MIL-PRF-25370F
deformation or leakage of the inflator valve. After completion of this test, the inflator valve shall
be subjected to the tests specified in 4.7.6.
4.7.6 Salt spray. The inflator valve shall be subjected to a 96-hour salt-spray test in accordance
with the test methods in ASTM-B-117. After the salt-spray test, there shall be no corrosion.
After the completion of the salt-spray test, the inflator valve with a charged cylinder conforming
to MIL-PRF-25369 installed, shall be held in an inverted position with a 20-pound load attached
to the end of the actuator and with the actuator held in the normal position. When the load is
released, the actuator shall operate the piercing mechanism which shall pierce and discharge the
cylinder in not more than two and one-half seconds. The actuator safety restraint shall not be
used to secure the actuator during this test.
4.7.7 Leakage. With the inflator valve mounted on a valve stem with the valve stem cap in
place (see Figure 2), the actuator shall be moved slowly through a normal cycle of operation while
the inflator valve is submerged in water and is subjected to an internal pressure of 2 psi for not
less than 10 seconds. This test shall be repeated except that the internal pressure applied shall be
40 psi. There shall be no evidence of leakage from the inflator valve.
4.7.8 Operation test with cylinder. The inflator valve shall be mounted on a valve stem
conforming to Figure 2 with the valve stem cap in place. A charged cylinder conforming to MIL-
PRF-25369 shall be installed. The inflator assembly shall be held in an inverted position with a
load attached to the end of the actuator and the actuator held in the normal position. The outlet
shall be equipped with a chamber that shall provide between 1.5 and 2.5 psi back pressure on the
inflator valve. The inflator valve and load shall be submerged in water. The load shall be such
that a force of 20 pounds is applied to the actuator. When the load is released, the actuator shall
operate the piercing mechanism which shall pierce and discharge the cylinder in not more than
two and one half seconds. The actuator safety restraint shall not be used to secure the actuator in
this test. No leakage shall be evident during the duration of this test.
4.7.9 Lock. The lock on the installed cylinder (conforming to MIL-PRF-25369) shall be tested
by applying a torque of 60 inch-pounds in a counterclockwise direction to loosen the installed
cylinder. The cylinder shall release with a torque of not less than 30 nor more than 60 inch-
pounds.
4.7.10 Actuator safety restraint. The inflator valve shall be held in an inverted position with a 20-
pound load attached to the actuator. The actuator shall be held in the normal position with the
actuator safety restraint installed. When the load is released, the actuator safety restraint shall not
prevent the actuator from operating the piercing mechanism.
