This European Standard was approved by CENELEC on 2010-07-01. CENELEC 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.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 96/357/FDIS, future edition 2 of IEC 61558-2-3, prepared by IEC TC 96,
Transformers, reactors, power supply units and similar products for low voltage up to 1 100 V, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61558-2-3 on
2010-07-01.
This European Standard supersedes EN 61558-2-3:2000.
The main changes consist of updating this part in accordance with EN 61558-1:2005.
This part has the status of a group safety publication in accordance with IEC Guide 104:1997, The
preparation of safety publications and the use of basic safety publications and group safety publications.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
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) 2011-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-07-01
This part is intended to be used in conjunction with the latest edition of EN 61558-1 and its amendments.
It is based on the second edition (2005) of that standard.
This part supplements or modifies the corresponding clauses in EN 61558-1, so as to convert that
publication into the EN standard: Particular requirements and tests for ignition for gas and oil burners.
A list of all parts of the EN 61558 series, under the general title: Safety of transformers, reactors, power
supply units and combinations thereof, can be found on the CENELEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing standards
in this series will be updated at the time of the next edition.
Where a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is
reasonable. Where this part states "addition", "modification" or "replacement", the relevant text of Part 1 is
to be adopted accordingly.
In this part, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matters: in smaller roman type.
In the text of this part, the words in bold are defined in Clause 3.
Subclauses, notes, figures and tables additional to those in Part 1 are numbered starting from 101;
supplementary annexes are entitled AA, BB, etc.
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 2006/95/EC.
Annex ZA has been added by CENELEC.

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 collaborate
