3.4.14 Torque. The torque required to manually start
rotation of the feeder shaft without ammunition shall be
determined for each feeder.
3.4.15 Solenoid dielectric withstanding voltage. Solenoid
shall withstand 590 to 600 volts root mean square at a frequency
of 50 to 60 Hertz (Hz) for one second without disruptive
discharge or deterioration. Testing shall be as specified in
4.4.3.1, 4.5.1 and Method 301 of MIL-STD-202.
3.4.16 Solenoid operation. The solenoid shall actuate the
clearing guide and position the clearing guide into the feed
position when 25 volts direct current (vdc) is applied to the
solenoid and when the solenoid is de-energized it shall allow the
clearing guide to return to the clearing position under spring
action of the solenoid plunger. Testing shall be as specified in
4.4.3.1 and 4.5.2.
3.4.17 Functioning. The feeder shall operate without
stoppage or breakage of parts attributable to the feeder.
Testing shall be as specified in 4.4.3.1 and 4.5.3. The feeder
shall completely strip all rounds from the links, shall feed the
stripped rounds into the machine gun or approved test equipment
simulating the machine gun, shall eject the empty links from the
feeder, and perform its cleaning function. Links may remain in
the exit chute after firing.
3.4.18 Interchangeability. Unless otherwise specified on
the drawings, all parts shall be interchangeable. (In normal
assembly operations there shall be no objections interposed to
preferential assembly of parts provided that all parts are
dimensionally acceptable.) Feeders and repair parts shall be
capable of meeting the interchangeability tests specified in
4.4.3.2 and 4.5.4.
3.4.19 Endurance. Feeders shall be capable of withstanding
an endurance test of 30,000 rounds with at least 200 clearing
operations without functioning failures (see 3.4.17), or no more
than one clearing malfunction attributable to the feeder and the
replacement of shear pins as a result of a malfunction. Testing
shall be in accordance with 4.4.3.3 and 4.5.5.
3.5 Marking. Each feeder shall be marked in accordance
with the applicable drawings and MIL-W-13855.
3.6 Workmanship. Workmanship shall be in accordance with
the workmanship requirements of MIL-W-13855.
