标准摘要
[中文适用范围]： 本国际标准适用于电阻器、熔断器、继电器、接触器、变压器、旋转电机等电气设备端子的识别和标记，以及在适用的情况下，适用于此类设备的组合（例如组件），也适用于识别某些指定导体的端接。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线、母线、电气设备和装置中。 [外文原描述]： IEC 60445:2010 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 fifth edition is a merged version of IEC 60445 and IEC 60446, and cancels and replaces the fourth edition of IEC 60445, published in 2006, and the fourth edition of IEC 60446, published in 2007. This edition includes the following significant technical changes with respect to the previous edition: - addition of new definitions in Clause 3; - revision of some clauses to use words from reference IEC standards. These revisions did not change any technical requirements but to clarify the wording; - addition of Annex B (informative) "List of notes concerning certain countries". It has the status of a horizontal standard in accordance with IEC Guide 104 .
