This document specifies the characteristics, test methods, qualification and acceptance conditions of single and multicore electric cables, without jackets, for general purpose with conductors in copper or copper alloy, intended for installation in aircraft circuits. The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding 2 000 Hz. Unless specified by individual product standards the maximum demonstrated A.C. voltage of rating of these cables is 115 V RMS (phase to neutral) and 200 V RMS (phase to phase). They are divided into types, the characteristics of which are given in the product standards. Unless otherwise specified in the product standard, the tests defined in this document apply.

This document specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for rectangular connectors with one or multiple removable modules, intended for use in a temperature range from −55 °C to 175 °C continuous. This family of connectors is particularly suitable for aeronautic use in zones of severe environmental conditions on board aircraft, applying EN 2282. The maximum in-service temperature can be limited by maximum temperature of contacts.

This document specifies a method of measuring the tensile properties of stranded conductors, single strands, solid conductors and braids. When required, it can be used also on insulated wires and cables after removing the insulation. It is intended to be used together with EN 3475-100.

This document specifies the dimensions, linear resistance, mechanical characteristics, construction and mass of lightweight conductors, normal and tight tolerances, in copper or copper alloy for electrical cables for aerospace applications. It applies to stranded conductors, with a nominal cross-sectional area of 0,15 mm2 to 14 mm2 inclusive. The conductors for thermocouple extension and fire-resistant cables are not covered by this document.

This document provides instructions on the methods to be used when designing, selecting, manufacturing, installing, repairing or modifying the aircraft electrical and optical interconnection networks, also called Electrical Wiring Interconnection System (EWIS), and Optical fibre Interconnection Systems (OFIS), subject to the following limitations: - It is recognized that the installation practices contained in this document do not necessarily represent the full requirements for a safe and satisfactory electrical and fibre optic interconnection system. - In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. However, nothing written in this document overrides the specific requirements of a Design Authority, the Airworthiness Requirements, applicable laws or any regulation from the regulatory authorities, unless a specific exemption has been obtained. This document lists the main relevant European Standards related to EWIS and OFIS in Annex A.
