新的！IEC 60445:2017作为IEC 60445:2017 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60445:2017适用于电气设备端子的识别和标记，例如电阻器、保险丝、继电器、接触器、变压器、旋转机器，以及在适用的情况下，此类设备的组合（例如组件），也适用于某些指定导体端子的识别。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，以避免歧义并确保安全操作。这些导体颜色或字母数字符号旨在应用于电缆或芯、母线、电气设备和装置。？本基本安全出版物主要供技术委员会根据IEC中规定的原则编制标准时使用？导游？104和ISO/IEC？导游？51.根据IEC指南104，它具有基本安全出版物的地位。本第六版取消并取代了IEC第五版？60445，2010年出版。？与上一版相比，此版本包括以下重大技术变更:a)引言文本已根据IEC移入范围？导游？104;b)用于识别直流系统线路导体的颜色代码；c)用于识别功能性接地导体的颜色代码；d)用直流线路导线的颜色代码更新表A.1；e)将载有非强制性要求的说明转换为规范性文本；f)术语是否符合IEC？60050-195.

NEW!IEC 60445:2017 is available as IEC 60445:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60445:2017 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.This sixth edition cancels and replaces the fifth edition of IEC？60445, published in 2010.？This edition includes the following significant technical changes with respect to the previous edition:
a) the text of the introduction has been moved into the scope in accordance with IEC？Guide？104;
b) colour codes for the identification of line conductors of DC systems;
c) colour code for the identification of functional earthing conductor;
d) update of Table A.1with colour codes for DC line conductors;
e) conversion of notes containing non-mandatory requirements to normative text;
f) the terminology is aligned with IEC？60050-195.
