+AMD1:2026 CSV 人机界面、标识和识别基本安全原则 - 设备端子、导体终端和导体的识别

[中文适用范围]： IEC 60445:2021+AMD1:2026 CSV适用于电阻器、熔断器、继电器、接触器、变压器、旋转电机等电气设备的端子识别和标记，适用于这些设备（如组件）的组合，也适用于某些指定导体端子的识别。本标准还提供了一些通用规则，用于使用特定颜色或数字字母符号来识别导体，以避免歧义并确保安全运行。这些导体颜色或数字字母符号应应用于电缆或芯线、母线、电气设备和安装中。本基本安全出版物主要用于技术委员会制定标准时使用，符合IEC指南104和ISO/IEC指南51中规定的原则。根据IEC指南104，本标准具有基本安全出版物的地位。IEC 60445:2021取消并替代了2017年发布的第六版。本版构成技术修订。与前一版相比，本版包括以下重大技术变更：a) 定义与IEC 60050-195:2021和IEC 60050-826保持一致；b) 对于某些指定导体用于识别的颜色，现在作为强制性要求而非建议；c) 新增了关于设备多电源输入保护端子标记的子条款。 [外文原描述]： IEC 60445:2021+AMD1:2026 CSV 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.
