(total of 18 shock pulses). Thereafter, the firing switch shall show no
damage and shall meet the performance requirements and product characteris-
tics of this specification.
Shock; transportation, storage, and handling. The firing switch,
4.3.2.2
packaged and packed as specified in Section 5, shall be subjected to the
appropriate shock isolation tests specified in OR-11.
4.3.3 Acceleration. The firing switch, mounted as shown on Drawing 1472712
or 1472663, shall withstand 15 plus or minus 2g's acceleration for a period
of not less than 0.2 second in each of three mutually perpendicular axes with
inertial loads in both directions. Thereafter, the switch shall show no
damage and shall meet all the performance requirements and product character-
istics of this specification.
4.3.4
Temperature and humidity
Transportation and storage conditions. The firing switch, packaged
4.3.4.1
as specified in Section 5, shall be subjected to transportation and storage,
temperatures and humidities between minus 65 degrees F and plus 160 degrees F
for a period of 28 days. Thereafter, the switch shall show no corrosion or
damage and shall meet all the performance requirements and product character-
istics of this specification.
4.3.4.2 High temperature operation. The firing switch, less pack and
packaging, shall be placed within a test chamber and the temperature shall
be raised to plus 130 degrees F plus or minus 5 degrees F and maintained at
this temperature for a period of 48 plus or minus 5 hours. At the end of
this test period, and while still at the test temperature, the switch shall
meet all the performance requirements and product characteristics of this
specification.
4.3.4.3 Low temperature operation. The firing switch, less pack and pack-
aging, shall be placed in a test chamber and the temperature shall be lowered
to minus 40 degrees F plus or minus 5 degrees F and maintained at this tem-
perature for a period of 48 plus or minus 5 hours. At the end of this test
period, and while still at the test temperature, the switch shall meet all
the performance requirements and product characteristics of this specifica-
tion.
4.3.5
Operating life
4.3.5.1 Definition of one cycle. One cycle of operation for the firing
switch shall be defined as the discharging of a 4-microfarad (mfd) capacitor
having an initial charge of 150 volts dc through a 5-ohm resistor with one
impact applied to the switch.
