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.
The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide recommendations for marking wire and cable insulations to meet legibility requirements. This information is generic and applies to any type of wire marking system, such as an ultraviolet (UV) laser marking system or an inkjet or other ink based wire marking system. This ARP is limited to the legibility of human-readable characters and does not address bar code or other machine-readable symbols. In this ARP, the term wire refers to jacketed cables and fiber optic cables in addition to individual wires. This ARP defines the factors that affect the legibility of markings on wiring. Two generic types of variables affect legibility: stimulus variables and environmental variables. Stimulus variables are those factors involving the mark itself.
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.

Ultraviolet (UV) laser marking for aerospace wire and cable is now a well established and accepted process. The purpose of this report is to provide general information on the technical basis of marking systems that apply UV laser energy to the wire surface. This includes materials for UV laser marking; the key characteristics of UV lasers suitable for this application, in terms of the mark process requirements and operational requirements; the various types of UV lasers which meet the general requirements for wire marking; and the generic components of UV laser marking systems. Subjects beyond the scope of this report include other wire marking systems not utilizing UV lasers; legibility; and contrast measurement.
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.
