电气继电器 测试和测量 第13部分：由于硫影响引起的腐蚀性气氛

[中文适用范围]： 本文件用于测试机电式基本继电器（机电继电器、簧片继电器、簧片触点、簧片开关及其技术组合），并评估其在运输、储存和所有操作使用预期条件下的性能。 本文件定义了一种标准测试方法，用于模拟硫酸性大气对继电器的影响。测试条件模拟了一种人为情况，并允许对被测设备（DUT）在已知和现有开关解决方案方面的可用性进行性能比较。 该测试是一种静态测试，不实际运行DUT，以模拟腐蚀的最坏情况，因为腐蚀会随着时间的推移而增加。腐蚀层可能会造成触点粘连、增加电阻或在继电器中产生其他不良影响。这些方面可能会受到测试期间DUT动作的影响，这些动作可能会破坏腐蚀层或掩盖相关的长期效应。 除了污染大气外，DUT在盐雾大气中的使用和/或储存适宜性可以按照IEC 63522-44的描述进行评估。 [外文原描述]： IEC 63522-13:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method to simulate impacts of sulfuric atmospheres to relays. The test conditions simulate an artificial situation and allow a performance comparison for usability of the devices under test (DUT) with regard to known and existing switching solutions. The test is a static test without actual operation of the DUT to simulate a worst-case scenario for corrosion, since corrosion increases over time. The corrosion layer can potentially create contact sticking, increase resistance or other undesired effects in the relay. Those aspects can be affected by DUT actuations during the test, which can destroy the corrosion layers or hide relevant long-term effects. In addition to polluted atmospheres, the suitability of the DUT for use and/or storage in corrosive atmospheres can be assessed in a salt-laden atmosphere as described in IEC 63522-44.
