Aerospace series - Testing of aircraft wiring

This document specifies: — the tests for finished wiring, including connectors and, if necessary, terminals, terminal ends, junction boxes, circuit breakers, etc.; — the requirements for verification of aircraft electrical wiring; — continuity of circuits; — dielectric strength; — insulation resistance; — partial discharge for operating voltages above 230/400 V a.c. (see also TR 4907 ). These tests do not concern equipment installed in the aircraft (see operation of systems) and do not apply to the wiring used in instrumentation.

Aerospace series - Wire and cable marking process, UV Laser

This document is applicable to the marking of aerospace vehicle electrical wires and cables using ultraviolet (UV) lasers. This document specifies the process requirements for the implementation of UV laser marking of aerospace electrical wires and cables and fibre optic cables to achieve an acceptable quality mark using equipment designed for UV laser wire marking of identification codes on aircraft wire and cable subject to EN 3475 100, Aerospace series — Cables, electrical, aircraft use — Test methods — Part 100: General. Wiring specified as UV laser markable, and which has been marked in accordance with this document, will conform to the requirements of EN 3838. This document is applicable to the marking of airframe electrical wires and cables using ultraviolet (UV) lasers. The laser process practices defined in this document are mandatory.
