商用道路车辆——刚性牵引杆的牵引杆联轴节和钩眼第1部分:普通货物中轴挂车的强度试验
This International Standard specifies the test conditions and strength requirements to be met by drawbar couplings
(see ISO 3584) and the corresponding drawbar eyes (see ISO 1102 and ISO 8755) for rigid drawbars, which are
provided for use with centre-axle trailers with a technical maximum mass C exceeding 3,5 t (tonnes).
