环境试验第2-18部分:试验试验R和指南:水

[中文适用范围]： 本部分IEC 60068适用于在运输、储存或使用过程中可能受到水滴、冲击水、浸泡或高压水冲击影响的产品。水测试的主要目的是验证外壳、盖子和密封件在标准化的水滴场或水中浸泡后以及必要时在浸泡期间保持组件和设备良好工作状态的能力。 这些测试不是腐蚀测试，不能被视为或用作腐蚀测试。 其他标准中确立的水测试不旨在模拟自然降雨，其引用的强度太高，无法用于该目的。因此，除了高强度严酷度外，测试R还包括基于自然条件但不考虑通常与自然雨相关的高风速的人工降雨测试。 提供了关于测试适用性和应选择的严酷度的指导。 [外文原描述]： IEC 60068-2-18:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60068-2-18:2017 provides methods of test applicable to products which, during transportation, storage or in service, can be subjected to falling water drops, impacting water, immersion or high pressure water impact. The primary purpose of water tests is to verify the ability of enclosures, covers and seals to maintain components and equipment in good working order after and, when necessary, under a standardized drop field or immersion in water. These tests are not corrosion tests and cannot be considered and used as such. Established water tests in other standards are not intended to simulate natural rainfall and their quoted intensities are too high to be adopted for that purpose. Therefore, in addition to the high-intensity severities, test R includes an artificial rain test based upon natural conditions but not taking into account high wind speeds generally associated with natural rain. Guidance is given on the applicability of the tests and the severities to be selected. This third edition cancels and replaces the second edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. addition of the new test method Rb 3.
