3.2.10

Removability of Insulation

For AWG 10 and smaller finished wires, 0.5 inch (13 mm) of insulation shall be readily

removable using conventional, hand-operated, wire strippers with properly-sized blades for the

construction. The insulation slug shall not bunch, nor shall any conductor strands break

during the removal process.

3.2.11

Shield Construction and Coverage

The optical coverage of braided or spiral shields shall be 85 percent, minimum. Braided

shields shall have an angle of 18 to 35 degrees relative to the axis of the cable.

3.2.12

Workmanship

Workmanship of finished wire and cable shall be uniform and free of external, or internal,

physical or cosmetic irregularities.

3.3

QUALIFICATION SPECIFIC REQUIREMENTS

These characteristics, noted by the code "Q" in Table 3, are a function of the combination of

materials and processes used to produce a given wire or cable construction. Following

qualification, adherence to material specific and process specific requirements assures that the

product will continue to meet the initial qualification specific requirements. Qualification

specific requirements shall be as follows, when tested on the following constructions:

Wire: 55PC0211-20 and 55PCF0211-20, as applicable

Cable: 55PC1221-22 and 55PCF1221-22, as applicable

Conductor plating and/or shield plating substitutions may be allowed provided the wire or

cable construction is otherwise the same as specified.

3.3.1

Blocking

When finished wire or cable is tested in accordance with 4.6.1, adjacent turns and layers of the

wire or cable shall not block. Blocking shall be defined as a transfer of material between

adjacent surfaces when they are separated.

3.3.2

Flammability

When finished wire or cable is tested in accordance with 4.6.7, the burn length shall not

exceed 3 inches (76 mm), the afterburn time shall not exceed 3 seconds, and there shall be no

flaming of the facial tissue.

3.3.3

Insulation or Jacket Tensile Strength

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

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

jacket, shall be 5000 lbf/inch
