3.7 Cable identification. The method of identification shall be compatible with the cable construction
as indicated by type designation (see 1.2.1). Identification shall be at intervals of 1 to 3 feet and may be
by marking of the outer jacket or tape placed beneath the shield or jacket. All materials used for
identification shall conform to the environmental requirements of the particular construction. The
identification shall be clear and legible and shall include the following where practicable:
MIL-DTL-55021/(add specification sheet number and revision), manufacturer's name or
CAGE code (CAGEC), type designation, and year of manufacture.
Example: MIL-C-55021/2C XXXXX (CAGEC) E24C904-903-902SF 2000
Finished unjacketed and unshielded cable shall be identified with the printed marking of a contrasting
color applied to the surface of any of the wires in a multiconductor cable (see example above). The size
of the printed characters shall be compatible with the basic wire size. No other printed marking shall be
applied to the basic wire.
3.8 Workmanship. Cable shall be uniform in shape and free of kinks, splints, cuts, cracks, abrasions,
and foreign material. The basic wire(s) in the cable shall be free from any imperfections that can affect
performance.
