A failure is defined as the inability of the gun system to perform within the
requirements of this specification (see 6.3).
4.3.4 Test conditions and equipment. All firing tests shall be
accomplished with the gun system affixed to a Government approved mount by its
normal means of attachment. The mount shall have a rigidity so that not more
than 4mm (0.166 inch) deflection occurs in gun fire recoil. Torsional deflection
of the mount shall not degrade accuracy or dispersion. The contractor shall
furnish the applicable measuring devices and instrumentation to measure and
record test data. Calibration of the test equipment shall be in accordance with
MIL-STD-45662. The contractor shall interface the gun system with the necessary
chuting and necessary anmunition storage capacity to complete each test. The
chuting and storage device shall be provided by the contractor. The contractor
shall provide all-necessary supplies and services except GFP to accomplish the
testing specified herein. Unless otherwise specified, all gun system test firing
shall be with TP-T ammunition. Unless otherwise specified herein, all tests
shall be conducted under environmental conditions existing at the test site.

of MIL-STD-810, Method 500.1, Procedure II, to an altitude of 5,200 m. While at
this pressure altitude, the gun system shall be fired or cycled in one l-second
burst. The gun system shall meet the requirements of 184.108.40.206 and 220.127.116.11.
18.104.22.168.2 High temperature. The gun system, when subjected to the high
temperature environment specified in MIL-STD-810, Method 501.1, Procedure I,
with the test chamber at a temperature of 71C for 4 hours, shall have the heat
input removed and shall fire or cycle one 1-second burst. After the gun system
