Abstract

ISO 14794:2003 specifies open-loop test methods for determining the effect of braking on the course holding and directional behaviour of heavy vehicles or heavy vehicle combinations when braking is accomplished using the service-brake system, or the retarder or engine brake only. It is applicable to heavy vehicles -- i.e. commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 -- covered by Categories M3, N2, N3, O3 and O4 of UNECE (United Nations Economic Commission for Europe) and EC vehicle regulations. These categories pertain to trucks and trailers with a maximum mass above 3,5 t and to buses and articulated buses with a maximum mass above 5 t.
