Road vehicles — Braking threshold pressures for heavy commercial vehicle combinations with fully pneumatic braking systems — Test with roller brake tester ISO 20918:2007

General information

Current stage: 90.93 Standard confirmed Jun 17, 2021

Originator: ISO

Owner: ISO/TC 22/SC 33 Vehicle dynamics and chassis components

Type: International Standard

ICS: 43.040.40 Braking systems

Scope

ISO 20918:2007 describes a method to evaluate the braking threshold of heavy commercial vehicle combinations with pneumatic braking systems, by means of a 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.
