MIL-DTL-55036C
4.6.8 Core wrap. Cable shall be inspected for compliance with requirements of 3.1.8.
4.6.9 Inner jacket. Cable shall be inspected for compliance with the requirements of 3.1.9.
4.6.10 Braid. Cable shall be inspected for compliance with the requirements of 3.1.10.
4.6.11 Outer jacket. Cable shall be inspected for compliance with the requirements of 3.1.11.
4.6.11.1 Tubing test of outer jacket. Six specimens of the jacketed cable shall be wound tightly on a
mandrel having a diameter of 0.625+0.005 inches (1.59+.13 mm) for 5 close turns. The ends shall be
anchored securely and the specimen placed in an oven maintained at a temperature of 120+1 °C for
1 hour. The specimens shall meet the requirements of 3.1.11.1.
4.6.11.2 Physical test of jacket before aging. The jacket shall be tested for compliance with the
requirements of 3.1.11.2.
4.6.11.3 Physical test of jacket after aging. Six samples of the jacket shall be tested for compliance
with the requirements of 3.1.11.3. Aging shall be performed as follows: Place the specimen in an air
oven, conforming to the requirements of ASTM D573, and maintain at a temperature of 80+1 °C for a
period of 14 days, and follow with a cooling period of at least 24 hours at room temperature.
4.6.12 Identification marking. Cable shall be inspected for compliance with the requirements of 3.1.12.
4.7 Electrical tests (see 3.2).
4.7.1 Direct current resistance. Each pair of cable length under test shall be tested for compliance with
the requirements of 3.2.1.
4.7.2 Dielectric strength. The insulation shall be capable of withstanding for not less than 3 seconds a
dc potential of 3.0 kV or an ac potential of 2100 V rms applied between each conductor and the remaining
conductors connected to the braid (see 3.2.2).
4.7.3 Insulation resistance. Immediately following the dielectric strength test, the insulation resistance
between each conductor in turn and the remaining conductors connected to the braid and grounded shall
meet the requirements of 3.2.3. In performing the insulation resistance test, an electromotive force no
less than 100 V shall be used, the conductors being maintained negative with respect to the ground. The
insulation resistance shall be computed form the galvanometer deflection obtained after an electrification
of 1 minute. As an alternate, a direct reading insulation resistance bridge may be used. In making the
insulation resistance test, the test may be terminated in less than 1 minute if the galvanometer has
ceased fluctuating and the reading indicates the required minimum insulation resistance has been
obtained. However, tests results on 5 percent of the lengths after 1 minute electrification shall be
recorded to permit a continuous check on quality.
4.7.4 Conductor resistance unbalance. Each cable length shall be tested for compliance with the
st
requirements of 3.2.4. One pair from the center layer, 2 pairs from the 1 layer, and 3 pairs from the
nd
2 layer shall be selected at random and tested for conductor resistance unbalance.
4.7.5 Mutual capacitance. Each cable length shall be tested for compliance with the requirements of
st
nd
3.2.5. One pair from the center layer, 2 pairs form the 1 layer, and 3 pairs from the 2 layer shall be
selected at random and tested for mutual capacitance. The capacitance shall be measured at a
temperature not lower than 60 °F. If the cable, when measured at a temperature higher than 60 °F, fails
to meet the requirements, no correction factor may be applied. In such case, the cable may be retested
