MIL-V-82444A(OS)
* 4.4.4.9 High temperature operating.  Before testing, the valve,
installed in its test chamber in the ready condition, shall be condi-
0
tioned at a temperature of +140 F  5 F for a period of 1 hour.  The
valve shall then be operated in accordance with and meet the requirements
of 4.4.4.11 at an environmental temperature of +140F 5 F.  The valve
shall thereafter meet the requirements of 4.4.4.12 through 4.4.4.14.
4.4.4.10 No-fire current.  The valve (or sample squib) shall be sub-
jected to a current of 0.2 0.02 ampere maximum for a period of 5 minutes
minimum, in accordance with Figure 2, and shall not fire.  Thereafter,
the valve (or sample squib) shall be capable of meeting the requirements
of 4.4.4,11.
4.4.4.11 Firing current.  The valve (or sample squib) shall fire when
subjected to a current of 2.0 0.2 ampere dc for 5 0.5 milliseconds
in accordance with Figure 2.
4.4.4.12 Visual inspection, after firing.  After firing, the valve case
shall be inspected and shall show no evidence of permanent distortion.
* 4.4.4.13 Flow, after firing. Upon actuation, the ram shall completely
sever the integral metal diaphragm permitting full flow through the valve.
The flow through the actuated valve shall be at least 5 standard cubic
feet per minute of dry gaseous nitrogen with 300 5 psig applied to the
inlet at 70 5F.
4.4.4.14 Leakage at operating pressure, inlet and outlet ports, after
firing. With the squib remaining in the valve body after firing, the
valve shall be subjected to a pressure of 4500 200 psig, using dry
inert gas.  Pressure shall be applied to the inlet and outlet ports for
a period of 5 minutes with the valve submerged in water.  There shall be
no evidence of leakage.  The pressure shall be released and the valve
inspected for evidence of permanent distortion.
* 4.4.5 Test data sheets.  All test data shall be recorded on a date
sheet by the supplier and maintained as part of the inspection records.
In addition to the data requirements of 4.5.8, the data sheets shall contain.
but are not limited to, the following information:
