3.2.3

Crosslinked Verification (Crosslinking Proof Test)

When finished wire is tested in accordance with 4.6.5.1, the insulation shall not crack or fail

dielectrically. When finished cable is tested in accordance with 4.6.5.2, the jacket shall not

crack or, if shielded and jacketed, fail dielectrically.

3.2.4

Dielectric Withstand

One hundred percent of finished cable shall pass the dielectric withstand test with an

application time of 15 to 30 seconds, without breakdown, using the voltage specified in the

applicable SCD.

3.2.5

Identification and Color Striping Durability

There shall be no discontinuity of identification mark or color stripe after subjecting the mark

or stripe to the number of cycles and the test load specified in the applicable SCD.

Additionally, stripes shall not flake or crack when the finished wire, or component wire prior

to cabling, is wound back on itself.

3.2.6

Identification of Product

When specified by the procuring activity, finished wire or cable shall be identified by a

marking applied to the outer surface. The identification shall consist of the appropriate mark

as specified by the contract or the applicable SCD. The mark color shall be in accordance

with MIL-STD-104, Class 1, and shall be contrasting to that of the marking surface.

Identification shall be applied with the vertical axis of the printed characters parallel to the

longitudinal axis of the wire or cable when the nominal diameter of the marking surface is

0.050 inch (1.3 mm) or smaller. The vertical axis of the printed characters may be either

perpendicular or parallel to the longitudinal axis of the wire or cable when the nominal

diameter of the marking surface exceeds 0.050 inch (1.3 mm).

3.2.7

Insulation or Jacket Concentricity

The concentricity of the total wire insulation, or cable jacket, shall be 70 percent, minimum.

3.2.8

Insulation or Jacket Elongation

When finished wire or cable is tested in accordance with 4.6.9, the elongation of the total wire

insulation (for dual-walled insulations, both layers pulled together as a unit), or the cable

jacket, shall be 50 percent, minimum.

3.2.9

Insulation or Jacket Flaws

One hundred percent of finished wire, unshielded and unjacketed cable, and shielded and

jacketed cable shall pass the impulse dielectric test or the spark test specified in 4.6.10 using

the voltage specified in the applicable SCD. Testing shall be performed during the final

winding of the wire or cable on shipment spools or reels.
