7、ection of wire, shielding,outer protective coverings, and connectors and associated hardware, and (2) wiringharness and cable assembly fabrication, for use in the design and installation of acomplete cable system in combat and tactical vehicles. IThe citeria for inclusion of wire, shielding, sheathi
8、ng, and connectors andassociated hardware in this standard are as follows:a.b.c.d.e.The wiring and associated materiala shall be suitable for uaein military vehicles.The wiring and associated materials shall be covered byGovernment specifications.The wiring and associated materials shall be availabl
9、e forprocurement.The wiring and associated materials shall be suitable formultiple applications.The wiring and associated materials shall be approved forlisting or listed on applicable qualified products lists (QPL).This standard, due to its complexity and numerous subjects, has beenbroken down into
10、 sections. These sections are labeled numerically and areconsecutive in the step-by-step process by which a complete cable systemwould be designed. Each section is structured to stand alone to allow thedesigner accesa to information on specific subjects.iiiProvided by IHSNot for ResaleNo reproductio

This standard covers the selectlon and installation ofwiring and wiring devices used in combat and tactical vehicles.1.2 Purpose and application. This standard establishes designrequirements for wiring combat and tactical vehicles. Althou
40、gh many of therequirements are written as mandatory and must be considered as such, thereis also considerable material which is intended to denote optional,preferential, or guidance-type requirements. In interpreting the materialcontained herein, it is intended that the philosophy of the entire docu
