MIL-DTL-49055F
6.4 Definitions.
Conductor. A conductor is a single conductive path in a conductive pattern.
Conductor diameter. The conductor diameter is the diameter of the total circular cross section of the
conductor, including all metallic conductor coatings.
Current-carrying capacity. The current-carrying capacity is the maximum current that can be
continuously carried through a conductor under specified conditions.
Delamination. Delamination is a separation between any of the layers of the base laminate or
between the laminate and the mated conductors, or both.
Dielectric strength. The dielectric strength is the maximum voltage that a dielectric material can
withstand, under specified conditions, without rupturing; usually expressed as volts/unit thickness.
Flat cable. Flat cable is any cable with two or more parallel conductors in the same plane enclosed
by an insulating material.
Insulation resistance. Insulation resistance is the electrical resistance of the insulating material,
determined under specified conditions, between any pair of conductors.
Laminate. A laminate is a product made by bonding together two or more layers of material with
pressure, heat, or adhesive.
Margin. The margin is the distance between the edge of a flat cable and the centerline of the
nearest conductor.
Solderability. Solderability is the property of a metal to be wetted by solder.
Unit of product. The unit of product is each reel, spool, or coil of cable.
Wetting. Wetting is the free flow and spreading of solder on conductive paths and terminals to form
an adherent bond.
6.5 Fungus resistance. Guideline 4 of MIL-HDBK-454 includes a listing of fungus-inert materials
(group I) and fungus nutrient materials (group II) and provides guidelines on the use of preferred and
acceptable materials.
