Abstract

IEC 60757:2021 specifies letter codes for designation of colours and provides rules for their combination to designate colour combinations. The letter codes are intended to be applied in the technical documentation of electrical installations, electrical equipment and products, and in markings of electrical equipment and products.
This basic safety publication focusing on safety essential requirements is primarily intended for use by technical committees in the preparation of safety publications in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
It is not intended for use by manufacturers 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 the relevant publications.
This document does not specify any requirements for the encoding of colour properties, nor for their visual representation. Such requirements are under the responsibility of the different technical committees.

IEC 60757:2021 cancels and replaces the first edition published in 1983. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) codes restricted to letter codes;
b) removed old unnecessary notes;
c) added a new subclause on alternating colours of the same item;
d) added Annex A with examples of colours and their corresponding RGB (red, green, blue) encoding.
