It is not intended for use by manufacturer

29、s or certification bodies. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements of this basic safety publication will not apply unless specifically referred to or included in th

30、e relevant publications. In this fifth edition of IEC 60445, the terminology has been aligned with IEC 60050-195.

31、CTORS 1 Scope This International Standard 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 th

32、e 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 inte

33、nded to be applied in cables or cores, busbars, electrical equipment and installations. 2 Normative references The following referenced documents are indispensable for the application of this document.
