(b) Vibration Levels. The sample shall be vibrated in accordance with Table IV. The dwell
time at each integral frequency shall be not less than 5 minutes.
TABLE IV.
Vibration Levels
NOTE : All references to amplitude of vibration refer to maximum displacement of sinusoidal motion
from the position of test, or one half the total excursion,
(c) Resonance dwell. The sample shall be vibrated for not less than 2 hours at the frequency
at which the greatest resonance or discontinuities were noted. If no discontinuity or resonance
occurs, resonance dwell shall be performed at 50 Hz.
4.5.6.1.2 The above schedule shall be completed in each of the three mutually perpendicular
axes.
4.5.6.2 Shock. The cable assembly shall be mated in Torpedo Tube Cable Connector Mk 42 Mod 1
and securely mounted to a shock fixture simulating service conditions as shown in Figure 6. All
circuits shall be wired in series for the purpose of monitoring any discontinuities. The test
specimens shall be subjected to the shock test defined In MIL-S-901 for lightweight equipment.
Three shocks shall be applied parallel to each of the three principal axes as shown in Figure 6.
A total of nine shocks shall be applied. During shock, the series circuit shall be monitored
for discontinuity, using a relay chatter indicator or equivalent. Discontinuities in excess of
100 microseconds shall be considered evidence of failure.
4.5.6.3 Salt water immersion. The cable assembly, mated with Torpedo Tube Door Connector Mk
42 Mod 1, shall be subjected to a 30-day immersion test. The cable assembly shall be attached to
a fixture so that all of the plug end (tube door end) will be immersed in sea water. The cable
assembly shall be immersed for not less than 16 hours and removed for a period of not less than
8. hours. The sequence shall be repeated 30 times. No fresh water rinse will be permitted during
the 30 cycles.
4.5.6.4 Low temperature (operating). The cable assembly shall be mated to Torpedo
Tube Cable
Connector Mk 42 Mod 1 and mounted in the test chamber. The chamber temperature shall
be lowered
to +28 degrees F 5 degrees F (-23C) and maintained for a period not less than 48
hours. At
the end of this time and while still at the test temperature, the test specimen shall
be sub-
jected to the tests of 4.5.5.2, 4,5.5.3, and 4.5.2.
4.5.6.5 High temperature (operating). The cable assembly shall be mated to Torpedo Tube
Cable Connector Mk 42 Mod 1 and mounted in the test chamber. The chamber temperature shall be
raised to 130 degrees F 5 degrees F (543C) and maintained for a period not less than 48 hours.
At the end of this time and while still at the test temperature, the test specimen shall be
subjected to the tests of 4.5.2, 4.5.5.2, and 4.5.5.3.
4.5.6.6 Temperature and humidity (operating). The test unit shall consist of the mated assem-
bly of the "B" torpedo control cable Mk 7, one cable connector Mk 42 Mod 1, and one "A" cable
