MIL-DTL-23806B
4.5.2 Jacket spark (applicable to jacketed cable only, see 3.4.1). The cable shall be tested in
accordance with method 6211 of FED-STD-228. The following details shall apply:
a. The test voltage shall be 8,000 V rms at 60 Hertz.
b. The potential shall be applied between the outer conductor and the outer surface of the jacket.
A puncture of the jacket by the applied voltage shall constitute a point of failure. The cable
may be cut at this point, or it may be repaired to the satisfaction of the Government.
4.5.3 Continuity (see 3.4.2). A potential of 6 Volts dc, maximum, shall be applied through an
appropriate indicator, to the inner and outer conductor (conductors) of the cable. The voltage may be
applied to the conductors individually or in series.
4.5.4 Dielectric strength (see 3.4.3). The cable shall be tested in accordance with method 6111 of FED-
STD-228, except that the cable shall not be immersed in water but shall be tested dry. The following
details shall apply:
a. The test shall be performed on completed cable only.
b. The test voltage shall be as specified (see 3.1).
c. The potential shall be applied to the inner conductor with the outer conductor grounded.
4.5.5 Insulation resistance (see 3.4.4). The cable shall be tested in accordance with method 6031 of
FED-STD-228, except that the cable shall not be immersed in water but shall be tested dry. The following
details shall apply:
a. The test shall be performed on completed cable only.
b. The test voltage shall be 200 Volts, minimum.
c. The potential shall be applied to the inner conductor with the outer conductor grounded.
4.5.6 Attenuation (see 3.4.5 ). The attenuation, expressed in decibels (dB) per 100 feet, shall be
measured at a sufficiently low-power level that the resulting temperature rise will be negligible. An
acceptable method for measuring attenuations is as follows:
SIGNAL
GENERATOR
ATTENUATOR
ATTENUATOR
AND
CABLE
DETECTOR
PAD
PAD
CALIBRATED
ATTENUATOR
In the block diagram, a suitable length of cable with an attenuation greater than the measuring accuracy
of the equipment is inserted between the connectors. The signal generator and calibrated attenuator are
adjusted to produce a reasonable indication at the detector, when the detector is tuned. The detector
reading is noted, and the calibrated attenuator output level is recorded. The cable under test is then
withdrawn and the circuit completed with the connectors (or a very short length of cable). With the
detector tuned, the calibrated attenuator is readjusted to reproduce the original reading at the detector and
the attenuator output level is again recorded. Attenuation is then computed as follows:
