This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee ASD-
STAN.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of 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, Türkiye and

European foreword
This document (prEN 2084:2025) has been prepared by ASD-STAN.
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 2084:2018.
— in Table 1, 6.1.34, 6.1.35, 6.1.36 and 6.1.37: the applicability of these tests in prior to delivery:
“On ‘raw materials’ only through Testing or Conductor manufacturer Certificate of Compliance”;
— in Table 1, 6.1.48 (adherence) comments modified to remove the word “minimum” from the phrase:
“Adherence force minimum tolerances: Table 7”;
— editorial improvements and update of the scope to change “single mode fibre core” to
“simplex fibre”.
1 Scope
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.
2 Normative references

4 Materials and construction of cables
4.1 Conductors
They shall conform to EN 2083 and/or EN 4434, unless otherwise specified.
4.2 Finished cables
The insulation material shall present on 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 (unless the acceptable overlap due to a tape wrapped technology) and are able to
accept marking.
Multiconductors assembly shall be cabled according EN 2235.
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.
6 Tests methods
6.1 Single core cables
Single core cables shall be according to Table 1.
