-
For multi wire, twisted or not, threads are inserted between the
external sheath and the conductors.
The thread and printing must resist the maximum operating temperature of
the wires.

C. Identification by Printed Tapes
This identification includes a series of digits and letters printed on a
tape.
Printing will be done along the whole length of tape :
-
at minimum pitch of 300 mm (11.8110 in.) plus or minus 50 mm (1.9685 in.) when printing is visible through the external sheath.
-
at maximum pitch of 75 mm (2.9527 in.) plus or minus 25 mm (0.9842 in.)
in the other cases.
Printing must be dark-colored.
R For single cable, tapes are inserted during the manufacturing phase
R between the core and the insulation sheath or between the external sheath and the insulating sheath.
R For multicore cable, twisted or not, tapes are inserted between the
R external sheath and the conductors.
The tape and printing must resist the maximum operating temperature of wires.

D. Application of Identification
(1) United States (US) wire types :
R (a) Single-core cables : Printing on external sheath for gauge 6 to 26. Colored thread for gauge 0000 and 4.
R (b) Twisted multi-core cables : - Printing of composition element reference (e.g. : AKA-FF-G-20). - Printing of assembly reference on blue-colored wire (e.g. : QD-FF-G-20).
R (c) Shielded single-core cables : - Printing of composition element reference on the element. - Printing of the assembly reference on the external sheath.
R (d) Shielded multi-core cables : - Colored threads under the sheath. - Printing of composition element reference on the blue-colored wire (e.g. : AKA-FA-G-20). - Printed tape positioned under the external sheath. - Printing of assembly reference on the external sheath. - Printing of the assembly reference on the blue-colored wire (e.g. : TJB-EF-R-24). - Printing of the element reference on each element (e.g. : AKB-FF-R-20).
R (2) Metric (M) cable types :
R (a) Single-core cables : Printing on the external sheath.
R (b) Twisted multi-core cables : Printing of composition element reference and its color on each element (e.g. : CF20X-FA-A). Element color as per para. 6.
R (c) Shielded single-core cables : - Printing of element reference on the element. Mandatory printing of the assembly reference on external sheath. - For laser printed cable, marking only on the external sheath. Marking on the element is optional.
