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, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword
The text of document 34C/688/FDIS, future edition 3 of IEC 60923, prepared by SC 34C, Auxiliaries
for lamps, of IEC TC 34, Lamps and related equipment, was submitted to the IEC-CENELEC parallel
vote and was approved by CENELEC as EN 60923 on 2005-10-01.
This European Standard supersedes EN 60923:1996 + A1:2001.
The purpose of publishing this new edition of EN 60923 was to remove EMC related requirements
which are deemed to be of a regional nature. At the same time, references to quoted standards were
updated.
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) 2006-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-10-01
This standard is to be read in conjunction with EN 61347-2-9, Lamp controlgear – Part 2-9: Particular
requirements for ballasts for discharge lamps (excluding fluorescent lamps) together with EN 61347-1,
Lamp controlgear – Part 1: General and safety requirements.
NOTE In this standard, the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type
– Explanatory matter: in smaller roman type.
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 60923:2005 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60921 NOTE Harmonized as EN 60921:2004 (not modified).
IEC 61000-3-2 NOTE Harmonized as EN 61000-3-2:2000 (modified).

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
