Foreword
The text of document 20/718/FDIS, future edition 3 of IEC 60228, prepared by IEC TC 20, Electric cables,
was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60228 on
2004-12-07.
A draft amendment, prepared by the Technical Committee CENELEC TC 20, Electric cables, was submitted
to the formal vote and was approved by CENELEC for inclusion into EN 60228 on 2004-12-07.
This European Standard supersedes HD 383 S2:1986 + A1:1989 + A2:1993.
The principal changes with respect to HD 383 S2 are
– addition of a definition for nominal cross-sectional area;
– an increase in the range of conductor sizes in Tables 1 and 2;
– addition of a note that solid aluminium alloy conductors, having the same dimensions as aluminium
conductors, will have a higher resistance;
– strengthening of the recommendations for dimensional limits of compacted stranded copper
conductors.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-12-01
Annex ZA, Special national conditions, has been added by CENELEC.
The contents of the corrigendum of May 2005 have been included in this copy.

Endorsement notice
The text of the International Standard IEC 60228:2004 was approved by CENELEC as a European
Standard without any modification.

Special national conditions
Special national condition: National characteristic or practice that cannot be changed even over a long
period, e.g. climatic conditions, electrical earthing conditions. If it affects harmonization, it forms part of the
European Standard.
For the countries in which the relevant special national conditions apply these provisions are normative, for
other countries they are informative.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60228 has been prepared by IEC technical committee 20: Electric
cables.
This third edition cancels and replaces the IEC 60228 (1978), its Amendment 1 (1993) and its
first supplement, IEC 60228A (1982).
The principal changes with respect to the previous edition are as follows:
a) the consolidation of material from IEC 60228A;
b) addition of a definition for nominal cross-sectional area;
c) an increase in the range of conductor sizes in Tables 1 and 2;
d) addition of a note that solid aluminum alloy conductors, having the same dimensions as
aluminum conductors, will have a higher resistance;
e) strengthening of the recommendations for dimensional limits of compacted stranded copper
conductors.

The text of this standard is based on the following documents:
FDIS Report on voting
20/718/FDIS 20/737/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
Conductors described in IEC 60228 are specified in metric sizes. Canada at present uses
conductor sizes and characteristics according to the American Wire Gauge (AWG) system and
kcmil for larger sizes as shown below. The use of these sizes is currently prescribed uniformly
across Canada for installations by sub-national regulations. IEC TC 20 cable product standards
do not prescribe cables with AWG/kcmil conductors.
