ISO 12357-2:20 07规定了测试条件和强度要求:
刚性牵引杆的牵引杆联轴器和相应的牵引杆眼,用于刚性牵引杆拖车,其最大设计总质量超过3.5吨且垂直静载荷超过其设计总质量的10%,和/或垂直静载荷大于1 000公斤且不超过2 000公斤;用于车辆运输组合的牵引杆联轴器和相应的牵引杆眼,技术质量超过3.5吨。
ISO 12357-2:2007 lays down test conditions and strength requirements to be met by:
drawbar couplings and corresponding drawbar eyes for rigid drawbars which are provided for use on rigid drawbar trailers with a maximum design total mass exceeding 3,5 tonnes and
a vertical static load exceeding 10 % of their design total mass, and/or
a vertical static load greater than 1 000 kg and up to 2 000 kg;
drawbar couplings and corresponding drawbar eyes for use on vehicle transport combinations, provided for a technical mass exceeding 3,5 tonnes.
