Road vehicles -- Braking threshold pressures for heavy commercial vehicle combinations with fully pneumatic braking systems -- Test with roller brake tester
ISO 20918:2007 describes procedures for workshops and garages and provides
- a recommended pressure range of the system threshold pressure for motor vehicles and trailers, and
- a recommended practice for determining the system threshold pressure.
ISO 20918:2007 covers neither high-pressure compatibility, including the control of the coefficient of friction between lining/pad and drum/disc, nor dynamic influences. ISO 20918:2007 is not for use at Type Approval.
