184.108.40.206.2 Firing during acceleration. Degradation will occur during
firing while subject to high "g" loads. Allowable degradations are shown in
Figure 5 (see 220.127.116.11.10.2).
18.104.22.168.1 Design shock. The gun system shall sustain steady state firing
after being subjected to the design shock test (see 22.214.171.124.11.1).
126.96.36.199.2 High impact shock. When specified in the contract or purchase
order (see 6.2), the gun system shall be tested, and shall show no structural
failures creating a hazard to personnel or equipment. The gun system is not
required to sustain steady state firing after this test (See 188.8.131.52.11.2)-
3.3 Design and construction.
3.3.1 Materials, processes, and parts. Materials, processes, and parts
used shall be of high quality, suitable for the purpose, and shall conform to
applicable military, federal, Aerospace Material Specifications wherever
possible. Particular attention shall be given to the selection of materials,
processes, and parts to facilitate interchangeability, stocking, and maintain-
ability. The number of different types and sizes of consumable bulk maintenance
materials shall be kept to a minimum. Noncritical materials shall be used
wherever practicable when performance, interchangeability, safety or reliability
will not be adversely affected. Specifications and standards for materials,
processes, and parts shall be selected in accordance with the order of precedence
specified in MIL-STD-143.
184.108.40.206 Minimum guaranteed material properties. Minimum guaranteed
material design mechanical properties, as defined in MIL-HDBK-5, or source of
material properties acceptable to the procuring activity, shall be used in
calculating the strength of single structural components, the faulure of which
would endanger personnel or prevent the gun system from accomplishing its
220.127.116.11.1 Recycled, virgin, and reclaimed materials. Without jeopardizing
the intended use of the gun system, determination shall be made that:
a. The use of recycled materials is permissible.
b. An item need not be manufactured from virgin materials.
