4.6.4.6 Humidity. The charging valve shall be subjected to the humidity
test in accordance with MIL-STD-810, Method 507, Procedure I, except four
24-hour cycles shall be substituted for the ten 24-hour cycles. While at test
conditions, the charging valve shall be closed and the outlet port pressurized
to 225 25 psig. The inlet port shall be capped. At the completion of test-
ing, the charging valve shall be visually inspected for damage and corrosion,
and tested in accordance with 4.6.3.2 and 4.6.3.3
Vibration. The charging valve shall be subjected to the following
4.6.4.7
tests.
4.6.4.7.1 General. The vibration test specified herein shall be performed
in each of three mutually perpendicular axes in the order shown. All testing
shall be performed in one axis prior to testing in the next axis. As indi-
cated herein, the charging valve shall be checked for proper operation.
4.6.4.7.2 Charging valve operation. While subjected to vibration, the
charging valve shall be closed and the outlet port pressurized 3000 100 psig.
The inlet port shall be capped. After each axis of vibration is completed,
the charging valve shall be visually inspected for damage and tested in accord-
ante with 4.6.3.2 and 4.6.3.3.
4.6.4.7.3 Mounting techniques. The chargin valve shall be attached to the
vibration exciter table by means of the fixture described in 4.3.f. The
vibration input shall be measured on the fixture at a point adjacent to the
mounting point of the charging valve.
4.6.4.7.4 Sinusoidal test level. The charging valve shall be subjected to
sinusoidal vibration along each of three mutually perpendicular axes. The
frequency shall be percent and the amplitude shall be 5 percent. The test
shall consist of sweeping for 60 minutes in each, axis from t to 2000 Hz, at
one octave per minute in accordance with Table IV.
Sinsuoidal test level.
TABLE IV.
4.6.4.7.5 Random test level. The charging valve shall be subjected to a
random vibration along each of three mutually perpendicular axes. The instan-
taneous random vibration acceleration peaks shall be limited to three times
