This European Standard was approved by CENELEC on 2008-09-01. 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, 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, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of the International Standard IEC 62471:2006, prepared by IEC TC 76 "Optical radiation
safety and laser equipment", together with the common modifications prepared by the Technical
Committee CENELEC TC 76, Optical radiation safety and laser equipment, was submitted to the
formal vote and was approved by CENELEC as EN 62471 on 2008-09-01.
This European Standard partially supersedes EN 60825-1:1994 + corrigendum February 1995 +
A1:2002 + A2:2001 + A2:2001/corrigendum April 2004.
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) 2009-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-09-01
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 62471:2006/CIE S 009:2002 was approved by CENELEC
as a European Standard with agreed common modifications as given below.

The International Standard IEC 62471:2006 was prepared as CIE S 009:2002 by the International
Commission on Illumination. It was submitted to the IEC National Committees for voting under the
Fast Track Procedure. It is published as a double logo IEC and CIE standard.

COMMON MODIFICATIONS
4 Exposure limits
Move the contents of the whole Clause 4 into a new informative Annex ZB. Keep the
numbering.
Replace the current Clause 4 with the following:
4 Exposure limits
The original Clause 4 of IEC 62471:2006 contains provisions governing limiting values for
the exposure of persons falling within the area of the health and safety of workers. Within
Europe those limiting values are already covered by the Artificial Optical Radiation Directive
(2006/25/EC). Thus, the limits of the directive have to be applied instead of those fixed in
IEC 62471:2006.
For information the original Clause 4 of IEC 62471:2006 was moved to the informative
Annex ZB under retention of the respective numbering.

4.1 General
