holes, slots, radii or chambers missing.
Four power (4x) magnification may be
used in performing visual examination for such defects as burrs and foreign
matter.
The roughness comparison specimens prescribed in ANSI B46.1 shall be use
as a basis of comparison for surface roughness (finish) determination.
4.6.2 Hiqh temperature
operation.
The launcher shall be placed In a
conditioning chamber at 160
5F for a period of not less than 4 hours and not
greater than 16 hours.
The
battery shall be removed from the electronics
enclosure before performing
this test.
4.6.3 Low temperature operation.
The launcher shall be placed in a
conditioning chamber at -40 5F for a period of not less than 4 hours and not
greater than 16 hours.
The battery shall be removed from the electronics
enclosure before performing this test.
4.6.4 Temperature and humidity. A temperature and humidity test shall be
performed on the launcher in accordance with MIL-STD-81O, Method 507.3, Procedure
III.
The duration of the test shall be four 24-hour cycles.
4.6.5 Recycle time and amperaqe (M101).
The battery shall be fully charged
for the recycle test.
The voltage from the J5-A, J6-A, J7-A, and J8-A connectors
to the negative side of the battery shall be monitored using a multimeter with an
input impedance of not less than 20,000 ohms per volt (ohms/volt). The firing
switch shall then be activated for each position and the amperage from the
battery shall be monitored using a current meter with an accuracy of not less
than 2 percent of full scale.
4.6.6 Firing Pin penetration (M102). A PVU-3B/E igniter, Drawing 1335AS260
-or a PVU-3A/E.igniter, Drawing 1335AS275, devoid of all explosive materials
except the M42 primer, shall be loaded into the launcher breech. The firing
switch shall be actuated after a capacitor charging interval of 140 10 seconds.
4.6.7 Discharge time and voltage (M103)
The battery shall be fully charged
for the discharge test.
The voltage from the J5-A, J6- A, J7-A, and J8-A
connectors to the negative side of the battery shall be monitored using a
multimeter with an impedance of not less than 20,000 ohms/volt. The enable plug
shall be removed after the system has stabilized at 195 20 volts.
4.7 Inspection of Packaging.
The sampling and inspection of the
preservation, packing, and container marking shall conform to this specification
(see section 5).
PACKAGING
5.
5.1 Preservation. Unless otherwise specified, preservation shall be in
