标准摘要
[中文适用范围]： 本部分IEC 60068提供了一种测试方法，用于确定组件、设备或其构成材料（以下简称样品）在意外接触流体时不受不可接受影响的能力。本部分IEC 60068所列流体代表操作应用中常见的流体。样品不需要暴露于所有或任何流体。该列表也不完整；未列出但适合测试的流体应包含在相关规范中。附件A提供了关于测试流体、样品和严重程度选择的指南。这些测试不适用于证明组件或设备在连续接触流体（如浸入式燃油泵）中的适用性，也不用于证明抗电解腐蚀的免疫力。 [外文原描述]： 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. 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.
