188.8.131.52.11.1 Design Shock. The gun system shall be subjected to the basic
design shock test of MIL-STD-810, Method 516.2, Procedure I, Figure 516.2-2,
amplitude, duration c, for three shocks in each direction along the gun's three
mutually perpendicular axes, for a total of 18 shocks. After this test, the gun
system shall cycle dummy ammunition in two 1-second bursts. The gun system shall
meet the requirements of 184.108.40.206 and 220.127.116.11,1.
18.104.22.168.11.2 High impact. The gun system shall be subjected to the high
impact test of MIL-S=901, Grade B. The gun system shall meet the requiremnts of
22.214.171.124 Recoil force. A separate test is not required. Sufficient data
shall be accumulated during other firing tests to determine the gun recoil loads.
The data shall be examined for compliance with 126.96.36.199.
188.8.131.52 Muzzle blast pressure. A separate test is not required. Sufficient
data shall be accumulated during other firing tests to determine the gun muzzle
blast pressure pattern. The data shall be examined for compliance with 184.108.40.206.
220.127.116.11 Electronmagnetic compatibility tests. The gun system shall be
tested in accordance with the interference Control plan specified herein and MIL-
STD-462 to determine if the system meets the requirements of 3.3.2.
18.104.22.168 Reliability. Data taken during the tests of 22.214.171.124 shall be
analyzed to determine if the gun system meets the requirements of 3.2.3.
126.96.36.199 Durability. One gun system shall be subjected to a 30,000 round
firing test during which nonmaintenance other than scheduled maintenance shall be
performed, and no unscheduled parts replacement shall be made. During the test a
minimum of three complements shall each be fired in a continuous burst. The
remaining rounds shall be fired in accordance with the burst firing schedule of
188.8.131.52. The test data shall be analyzed for compliance with the requirements of
184.108.40.206, 3.2.3, and 220.127.116.11. Bore erosion criteria data will be collected and
developed during this test.
18.104.22.168 Maintainability. The maintainability requirements of 3.2.4 shall
be demonstrated in accordance with MIL-STD-471, Method 9.
22.214.171.124 Safety. A separate test is not required. Data taken during other-
firing tests shall be analyzed to determine if the gun system meets the require
ments of 126.96.36.199 through 188.8.131.52.
184.108.40.206 Extended burst firing. The gun system shall be loaded with 300
rounds of TP-T ammunition. The gun system shall be fired in a single burst until
the ammunition is exhausted. The gun system and test data shall be examined for
compliance with 220.127.116.11, 18.104.22.168, 22.214.171.124, and 126.96.36.199.
5.1 Preservation, packaging, and packing. Unless otherwise specified in the
contract or purchase order (see 6.2), the gun system shall be preserved in a
