microsiemens with a fall rate of four (4) inches per hour. After testing, the assembly shall show
no evidence of nicks, cracks, loose particles, or other defects, nor shall the assembly be activated.
The assembly shall then conform to the requirements of 3.5.2 and 3.5.4 (see 3.8).
4.10 Salt fog. The inflation assembly shall be subjected to the conditions of salt fog test in
accordance with MIL-STD-81 O, Method 509.2, Procedure I. Test duration is to be for a constant
48 hours salt fog and then 48 hours drying. After testing, the assembly shall show no evidence of
nicks, cracks, loose particles, or other defects, nor shall the assembly be activated. The assembly
shall then conform to the requirements of 3.5.2 and 3.5.4 (See 3.11).
4.11 Humidity. The inflation assembly shall be subjected to the renditions of the humidity
resistance test in accordance with MIL-STD-810 Method 507.2, Procedure III using the
temperature/humidity cycle from figure 507-2-3 of the test method. After testing, the assembly shall
show no evidence of cracks, flaking, loose particles, deformation, distortion or any other defects,
nor shall the assembly be activated. The assembly shall then conform to the requirements of 3.5.2
and 3.5.4 (see 3.11).
4.12 Hydrostatic pressure A discharged carbon dioxide cylinder shall be inserted in the
inflation assembly with a maximum torque of 20 inch pounds and the copper shear wire shall be
installed. The assembly shall be subjected to a hydrostatic pressure of 1500 pounds per square inch
(lb/in2) applied to the outlet of the inflation assembly for a minimum of 5 minutes. The inflation
assembly shall then be inspected and there shall be no evidence of leakage or deformation of the
body. After testing the assembly shall conform to the requirements of 3.5.2 and 3.5.4 (see 3.12).
4.13 Differential pressure The inflation assembly shall have the outlet hole for escape of
pressurized gas blocked off fix this test The inflation assembly, equipped with a filled carbon
dioxide cylinder, shall be positioned in a test chamber and subjected to three cycles of surge air
pressure, of 40 + 2 lb/in2 for a duration of 50 + 20 milliseconds, to simulate blast conditions. The
assembly shall not show any evidence of damage or function inadvertently. After testing the
assembly shall then conform to the requirements of 3.5.2 and 3.5.4 (see 3.13).
4.14 Electromagnetic radiation. The inflation assembly shall be subjected to electromagnetic
environment level in accordance with MKL-STD-1385, table I. After testing the assembly shall
show no evidence of cracks, deformation, distortion, or any 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 3.14).
4.15 Impact The inflation assembly shall be subjected to the following test. A filled carbon
dioxide cylinder shall be fully installed in the inflation assembly. The assembly shall be free fall
dropped from a minimum height of 4 feet onto a fixed steel plate, twice on each face. After
testing, there shall be no evidence of cracks, deformation distortion, splintering fragmenting or
any 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 3.15).
