Road vehicles — Mechanical coupling between tractors and semi-trailers — Part 1: Interchangeability between tractors and semi-trailers for general cargo
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.
