4.1
Conformance inspection.
4.1.1 Inspection equipment. The measuring and testing
equipment shall be as specified on the Index of Inspection

Test methods.
4.2.1 Function firing test procedure. The gun shall be
function fired at a cyclic rate of fire of 1350 and 1650 rpm
using a feeder, recoil adapters, power supply with control
equipment and calibrated drive specified in MIL-DTL-45500. To
calculate the gun torque at minimum cyclic rate of fire, the
steady state rate of fire, and the mean differential pressure
across the drive shall be calculated using the last 50 percent of
the burst excluding stopping time. The calculated rate of fire
shall be 1350 to 1650 rpm.
4.2.2 Interchangeability test. The following groups of
nonmating parts shall be utilized in the interchangeability test:
