IEC 62491:2008 PDF

Scope: This standard provides rules and guidelines for the labelling of cables and cores/conductors used in industrial installations, equipment and products, in order to maintain a clear relation between the technical documentation and the actual equipment and for other purposes. The following methods are described and designated: ~ use of coloured cables and designated cores; ~ additional identification labelling; ~ additional connection labelling; and ~ additional signal labelling. The physical design of the labels, the material to be used for the labels as well as cable manufacturers' product bound marking of cables and cores are not part of this standard.
