applicable test(s) specified. Connectors shall be mounted on the vibration table by normal means. All
contacts shall carry a test current of 100 milliamperes maximum and shall be continuously monitored for
discontinuities throughout the test. A detector capable of detecting any discontinuities in excess of 1
microsecond shall be used. All series I and II connectors shall have the wire bundles clamped to fixed
points at least 8 inches (203.2 mm) behind the connector. All series I, III, and IV plugs shall have an
accessory load fixture in accordance with figure 24 attached during vibration.

Means may be provided to relieve hermetic solder termination’s, and jumper wires may be used between
contacts.
motion from 10 to 2,000 Hz in each of three mutually perpendicular axes. The level of vibration shall be a
velocity of 254 mm/sec from 10-50 Hz; 1.5 mm double amplitude from 50-140 Hz, and 60 G from 140-2,000
Hz. The entire frequency range from 10-2,000 Hz and back shall be traversed in 20 minutes. The vibration
shall be applied for a duration of 12 hours in each of the three mutually perpendicular axes for a total of 36
hours. Each axis of vibration shall be accomplished by vibrating for 4 hours at ambient room temperature,
4 hours at -55 C ±5 C, and 4 hours at +175 C ±5 C for classes J, X and W, and 200 C ±5 C for classes C,
F, G, H, K, N, M, R, S, and Y.
