European foreword
This document (EN 4681-001:2019) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has
received the approval of the National Associations and the Official Services of the member countries of
ASD, prior to its presentation to CEN.
This document shall be given the status of a national standard, either by publication of an identical text
or by endorsement, at the latest by June 2020, and conflicting national standards shall be withdrawn at
the latest by June 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 4681-001:2017.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
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
The characteristics of the cables, tested according to the methods described hereafter shall comply with
the values given in the product standard.
