4.5.13.2 Procedure. The specimens selected for checking cable as a whole shall be attached to a

2.38 inch (60.45 mm) mandrel. The specimens removed from the cable for checking the insulation apart

from the cable shall consist of the insulated conductors with all the other coverings over the insulation

removed. One of each differently color insulated conductor shall be attached to the proper size mandrel.

The number 16 AWG insulated conductor shall be attached to a .094 inch (2.39 mm) mandrel and the

number 20 AWG insulated conductor shall be attached to a .062 inch (1.57mm) mandrel. The specimens

shall be suspended vertically with lower ends weighted sufficiently to keep specimens taut and to prevent

bending them without handling. The mandrel and specimens shall be placed for at least 20 hours in the

cold chamber at a temperature of minus 40 � 2C. While at this temperature, the specimens shall be bent

for five close turns around the mandrel at the rate of approximately 15 turns per minute. After the test has

been completed, the jacket on the specimen of cable shall be examined through a magnifying glass of at

least three-diameter magnification and then removed. The conductor insulation on all specimens shall be

examined for cracks with magnifying glass as specified in 3.15.

4.5.14 Marking of cable. Samples of the cable shall be examined as specified in 3.16.

4.5.15 Insulating and jacketing compounds. The insulating and jacketing compounds shall be

examined and tested as specified in MIL-DTL-3432.

4.5.16 Conductors and shield strands. The conductors and shield strands prior to fabrication of

cable shall be examined and tested as specified in A-A-59551.

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 that may be helpful, but is not

mandatory.)

6.1 Intended use. The cable covered by this specification is most commonly used as a power or

audio frequency interconnecting cable between communication equipments at potentials up to 300 volts

rms.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a. Title, number, and date of this specification.

b. The specific issue of individual documents referenced (see 2.1).

c. Packaging requirements (see 5.1).

d. Classification of cable required (see 1.1).

e. Length of cable required.
