标准摘要
[中文适用范围]： 本文件适用于电气设备（如电阻器、保险丝、继电器、接触器、变压器、旋转电机等）端子的识别和标记，并在适用的情况下适用于此类设备的组合（如组件），还适用于某些指定导体的端子的识别。它还提供了使用某些颜色或字母数字符号来识别导体的一般规则，旨在避免歧义并确保安全操作。这些导体颜色和字母数字符号适用于芯线、母线、电气设备以及电缆或装置中的导体。本基本安全出版物主要关注安全基本要求，主要用于技术委员会根据IEC指南104和ISO/IEC指南51的原则制定标准时使用。不适用于制造商或认证机构使用。 [外文原描述]： IEC 60445:2021 applies to the identification and marking of terminals of electrical equipment such as resistors, fuses, relays, contactors, transformers, rotating machines and, wherever applicable, to combinations of such equipment (e.g. assemblies), and also applies to the identification of terminations of certain designated conductors. It also provides general rules for the use of certain colours or alphanumeric notations to identify conductors with the aim of avoiding ambiguity and ensuring safe operation. These conductor colours or alphanumeric notations are intended to be applied in cables or cores, busbars, electrical equipment and installations. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It has the status of a basic safety publication in accordance with IEC Guide 104. IEC 60445:2021 cancels and replaces the sixth edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the definitions have been aligned with IEC 60050-195:2021 and IEC 60050-826; b) the provisions for colour to be used for identification of certain designated conductors are made requirements and not only recommendations; c) introduction of a new subclause on marking of protective terminals for multiple power supply inputs on equipment.
