本SAE推荐规程（RP）适用于用于测量摩擦材料和摩擦材料组件挠度（压缩性、蠕变或膨胀和增长）的试验系统的验证过程。这些材料或组件可适用于乘用车、轻型卡车和配备液压或空气制动系统的商用车辆，使用盘式或鼓式制动器。

This SAE Recommended Practice (RP) applies to the validation process for test systems used to measure deflection (compressibility, creep, or swell and growth) of friction materials and friction material assemblies. The materials or assemblies can fit passenger cars, light trucks, and commercial vehicles equipped with hydraulic or air brake systems, using disc or drum brakes.
