dimensions of a tractor vehicle and a coupled semi-trailer which together constitute an articulated vehicle, in order to ensure interchangeability.It specifies certain interchangeability dimensions of the gooseneck contour and operating dimensions relating to some angle values.The requirements of this International Standard permit use of the same semi-trailer with two-axle or three-axle tractors.NOTE — The dimensions of the 50 mm and 90 mm fifth-wheel coupling pins are specified in ISO 337111 and ISO 4086'2' respectively. Mounting zones for pneumatic braking couplings are specified in ISO 1728131.The articulated vehicles are intended for commercial transport of cargo of the greatest possible variety: this International Standard does not necessarily cover special combination types (e.g. high-cube vehicles, low-bed vehicles, tipper vehicles).Limitations of maximum gross m?ss and overall dimensions are generally laid down by legislative requirements.
