MIL-DTL-10392F
3.4.2 Conductor strand tensile strength and elongation. The tensile strength and elongation of the
coated strands, removed from the insulated conductors prior to cabling, shall be as follows:
Tensile strength: 45,000 psi, max.
Elongation in 10 inches: 13 percent, maximum.
3. 4.3 Conductor strand resistance. Each conductor strand shall have a direct current resistance of
1,310 Ω maximum per 1000 feet at a temperature at or corrected to 20º C. If the resistance value is lower
or equal to that specified, when the measurement is made at a temperature greater than 20º C, no
correction factor will be needed (see 4.5.5).
3.5 Inner separator. An inner separator shall be applied over each conductor. The separator shall
consist of a suitable number of ends of yarn conforming to MIL-C-572, type AR, CTA, or VCR, closely
wound to cover the conductor. If however, the insulating compound applied in accordance with 3.7 is free
stripping, the separator may be omitted.
3.6 Insulation. A styrene butadiene rubber (SBR) insulating compound, type IS or type ISL, shall be
applied over the conductor or inner separator, when present, to a minimum thickness of 0.007 inch
(.18 mm). Insulated conductors having a nominal area of 404 circular mils (24 AWG) shall have a
maximum diameter of 0.059 inch (1.50 mm). Insulated conductors having a nominal area of 1620 circular
mils (18 AWG) shall have a maximum diameter of 0.097 inch (2.46 mm).
3.7 Color coding.
3.7.1 Cords having all 24 AWG conductors. Cords having all 24 AWG conductors shall use the
following colors, in the sequence listed:
1-White
6-Blue
2-Black
7-Brown
3-Red
8-Yellow
4-Green
9-Gray
5-Orange
10-Purple
3.8 Cords WM-69B/U, WM-70B/U, and WM-111A/U. Cords WM-69B/U, WM-70B/U and WM-111A/U
shall be color coded as specified on table II.
