标准摘要
[中文适用范围]： 本文件建立了推荐的做法，以验证中型卡车、重型卡车以及公共汽车和拖车应用中使用的金属部件和组件的可接受的腐蚀性能。该文件的重点是加速测试和结果评估的方法。提供了适合测试车辆上不同位置的组件的各种测试程序。该程序包含循环条件，包括腐蚀性化学品、干燥、湿度和磨料暴露。这些程序旨在有效评估表 1 中列出的各种腐蚀机制。可以调整测试持续时间以达到任何所需的暴露水平。还考虑了关节旋转、机械应力和极端温度等恶化条件。本文件不涉及腐蚀化学或防腐蚀方法。有关这些领域的信息，请参阅 SAE J447 或类似标准。 [外文原描述]： This document establishes recommended practices to validate acceptable corrosion performance of metallic components and assemblies used in medium truck, heavy truck, and bus and trailer applications. The focus of the document is methods of accelerated testing and evaluation of results. A variety of test procedures are provided that are appropriate for testing components at various locations on the vehicle. The procedures incorporate cyclic conditions including corrosive chemicals, drying, humidity, and abrasive exposure. These procedures are intended to be effective in evaluating a variety of corrosion mechanisms as listed in Table 1 . Test duration may be adjusted to achieve any desired level of exposure. Aggravating conditions such as joint rotation, mechanical stress, and temperature extremes are also considered.This document does not address the chemistry of corrosion or methods of corrosion prevention. For information in these areas, refer to SAE J447 or similar standard.Cross Reference:
