Core marking
Colour code according to DIN 47100 (twisted pairs) with colour repetition
Core marking and the colours of the insulating cover are executed in accordance with DIN 47002 and DIN IEC 60304 (in conformity with Harmonization Document HD 402 S2).
Configuration of the cores or core pairs is effected in accordance with the tables shown below.
To improve identification and also for safety reasons, the brighter colour (the first colour) is defined as the basic colour and the darker colour (second colour) as the top colour.
The colour combination consists of 10 basic colours. As from Core No. 11, marking is accomplished by means of one or two coloured rings, with a ring width of 2 to 10 mm.
Ring spacing is approx. 7 mm.
Counting procedure: Counting starts at the outermost layer and proceeds consecutively and in the same direction inward through all the layers.
