capacitors shall meet the original limits for
capacitance, dissipation factor and leakage
current.
10.
Acceleration Test:
10.1
Capacitors shall be rigidly mounted by means of
suitable brackets.

acceleration of 100 g for a period of 10 seconds in
each of 2 mutually perpendicular planes.
10.2.1
The direction of motion shall be parallel to and
perpendicular to the longitudinal axis of the
capacitors.
10.3
Rated DC voltage shall be applied during
acceleration test.
10.3.1
An oscilloscope or other comparable means shall
be used in determining electrical intermittency

capacitors as a result of these tests.
10.6
Following the acceleration test, capacitors shall
meet the original limits for capacitance, dissipation
factor and leakage current.
11.
Shock Test:
11.1
Capacitors shall be rigidly mounted by means of
suitable brackets. The test load shall be
distributed uniformly on the test platform to
minimize the effects of unbalanced loads.
11.1.1
Test equipment shall be adjusted to produce a
shock of 100 g peak with the duration of 6 mS and
sawtooth waveform at a velocity change of 9.7 ft./
sec.
11.2
Capacitors shall be subjected to 3 shocks applied
in each of 3 directions corresponding to the 3
mutually perpendicular axes of the capacitors.
11.3
Rated DC voltage shall be applied during test.
11.3.1
An oscilloscope or other comparable means shall
be used in determining electrical intermittency
during tests. The replacement voltage applied
shall not exceed 2 volts rms.

pressure at 28 to 31 inches.
13.2
Capacitors shall be subjected to thermal shock in a
cycle of exposure to ambient air at - 65°C (+ 0°C,
- 5°C) for 30 minutes, then + 25°C (+10°C, - 5°C)
for 5 minutes, then + 125°C (+ 3°C, - 0°C) for 30
minutes, then + 25°C (+ 10°C, - 5°C) for 5 minutes

extensive corrosion, obliteration of marking or
other visible damage.
13.4
