Describes 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.

This International Standard 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.

This International Standard is applicable to heavy vehicles — i.e. commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO3833 — 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 3,5t and to buses and articulated buses with a maximum mass above 5t.
