Commercial road vehicles. Coupling equipment between vehicles in multiple vehicle combinations. Strength requirements Ingestion-build-105964 Who is BS 7121-1 -1 Scope This International Standard 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. NOTE For these vehicle combinations, the formulae in this International Standard override the formulae in References [6], [7], [8], and
