本SAE推荐规程旨在使用惯性测功机程序对带空气制动器的公路商用车辆上使用的制动鼓进行鉴定试验。 本文件由两个不同的试验组成:A部分，耐久性和速度维持试验，B部分，热检查阻力顺序试验。每个测试都可以被视为对制动鼓的独立评估，它测试不同的财产。

This SAE Recommended Practice is intended for qualification testing for brake drums used on highway commercial vehicles with air brakes using an inertia-dynamometer procedure. This document consists of two distinct tests: Part A, durability and speed maintenance test, and Part B, heat check drag sequence test. Each test can be considered to be an independent evaluation of the brake drum which tests different properties.
