MIL-R-81202D(AS)
4.6.6.4 Salt fog.  The receiver assembly shall be subjected to the salt fog
test in accordance with MIL-STD-81O, Method 509, Procedure I except that the
duration shall be 50 hours.  All fittings normally connected shall be pro-
tected during climatic conditioning.  The receiver shall be pressurized to 225
+/-25 psig.  At the completion of the test, the receiver assembly shall be
visually inspected for damage, corrosion and discoloration, and tested in
accordance with 4.6.5.2 and 4.6.5.3.
4.6.6.5 Humidity.  The receiver assembly shall be subjected to the humidity
test in accordance with MIL-STD-81O, Method 507, Procedure I, except that four
24-hour cycles shall be substituted for the ten 24-hour cycles. All fittings
normally connected shall be protected during climatic conditioning.  The
receiver assembly shall be pressurized to 225 +/-25 psig.  At the completion of
the test, the receiver assembly shall be visually inspected for damage, corro-
sion and discoloration, and tested in accordance with 4.6.5.2 and 4.6.5.3.
4.6.6.6 Vibration.  The receiver assembly shall be subjected to the vibra-
tion test in accordance with MIL-L-22620 while mounted in a LAU-7 series
launcher.  The receiver assembly shall be pressurized to 3000 +/-1OO psig. After
testing is completed for each axis of vibration, the receiver assembly shall
be visually inspected for damage and tested in accordance with 4.6.5.2 and
4.6.5.3.
4.6.6.7 Impact.  The receiver assembly shall be subjected to three free-
fall drops from a height of five feet while pressurized to 3800 +/-100 psig.
The free-fall height shall be measured from the geometric center of the re-
ceiver assembly to the floor, which shall be a rigid concrete surface. Prior
to each impact, an 8-inch I-beam at least six feet long shall be placed up-
right on the floor (so that one flat side of the I-beam lies on the floor).
The geometric centers of the I-beam and receiver assembly shall be located
in-line vertically, but their longitudinal axes shall be positioned in normal
planes.  Extreme care shall be taken during this test. The unit shall be re-
leased using a remote actuated device and provisions shall be made to allow
remote venting of the pressure immediately after each release.  The attitude
condition for each drop, as referenced to the longitudinal axis (see Figure 1),
shall be as follows:
First impact - aft end down 45 to horizontal.
a.
Second impact - forward end down 45 to horizontal.
b.
Third impact - horizontal.
c.
After each impact, the receiver assembly shall be rotated 120 circumferen-
tially (see Figure I).  There shall be no loss of pressure during this test
and the receiver assembly shall not sustain critical physical damage.  This
test is considered a destructive test (see 3.1.2).
