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.

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
