This SAE Aerospace Recommended Practice (ARP) identifies the minimum requirements for the testing of insulated electrical wiring for on-aircraft, aeronautical and aerospace applications. The testing requirements defined herein, ensure that a wire fault can be found safely when using a high potential voltage tester (hipot). This test is intended to aid in finding a breach in the wire insulation, and not for the identification of the resistance of the insulation. The test method defined herein is limited to equipment which ia able to control and limit the DC output to 1500 VDC maximum. This type of wire dielectric tester is typically designed to trip on current leakage and not necessarily on arc detection. This test method is solely designed to identify gross/large wire insulation damage or degradation. For additional related information on this topic and related test methods, refer to the documents cited in Section 2.
This standard is applicable to manual soldering and machine soldering processes utilizing controlled soldering devices, for electrical connections for wiring and cabling used in aerospace vehicles. Description of a component or device herein is not to be construed as authorizing the use of the component or device.
This specification establishes the performance requirements for the identification of wire and cable by indirect markings that have been applied to electrical insulating materials including heat shrink sleeving, wrap around labels and “tie-on” tags as well as any other types of materials used for indirect marking. This specification covers the processes used to mark these materials, including impact ink marking, thermal transfer, hot stamp, and lasers, etc. This specification does not cover the direct marking on insulated electrical wires and cables.
This specification applies to complete cable assemblies (using either molded on or attachable plugs) used to connect external electric power to aircraft and to attachable plugs used as replacement for plugs damaged in service.
This SAE Aerospace Information Report (AIR) discusses the often overlooked relationship between hot stamp marking and the environmental conditions that contribute aircraft wiring problems and discusses current beliefs of military service experts, regulatory agencies and industry standard writing bodies about the potential hazards imposed by the hot stamping process.
