Enjoy definition
3.1 Cable identification mark
Use words, letters, symbols, colors and other marks to mark the manufacturer, product trademark, model, specification, performance, etc. of the wire and cable. 3.2 Insulated wire core identification mark
Use Arabic numerals and colors (single color or combination of colors) to distinguish different insulated wire cores of multi-core cables or indicate the functions of the insulated wire cores. 3.3 Standard color
is the color specified for the identification mark and is represented by a color palette. 3.4 Color sequence
When using color identification for the insulated cores of multi-core cables (more than two cores), the preferred colors (including combined colors) and their sequence rules are specified.
