IEC 60068-2-74:1999+A1:2018给出了一种测试方法，该方法提供了一个标准程序来确定部件、设备或其组成材料承受与流体意外接触而不会受到不可接受的影响的能力。列出的流体代表了在操作应用中通常遇到的流体。标本不应该暴露于所有的，甚至任何一个。该列表也不是完整的；未列出且适合测试的液体应包含在相关质量标准中。附录A给出了关于试验液、试样和严重程度的选择的指导。这些试验并非旨在证明部件或设备在与流体（例如浸没式燃料泵）连续接触时的适用性。它们也不是证明抗电解腐蚀的测试。根据IEC指南104，它具有水平标准的地位。该合并版本由第一版（1999年）及其修正案1（2018年）组成。因此，除本出版物外，无需下令修订。

IEC 60068-2-74:1999+A1:2018 gives a method of test which provides a standard procedure to determine the ability of components, equipments or their constituent materials to withstand accidental contact with fluids, without being unacceptably affected. The fluids listed are representative of those commonly encountered in operational applications. It is not intended that a specimen should be exposed to all, or even any of them. Nor is the list intended to be complete; fluids not listed and for which a test is appropriate should be included in the relevant specification. Guidance is given in Annex A on the choice of test fluids, specimens and severities. These tests are not intended to demonstrate the suitability of components or equipments to perform in continuous contact with a fluid, e.g. an immersed fuel pump. Nor are they a test to demonstrate immunity from electrolytic corrosion. It has the status of a horizontal standard in accordance with IEC Guide 104. This consolidated version consists of the first edition (1999) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.
