MIL-DTL-3432J
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order
(see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel
need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are
maintained by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or
within the military service's system commands. Packaging data retrieval is available from the managing Military
Department's or Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible
packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature which may be helpful, but is not mandatory).
6.1 Intended use. The cables covered by this specification are intended for use by the Armed Services in
extensive electrical and electronic applications. The cables may be used to transmit power, synch pulses, data
transmission voltages, broadband, audio, or control power. The shielded cables are suitable for radio-frequency use
in limited applications. A tough and flexible jacket is essential because the cables will be subjected to extreme
mechanical abuse and extreme humidity and temperature conditions. Cables designated for light, medium, and
heavy-duty are for use as indicated in 6.1.1 through 6.1.3.
6.1.1 Light-duty (L) cables. Light-duty cables are intended for use in test equipment in short lengths, or for
interconnection of major components. They are intended to withstand severe flexing and frequent manipulation.
Light-duty cables should not be used where they will be stepped on, run over by vehicles, beaten, or subjected to
severe impacts. Light-duty cables are suitable for lightweight portable tools or small motor and generator leads
where flexibility rather than long life is essential.
6.1.2 Medium-duty (M) cables. Medium-duty cables are intended to withstand the same usage as heavy duty
cables except they should not be used where they will be run over by vehicles or subjected to severe impacts. They
are intended to be a substitute for all uses of heavy-duty cables when the reduction in weight would be advantageous
to the equipment they are used in. Medium-duty cables are suitable for small portable tools, sound equipment, radio
receivers, and motor leads, which do not require the heavier, sturdier, heavy-duty cables.
6.1.3 Heavy-duty (H) cables. Heavy-duty cables are intended for use where they will be subjected to extreme
service impacts or will be run over by heavy vehicles, such as trucks, tanks, or the like. They are designed to
withstand severe flexing and mechanical abuse over long periods of time without deterioration. Heavy-duty cables
are suitable for portable tools, extension lamps, charging cables, and control cables.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of the specification.
c. Complete type designation (see 1.2.1).
d. Lengths required.
e. Packaging requirements (see 5.1).
6.3 Definitions.
6.3.1 Insulated conductor. A conductor consists of a stranded wire, with insulating covering, suitable for carrying
an electric current.
6.3.2 Equipment ground wire. An insulated conductor (green) intended for grounding non-current-carrying metal
parts of equipment.
6.3.3 Wire. A single metallic conductor of stranded construction designed to carry current in an electrical circuit.
