MIL-DTL-3432J
3.2.5.2 Stripe tracers. The tracer shall be in accordance with MIL-STD-686. All materials for stripping shall be
nonconductive.
3.2.5.3 Coding by marking. Where prototype models or short runs of cables are specified for procurement (less
than 10,000 feet) and the individual conductors of the cables have an outside diameter of .065 inch (1.65 mm) or
larger, the contractor shall code the conductors by marking or coloring in accordance with MIL-STD-686.
3.2.6 Grouping and cabling. When the cables are grouped (see 1.2.1.5.2 and 1.2.1.5.5), the conductors within the
group shall be twisted together. All the conductors and groups of conductors shall be cabled together in an
arrangement that shall form an essentially round construction (except for parallel conductors). Where there are
mixtures of different conductor sizes and element constructions (shielded singles, shielded pairs), the larger diameter
conductors and shielded wires shall be toward the center.
3.2.6.1 Length of lay. The lay-up of cable layers shall be unidirectional. For cables employing semi- flexible
conductors and ground wires, if applicable, the length of lay shall be not greater than 20 times the outer diameter of
the layer. For cables employing flexible conductors and ground wires, if applicable, the length of lay shall be not
greater than 16 times the outer diameter of the layer. For cables employing extra-flexible conductors and ground
wires, if applicable, the length of lay shall be not greater than 12 times the outer diameter of the layer. The outer
diameter of the layers is the diameter over the separator or binder, if used (see 3.2.6.4).
