examinations of 4.6.
4.5 Visual and dimensional inspection. Strands and completed wire shall be inspected to verify
that the materials and all workmanship comply with this specification.
4.5.1 Construction and lay. Construction and lay shall be determined by physical examination
and measurement of the complete wire.
4.6 Breaking strength and elongation. Breaking strength and elongation shall be made on a
tensile strength machine, preferably of the pendulum types. Breaking strength test shall be made
after stranding, on the completed wire. The free length between grips of the test specimen shall
be not less than 60 inches (1524.00 mm) and the speed shall be not more than 3 inches (76.20
mm) per minute. Care shall be taken to insure that strands in the stranded wire are evenly
gripped during test. (Successfully testing of stranded wire for tensile properties requires an
adequate means of gripping the ends of the test specimen. Various means are available, such as
a long tube or socket into which the wire may be soldered, or in which, after insertion, the wires
may be swaged or pressed without serious distortion. Ordinary jaws or clamping devices are
usually not suitable). At the conclusion of the test, the wire shall meet the requirements for
5. PACKAGING

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.
