SPECIFICATION 80, ISSUE 1 Page 7
3.5.2 Color
Color shall be in accordance with MIL-STD-104, Class 1. White is preferred for both
insulation and jacket. Color code designators, and colored stripes and bands, if used, shall
be in accordance with MIL-STD-681.
3.5.3 Conductor and Shield Continuity
When finished cable is tested in accordance with MIL-C-27500, there shall be no loss of
continuity in the conductors or shield.
3.5.4 Crosslinking Proof Test
When finished wire and cable is tested in accordance with 4.6.4, there shall be no cracking of
the insulation or jacket and no dielectric breakdown.
3.5.5 Flammability
3.5.5.1 Procedure 1
When qualification samples are tested in accordance with 4.6.7.1, the burn length shall not
exceed 3 inches (76 mm) and the afterburn time shall not exceed 3 seconds.
3.5.5.2 Procedure 2
When AWG 22 and 20 wire specimens are tested in accordance with 4.6.7.2, the burn length
shall not exceed 3 inches (76 mm) and the afterburn time shall not exceed 3 seconds.
3.5.6 Identification of Product
When specified, the finished wire and cable shall be identified by a marking applied to the
outer surface. The identification shall consist of the appropriate mark as specified by contract
or the applicable specification sheet. The mark shall be in a contrasting color to that of the
finished wire or cable. Identification shall be applied with the vertical axis of the characters
parallel to the longitudinal axis of the wire when the nominal diameter of the wire is 0.050
inch (1.27 mm) or smaller. The vertical axis of the characters may be either perpendicular or
parallel to the longitudinal axis of the wire when the nominal diameter of the wire exceeds
0.050 inch (1.27 mm). Wires with diameters of 0.035 inch (0.89 mm) and smaller shall not be
marked.
3.5.7 Immersion
When qualification samples are tested in accordance with 4.6.8, the diameter change shall be
no more than 5 percent, and there shall be no cracking of the insulation or jacket and no
dielectric breakdown.
3.5.8 Insulation Flaws
One hundred percent of finished wire shall pass the impulse dielectric test or the spark test of
MIL-W-22759 using the voltage specified in the applicable specification sheet. The test shall
be performed during the final winding of the wire on shipment spools or reels.
