Insulation resistance, squib, before firing. The insulation
3.3.5
resistance,
between the leads of the squib bridge wires and the squib case,
shall be 2
megohms minimum before firing when measurement is made using
a potential
of 500 volts rms at 60 cps.
Auto-ignition.
3.3.6
Low temperature. The squibs, whether separate or assembled
3.3.6.1
into the valve body, shall be capable of withstanding a temperature of
+170 F for 2 hours and shall not self-ignite. Thereafter, the squib or
valve shall meet the operating requirements of 3.3.8.
High temperature. The squibs, whether separate or assembled
3.3.6.2
into the valve body, shall be capable of withstanding a temperature of
+200 F for 8 hours and shall not self-ignite. Thereafter, the squib,
or valve, is not required to meet the operating requirements.
No-fire current. The squib, whether separate or assembled
3.3.7
into the valve body, shall be capable of having a current of 0.2 amperes
D.C. passed through its bridge wire for 5 minutes minimum without igniting.
Thereafter, the squib shall be capable of meeting the operating require-
ments of 3.3.8.
Firing current. The squib, whether separate or assembled into
3.3.8
the valve body, shall fire when subjected to a current of 2 amperes D.C.
for 5 milliseconds.
Ram operation. Upon actuation, the ram shall completely
3.3.9
sever the integral metal diaphragm permitting full flow through the valve.
The distance between the end of the ram and a plane which coincides with
the surface of the valve body end face shall not exceed 0.500 inches.
Configuration.
3.3.10
Dimensions. Dimensions of the valve shall be in accordance
3.3.10.1
with BuWeps Dwg. 2526651 and all documents listed thereon.
Environmental requiremnts. Unless otherwise specified, the
3.4
valve shall be capable of conforming to the performance requirements and
product characteristics of the specification after being exposed to the
environmental conditions specified in this section. For definitions of
ready, operating, and non-operating see 6.3.1, 6.3.2 and 6.3.3
