标准摘要
[中文适用范围]： 本国际标准适用于UNECE R.E.3定义的M2、M3、N2、N3、O3和O4类商用车，且配备气制动系统。本国际标准适用于产品定义和ISO 15484中定义的产品开发、产品原型、产品规格或验证以及持续批量生产。当与其他适用的标准或测试程序结合使用时，本国际标准旨在提供对摩擦材料在特定应用、市场或车辆平台中适用性的全面评估。适用的标准和测试程序包括ISO、JIS/JASO（日本工业标准/日本汽车标准组织）、SAE（汽车工程师学会）、联邦法规或条例以及其他项目或公司特定的测试计划。本国际标准不包括与停车距离或制动力量分布相关的性能要求，这些要求涉及不同的车辆条件，如速度、温度、轮胎与路面的附着力、载荷和制动系统的操作条件，如联邦法规或条例所示。本国际标准规定了一种单端惯性测功机性能程序，旨在将配备气制动的商用车的各种程序标准化为一种独特的程序，涵盖所有感兴趣的性能要求。测试序列包括以下条件的性能评估：制动磨合前和磨合后的性能测试；磨合后和中等温度后的制动衰退；对温度、速度和压力影响的敏感性；下坡模拟；制动恢复。 [外文原描述]： 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.
