MIL-DTL-3849C
4.6.3.2.2 Cold bend (insulated conductors) (see 3.7.2). The specimens selected for checking the
insulation apart from the cord shall have the jacket or braid removed, and each insulated tinsel wire
conductor shall be tested and examined in accordance with the procedures specified in 4.6.3.2.1.
4.6.3.3 Sea-water resistance (see 3.7.3). After exposure to a salt water solution the specimens shall
meet the requirements of 3.7.3. The following details shall apply:
a. One specimen from each sample unit, at least 3 feet (0.91 m) in length, shall be weighed and
the weight recorded.
b. The specimen shall then be immersed in a salt-water solution composed of distilled water and a
3.5 percent solution of sodium chloride for a period of 10 days at room temperature.
c. After removal from the solution, each specimen shall be wiped clean and weighed again to
determine weight change before and after immersion.
d. The specimens shall also be examined for evidence of chemical reaction or other deleterious
effects.
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 Controls 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 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 that may be helpful, but is not
mandatory.)
6.1 Intended use. The cords covered by this specification are intended for low-voltage, audio-
frequency use, where extreme flexibility is required. These cords are primarily for use with telephones,
switchboards, microphones, and associated communications equipments. The cables covered by this
specification are militarily unique because of requirements to survive salt water submersion, sea-water
resistance (weight change of the cord), and bend at -40 °C. Commercial electronic cable components are
not designed to withstand these extreme conditions or sudden environmental changes, and would
experience catastrophic failure.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of this specification.
b. Title, number, and date of the applicable specification sheet and the complete PIN (see 3.1).
c. First article contract requirements, when required.
d. Certificate of compliance covering materials, when required.
e. Length and quantity of finished cords to be delivered.
