ISO 18868:2013

Commercial road vehicles — Coupling equipment between vehicles in multiple vehicle combinations — Strength requirements

ISO 18868:2013 defines different multiple-vehicle combinations (vehicle combinations with more than one coupling point) and the formulae to calculate the requirement of performance for the coupling equipment used in those vehicle combinations. Vehicle categories concerned are N2, N3, O3, and O4.
