MIL-DTL-55425E

3.5.4 Dielectric strength cable. The cable shall withstand a potential of 1,000V rms for one minute when tested as

specified in 4.7.3.

3.5.5 Insulation resistance. Insulation resistance of the cable at or corrected to 15.6 �C, shall be not less than

5,000 megohms per single conductor mile (see 4.7.4).

3.5.6 Mutual capacitance. The mutual capacitance shall not exceed 0.11 �F per pair mile when tested in

accordance with 4.7.5.

3.6 Insulation repairs and splices. No insulation repairs or splices shall be allowed.

3.7 Workmanship. The cable shall be manufactured in such a manner as to be of uniform quality and free from

defects that will affect life, serviceability, or appearance and shall be in accordance with the applicable portions of 3.2

and 3.3 (see 4.8).

3.8 Recycled, recovered, or environmentally referable materials. Recycled, recovered, or environmentally

preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the

operational and maintenance requirements, and promotes economically advantageous life cycle costs.

3.9 Prepackaging. Each length of cable shall be fully and evenly wound on a reel conforming to MIL-DTL-3241,

type DR-5. Both ends of cable shall be brought out and secured in a position that will permit a continuity check (DC

resistance, see 3.5.3). Each reel with cable shall be overwrapped with one thickness of fiberboard conforming to

ASTM-D4727/D4727M, Type CF, class weather resistant, variety SW, grade V3C, of sufficient length to extend the

full distance between the reel flanges and of sufficient length to overlap the ends by at least 6 inches (152 mm). The

overwrap shall be secured with two bands of flat steel strapping conforming to ASTM D3953, type 1, .5 inch wide by

0.020 inch (12.7 mm by 0.508 mm) thick.

4. VERIFICATION

4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:

a. First article inspection (see 4.2).

b. Conformance inspection (see 4.3).

4.2 First article inspection. Unless otherwise specified in the contract, the first article inspection shall be performed

by the contractor.

4.2.1 Units. The contractor shall furnish five (5) one mile lengths of finished cable WD-16( ) each mile wound on

reel DR-5 as a sample for approval, if required by the invitation for bids or contracts.

4.2.2 Inspection. The first article inspection shall consist of the inspections specified in subsidiary documents

covering the items in 4.4 and the inspections specified in tables I, III and V.

4.3 Conformance inspection. The contractor shall perform the inspections specified in 4.4 and 4.3.1 through

4.3.3. This does not relieve the contractor of his responsibility for performing any additional inspection which is

necessary to control the quality of the product and to assure compliance with all specification requirements.
