新的！IEC 60068-2-18:20 17作为IEC 60068-2-18:20 17 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60068-2-18:20 17提供了适用于在运输、储存或使用过程中可能受到下落水滴、冲击水、浸没或高压水冲击的产品的测试方法。水测试的主要目的是验证外壳、盖子和密封件在标准化跌落场或浸入水中后以及必要时在水中保持组件和设备处于良好工作状态的能力。这些试验不是腐蚀试验，不能作为腐蚀试验考虑和使用。其他标准中已建立的水测试并非旨在模拟自然降雨，其引用的强度太高，无法用于此目的。因此，除了高强度严重性之外，测试R包括基于自然条件的人工降雨测试，但不考虑通常与自然雨相关的高风速。对测试的适用性和要选择的严重性给出了指导。这第三版取消并取代了2000年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a.增加新的试验方法Rb 3。

NEW!IEC 60068-2-18:2017 is available as IEC 60068-2-18:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.
