标准摘要
[中文适用范围]： 本部分IEC 63522用于测试机电式基本继电器（机电继电器、干簧继电器、干簧触点、干簧开关及其技术组合），并评估其在运输、存储和所有操作使用预期条件下的性能。 本文档定义了适用于低负载应用（例如CC 0、CC 1）的机电式基本继电器接触故障率测试的标准测试方法，以及在指定条件下的低负载故障率和故障率等级。 [外文原描述]： IEC 63522-48:2024 is used for 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 for contact failure rate test of electromechanical elementary relays applied to low-load applications (e.g., CC 0, CC 1) and failure rates and failure rate levels at low loads under specified conditions. The content of the corrigendum 1 (2025-04) has been included in this copy.
