cleaned, and inspected. All system components shall be degreased with a service approved non-
chlorinated solvent. During reassembly the system shall be restored to serviceable condition by
reconditioning or replacing all worn parts. The test lube shall be applied to all system components
and the gun oiler shall be filled with the test lube.
CAUTION FOR TEST PERSONEL: DO NOT LUBRICATE SEALED BEARINGS AND
RECOIL ADAPTERS WITH TEST LUBRICANT. THESE PARTS ARE PERMANENTLY
LUBRICATED DURING MANUFACTURE WITH A SPECIAL LUBRICANT.
a. The gun system shall be test fired using inert ammunition at ambient conditions 21 ± 6 °C
to verify proper operation. Ambient firing shall consist of one burst of 100 rounds with the high
rate of fire [6,000 shots per minute (SPM)] selected. Steady state firing rate measured during the
burst shall average 6,000 + 1,200 200 SPM. The time required for the system to reach steady
state rate of fire shall be not greater than 0.8 second. After firing the check burst, the weapon and
system shall be visually examined to determine service operability. No lubrication shall be applied
to the system at this time.
b. The entire system shall be cooled to 50 ± 1 °C and stabilized at this level for a minimum
of two hours. The hydraulic power supply shall be operated in the standby mode for five minutes
to warm the fluid. A firing attempt shall then be made (high rate setting selected). The time
required to reach steady state rate of fire shall be not greater than one second.
c. The system shall be heated to 15 ± 2 °C and 60 percent humidity, and maintained for two
hours. After this period, the system shall again be stabilized at 50 ± 1 °C and maintained at this
level for two hours. After operating the power supply for five minutes, the gun system shall be
fired at the high rate of fire. Minimum steady state rate shall be not less than 5,000 SPM. The
time required to reach steady state rate of fire shall be not greater than one second.
d. Conditions in the test chamber shall be returned to ambient. The gun and ammunition
handling system shall be completely disassembled and examined for signs of damage.
4.5.11 Coating appearance. A smooth steel panel, 51 x 102 mm, shall be dipped in the
vertical position into a recently agitated lubricant, removed with a smooth vertical motion, and
examined for lumps, nonhomogeneities, and foreign matter.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD
personnel, these personnel need to contact the responsible packaging activity to ascertain requisite
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activity within the Military Department or Defense Agency, or within the Military
