4.5.12 Vibration. The vibration test shall be conducted in accordance with
MIL-STD-81O and the detail specification. The minimum vibration level shall
be 10 g's acceleration between 74 and 2000 Hertz. All pump mounted switches
and relays shall be monitored during the test for chatter, bounce, or varia-
tions in contact resistance.
4.5.13 Shock. The shock test shall be conducted in accordance with MIL-STD-81O,
Method 516, Procedure III. The mounting jig used in this test shall simulate
the aircraft mount in mass and rigidity.

and extreme temperature tests shall be conducted in accordance with
MIL-F-8615.

in performance, nor shall there be any evidence of corrosion beyond
4.5.15 Fungus resistance. A fungus-test shall be conducted in accordance with
MIL-F-8615 if the pump contains any material which may possibly be a nutrient.
The test report shall include a list of all materials used in the pump, whether
this test is conducted or not. The fungus test shall not cause any deteriora-
tion in performance, or dielectric strength.
4.5.16 Endurance test. The endurance test shall consist of 1200 hours of
operations in accordance with the schedule of table 11. The entire test shall
be accomplished without disassembly, adjustment, replacement of any part or
removal of the pump from the test set-up. At the conclusion, the pump shall
