标准摘要
[中文适用范围]： 本推荐实践(RP)建立了用于评估推进电池组防水密封性的非破坏性在线生产测试方法。它旨在使用SAE J3277中定义的选择等效通道(EC)方法实现与IEC 60529标准IPX7级别相当的结果。本RP为系统设置、工具设计、验证和泄漏测试程序提供指导。它承认某些电池组设计的局限性，并推荐适当的空气或示踪气体密封技术。 [外文原描述]： This recommended practice (RP) establishes nondestructive in-line production test methods for evaluating the water leak tightness of propulsion battery packs. It aims to achieve results equivalent to the IEC 60529 standard’s IPX7 level using the Selected Equivalent Channel (EC) method defined in SAE J3277. This RP provides guidance for system setup, tooling design, validation, and leak test procedures. It acknowledges the limitations of certain battery pack designs and recommends appropriate air or tracer gas leak tightness technologies. Specifically, this RP covers nondestructive end-of-line leak testing for: Battery pack assembly: Ensuring protection against water ingress into the battery pack. Coolant system: Verifying the integrity of the coolant system and preventing coolant leaks into the battery pack.
