标准摘要
[中文适用范围]： 本国际标准描述了一种通过滚轮制动测试仪评估带有气动制动系统的重型商用车组合的制动阈值的方法。 本国际标准描述了车间和车库的程序，并提供 - 机动车辆和拖车的系统阈值压力的推荐压力范围，以及 - 确定系统阈值压力的推荐做法。 该国际标准既不涵盖高压兼容性，包括衬里/垫和鼓/盘之间的摩擦系数的控制，也不涵盖动态影响。 本国际标准不适用于型式认证。 [外文原描述]： 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.
英文名称Road vehicles — Braking threshold pressures for heavy commercial vehicle combinations with fully pneumatic braking systems — Test with roller brake tester
