Shelf Test: Capacitors shall withstand a shelf test for 5000 hours at a temperature of + 85°C, with no voltage applied. 9.1 Following the shelf test, the leakage current shall meet the initial requirement; the dissipation factor shall not exceed 150% of the initial requirement; the capacitance change shall not exceed ± 5%. 10. Vibration Tests: Capacitors shall be subjected to vibration tests in accordance with the following criteria. 10.1 Capacitors shall be secured for test by means of a rigid mounting using suitable brackets. 10.2 Low Frequency Vibration: Vibration shall consist of a simple harmonic motion having an amplitude of 0.03" [0.76] and a maximum total excursion of 0.06" [1.52], in a direction perpendicular to the major axis of the capacitor. 10.2.1 Vibration frequency shall be varied uniformly between the approximate limits of 10Hz to 55Hz during a period of approximately one minute, continuously for one and one-half hours. 10.2.2 A cathode ray oscilloscope or other comparable means shall be used in determining electrical intermittency during the final 30 minutes of the test. The AC voltage applied shall not exceed 2 volts rms. 10.2.3 Electrical tests shall show no evidence of intermittent contacts, open circuits or short circuits during these tests. 10.2.4 Following the low frequency vibration test, capacitors shall meet the original requirements for leakage current and dissipation factor; capacitance change shall not exceed ± 5% of the original measured value. 10.3 High Frequency Vibration: Vibration shall consist of a simple harmonic motion having an amplitude of 0.06" [1.52] ± 10% maximum total excursion or 20 g peak, whichever is less. 10.3.1 Vibration Frequency shall be varied logarithmically from 50Hz to 2000Hz and return to 50Hz during a cycle period of 20 minutes. 10.3.2 The vibration shall be applied for 4 hours in each of 2 directions, parallel and perpendicular to the major axis of the capacitors. 10.3.3 Rated DC voltage shall be applied during the vibration cycling. 10.3.4 A cathode ray oscilloscope or other comparable means shall be used in determining electrical intermittency during test. The AC voltage applied shall not exceed 2 volts rms. 10.3.5 Electrical tests shall show no evidence of intermittent contacts, open circuits or short circuits during these tests. 10.3.6 There shall be no mechanical damage to these capacitors as a result of these tests. 10.3.7 Following the high frequency vibration test, capacitors shall meet the original limits for capacitance, dissipation factor and leakage current. 11. Acceleration Test: 11.1 Capacitors shall be rigidly mounted by means of suitable brackets. 11.2 Capacitors shall be subjected to a constant acceleration of 100g for a period of 10 seconds in each of 2 mutually perpendicular planes. 11.2.1 The direction of motion shall be parallel to and perpendicular to the cylindrical axis of the capacitors. 11.3 Rated DC voltage shall be applied during acceleration test. 11.3.1 A cathode ray oscilloscope or other comparable means shall be used in determining electrical intermittency during test. The AC voltage applied shall not exceed 2 volts rms. 11.4 Electrical tests shall show no evidence of intermittent contacts, open circuits or short circuits during these tests. 11.5 There shall be no mechanical damage to these capacitors as a result of these tests. 11.6 Following the acceleration test, capacitors shall meet the original limits for capacitance, dissipation factor and leakage current. 10. Shock Test: 12.1 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. 12.1.1 Test equipment shall be adjusted to produce a shock of 100g peak with a duration of 6 mS and a sawtooth waveform at a velocity change of 9.7 feet/second. 12.2 Capacitors shall be subjected to 3 shocks applied in each of 3 directions corresponding to the 3 mutually perpendicular axes of the capacitors. 12.3 Rated DC voltage shall be applied to capacitors during test. 12.3.1 A cathode ray oscilloscope or other comparable means shall be used in determining electrical intermittency during test. The AC voltage applied shall not exceed 2 volts rms. 12.4 Electrical tests shall show no evidence of intermittent contacts, open circuits or short circuits during these tests. 12.5 There shall be no mechanical damage to these capacitors as a result of these tests. 12.6 Following the shock test, capacitors shall meet the original limits for capacitance, dissipation factor and leakage current. |
