the inflation assembly shall be examined and shall not have shattered or fragmented. The empty
cylinder shall be removed and the top examined for the location of the puncture (see 3.5.4).
4.7 Temperature exposure.
4.7.1 High temperature. The inflation assembly without the copper shear wire shall be
subjected to a temperature of 160 + 5 degrees Fahrenheit (71 + 3 degrees Centigrade) in
accordance with MIL-STD-810 method 501.2, Procedure 1 (storage), for 48 + 1/2 hours. The
inflation assembly shall then be immediately removed and immersed in water having a temperature
of 60 + 3 degrees Fahrenheit (15 + 2 degrees Centigrade) and a conductivity of 100+50/ 10
microsiemens. The assembly shall then conform to the requirements of paragraph 3.5.4. After a
minimum of' 1/2 hour under water the inflation assembly shall be removed and examined. There
shall be no evidence of cracks, flaking, deformation, distortion, splintering, fragmentation or other
defects (see 3.10).
4.7.2 Low temperature. The inflation assembly with the copper shear wire installed shall be
subjected to a temperature of minus 20 + 2 degrees Fahrenheit (minus 28 + 1 degrees
Centigrade) for a minimum of 48 + 1/2 hours in accordance with MIL-STD-810 method 5022,
Procedure I, (storage). The inflation assembly shall then be immediately removed and immersed
in water having a temperature of 32 + 2 degrees Fahrenheit (zero +/ degree Centigrade) and a
conductivity of 100 +50/-10 microsiemens The inflation assembly shall conform to the
requirements of paragraph 3.5.4. After being immersed for a minimum of 1/2 hour, the inflation
assembly shall be removed from the water and examined. There shall be no evidence of cracks,
flaking, deformation, distortion splintering, fragmentation, or other flaws nor shall the assembly be
activated The assembly shall then conform to the requirements of 3.5.2 and 3.5.4 (see 3.10).
4.8 Vibration and explosive atmosphere.
Vibration.
4.8.1
The inflation assembly shall be subjected to vibration conditions in
accordance with MIL-STD-167-1, type I. After testing, the assembly shall show no evidence of
nicks, cracks, loose particles, or other flaws, nor shall the assembly be activated. The assembly
shall then conform to the requirements of 4.9.2.
4.8.2 Explosive atmosphere The inflation assembly shall be subjected to an explosive
atmosphere test in accordance with MIL-STD-81O, Method 511.2, Procedure I, with test altitude
being sea level and ambient air temperature of 125 + 5 degree Fahrenheit (52 + 3 degrees
centigrade.)
NOTE No identification plate reflecting testing information is required to be
attached to the inflator after testing is completed.
4.9 Rain. The inflation assembly shall be subjected to the rain water test in accordance with
MIL-STD-810, Method 506.2, Procedure II, with rain water having a conductivity of 350 + 35
