Scope

This document specifies the general requirements, determination of Dc and V values,
dynamic tests, static tests and strength requirements for drawbar couplings and
matching drawbar eyes.
This document applies to the strength test of the drawbar eye and the matching drawbar
coupling used in the following vehicle types.
-- Rigid drawbar trailers, with a maximum design total mass exceeding 3500 kg
and with a vertical static load acting on the towing vehicle exceeding 10% of
the maximum design total mass of the trailer and/or greater than 1000 kg but
not exceeding 2000 kg, and the combinations composed of the trailers;
-- Vehicle transport trailers with a maximum design total mass exceeding 3500 kg
and the combinations composed of the trailers.
This document is not applicable to the strength test of drawbar couplings and matching
drawbar eyes as specified in ISO 12357-1.
