4.6.10 Firing rate test. The FIRING RATE switch on the control
panel shall be rotated to the HIGH or LOW rate of fire and the weapon
system fired. The rates of fire shall be tested for compliance with
3.3.5 and 3.3.6. Interpolation of rate requirements for systems tested
below 40F is acceptable.
4.6.11 Burst limiting test. The weapon system shall be fired at
the high rate in four burst limits to determine compliance 3.3.7.
4.6.12 Field of fire test. The mount and gun shall be operated
through all ranges of elevation and azimuth to determine compliance
with 3.3.8 The elevation electrical limit switches shall prevent the
weapon system from being driven into the mechanical stops.
4.6.13 Slewing rate and acceleration test. The mount and gun
shall be slewed in all operational modes. The slew rate and accereration
shall be as specified in 3.3.9 and 3.3.1O.
4.6.14 Rounds counters test. The rounds counters shall be tested
-
for accurate counting of rounds as specified in 3.3.11. The weapon
system shall be fired in bursts as specified in 3.3.7a through 3.3.7d.
4.6.15 Stall and stop test. The weapon system shall be operated
through ranges of elevation and azimuth rotation to determine compliance
with 3.3.8) 3.3.12 and 3.3.14. The gun mount shall be driven into the
limit switch and mechanical stops at maximum slew rate. The mount shall
not be damaged.
4.6.16 Firing interrupter test. The firing interrupter assembly
(see 3.3.13) shall be visually and manually inspected for secure and
correct assembly in the system. Using Government approved test equipment
and by simulated firing of the system, automatic interruption of firing
shall be cht'eked for each 20 segment of azimuth and each 5 increment
of elevation within each segment of azimuth. To assure maximum safety
for simulated firing, set controls for interrupted firing and ground mode.
Set rods for alternately firing in 20 segments and rotate turret through
azimuth for each 5 increment of elevation. Observe that the firing
voltage test lamp is "off" or "on" during alternate 20 segments corre-
sponding to the rod settings in the firing interrupter assembly. Failure
of the firing interrupter to follow the rod settings shall be cause for
readjustment of the interrupter assembly and retest.
4.6.17 Operational capability test. The weapon system shall be
operated as described in 3.3.1, 3.3.5 and 3.3.6 to determine compliance
with the operational capability of the weapon system as specified in
3.3.15.
4.6.18 Declutching feeder test. The weapon system shall be fired.
The ammunition shall be fed to the cannon in compliance with 3.3.16.
