人机界面、标记和标识的基本原则和安全原则.设备终端、导线终端和导线的标识

[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）的端子和某些指定导体的端接部位的识别与标记，同时也适用于这些设备组合（例如组件）的识别。此外，本文件还提供了使用特定颜色或字母数字表示法识别导体的通用规则，旨在避免歧义并确保安全运行。这些导体颜色和字母数字表示法旨在应用于芯线、母线、电气设备以及电缆或安装系统中。本基础安全出版物侧重于安全 Essential 要求，主要供技术委员会根据 IEC 指南 104 和 ISO/IEC 指南 51 规定的原则编制标准时使用。它不打算供制造商或认证机构使用。技术委员会的责任之一是，在适用的情况下，在编制出版物时使用基础安全出版物。除非相关出版物特别引用或包含这些要求，否则本基础安全出版物的要求不适用。 [外文原描述]： IEC 60445:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
