cool, the finished wire specimens shall be freed from tension, removed from the mandrel, and

straightened. The finished wire and cable specimens shall then be subjected to the bend test

(4.6.1) followed by the voltage withstand test (4.6.14).

One inch (25 mm) of insulation shall be removed from each end of a 24-inch (610-mm) speci-

men of finished wire. The central portion of the specimen shall then be bent at least halfway

Proof Test, so that the portion of the insulation between the conductor and mandrel is under

compres-sion while the conductor is under tension. This specimen, so prepared on the mandrel,

shall be conditioned and tested as specified above.

Two inches (51 mm) of the jacket shall be removed from each end of a 15-inch (380-mm)

specimen of finished cable, and the shield, if any, shall be pushed back and formed into a

pigtail at each end of the specimen. One inch (25 mm) of insulation of each of the primary

wires shall then be removed from each end of the specimen. The cable specimen shall then be

Specimens of the wire insulation, or cable jacket, shall be carefully removed and tested for

tion, a jaw speed of 0.2 inch (5 mm) per minute, and a chart speed of 20 inches (508 mm) per

minute. The pounds-force (N) shall be read from the chart 4 inches (102 mm) from where the

trace begins to rise for 0 pounds-force (N).

shall be gradually increased at a uniform rate from zero to the specified voltage in 0.5 minute,

maintained at that voltage for a period of 5 minutes for finished wire specimens and 1 minute

The weight of each lot of finished cable shall be determined in accordance with the procedure

specified for finished wire in MIL-W-22759.

Wire and cable shall be delivered wound on reels or spools in accordance with 5.1.3.

All finished wire lengths wound on one reel or spool shall be spliced into one mechanically

and electrically continuous length.

Finished cable shall be wound with no more than 5 lengths per reel or spool, and in such a

manner that all ends are accessible.

shall be in accordance with Table 5. For finished cable, the minimum acceptable length for

shipment shall be 50 feet (15.2 m).

Reels and spools shall be of a nonreturnable type. Each reel and spool shall have an

appropriate diameter for the respective wire size. In no case shall the barrel of the reel or spool

have a diameter less than 3.5 inches (89 mm). Reels and spools shall be suitably finished to

prevent corrosion under typical storage and handling conditions.

Unless otherwise specified (see 6.1), wire and cable shall be delivered in standard commercial

containers so constructed as to ensure acceptance by common or other carrier for safe trans-
