本SAE推荐规程确立了一种测试所有新卡车、客车、车辆和车辆制动系统结构完整性的方法，以及设计用于道路使用和坠落的以下分类的组合车辆:拖车和客车:超过4500 kg（10000磅）GVWRB组合车辆:超过4500 kg（10000磅）GVWRB的牵引车该试验包括两个不同的试验:结构耐久性试验，然后是结构极限强度试验。注:这两项试验源自单独的程序，并在本推荐规程中结合使用。每次测试都可以被认为是对行车制动器结构的独立评估。基于可用的时间、成本限制以及所需的评估和可用的历史数据，这些测试都可以被视为对制动器结构的完整评估。

This SAE Recommended Practice establishes a method of testing the structural integrity of the brake system of all new trucks, buses, and combination vehicles designed for roadway use and falling in the following classifications:aTruck and bus: Over 4500 kg (10000 pounds) GVWRbCombination vehicle: Towing vehicle over 4500 kg (10000 pounds) GVWRThe test consists of two distinct tests: a structural endurance test followed by a structural ultimate strength test.NOTE: These two tests originated from separate procedures, and were combined in this recommended practice. Each test can be considered to be an independent evaluation of the service brake¿¿¿s structure. Based on time available, cost limitations, and the desired evaluation and historical data available, either of these tests could be considered as a complete evaluation of the brake¿¿¿s structure.
