1 Scope
This document specifies the characteristics, test methods, qualification and acceptance conditions of
single and multicore electric cables for general purpose with conductors in aluminium or copper-clad
aluminium, intended for installation in aircraft electrical systems.
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 voltage of rating
of these cables is ac 115 V rms phase to neutral and 200 V rms phase to phase and 28 Vdc.
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 standard apply.

4 Materials and construction of cables
4.1 Conductors
They shall conform to EN 4651 or EN 3719 unless otherwise specified.
4.2 Finished cables
The insulation material shall present a uniform circular cross-section throughout the length of the cable.
Covering over the insulation shall be treated and applied in such a manner that the cables present a
smooth appearance and are able to accept marking.
All materials used shall have no corrosive effect upon the conductors and shall not be susceptible to attack
by mould or other micro-organisms.
5 Required characteristics
