ISO 26865:2009适用于UNECE R.E.3中定义的M2、M3、N2、N3、O3和O4类商用车辆，这些车辆配备了空气制动器。 ISO 26865:2009适用于产品开发、产品原型、产品规格或验证以及正在进行的系列生产，如ISO 15484中所定义。 当与其他适用标准或测试程序结合使用时，ISO 26865:2009旨在提供对摩擦材料是否适合在特定应用、市场或车辆平台中使用的完整评估。 ISO 26865:2009不包括在速度、温度、轮胎与路面的附着力、负载和制动系统的操作条件等不同车辆条件下与制动距离或制动力分布相关的性能要求，如联邦法规或法规所示。ISO 26865:2009规定了单端惯性测功机性能程序，旨在将配备空气制动器的商用车辆的各种程序标准化为一个涵盖所有相关性能要求的独特程序。 测试序列包括以下条件的性能评估: 垫料前后性能测试； 垫料后和中温后刹车褪色； 对温度、速度和压力影响的敏感性； 下坡模拟； 制动回收。

ISO 26865:2009 applies to commercial vehicles of the categories M2, M3, N2, N3, O3 and O4, as defined in UNECE R.E.3, which are equipped with air brakes. ISO 26865:2009 applies during product development, product prototypes, product specification or validation, and ongoing series production, as defined in ISO 15484. When used in conjunction with other applicable standards or test procedures, ISO 26865:2009 is intended to provide a complete assessment of a friction material's adequacy for use in a certain application, market or vehicle platform. ISO 26865:2009 does not include performance requirements related to stopping distance or braking force distribution, under different vehicle conditions of speed, temperature, tyre-to-road adhesion, loads and operating conditions of the braking system, as indicated in Federal Codes or Regulations. ISO 26865:2009 specifies a single-ended inertia-dynamometer performance procedure, which is intended to standardize the various procedures for commercial vehicles equipped with air brakes into one unique procedure covering all performance requirements of interest. The test sequence includes performance evaluation for the following conditions:

• performance test before and after bedding;
• brake fade after bedding and after moderate temperature;
• sensitivity to temperature, speed and pressure influence;
• downhill simulation;
• brake recovery.
