ISO 11012:2009

Heavy commercial vehicles and buses — Open-loop test methods for the quantification of on-centre handling — Weave test and transition test

Scope

ISO 11012:2009 describes two open-loop test methods for determining on-centre handling characteristics of a vehicle in response to specific types of steering input under closely controlled test conditions:

the weave test, and
the transition test.

ISO 11012:2009 applies to heavy vehicles, i.e. commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, in accordance with ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
