EN 62471:2008

Photobiological safety of lamps and lamp systems

Gives guidance for evaluating the photobiological safety of lamps and lamp systems including luminaires. Specifically it specifies the exposure limits, reference measurement technique and classification scheme for the evaluation and control of photobiological hazards from all electrically powered incoherent broadband sources of optical radiation, including LEDs but excluding lasers, in the wavelength range from 200 nm through 3000 nm. This standard was prepared as Standard CIE S 009:2002 by the International Commission on Illumination.

Photobiologische Sicherheit von Lampen und Lampensystemen

Sécurité photobiologique des lampes et des appareils utilisant des lampes

Fournit un guide pour l'évaluation de la sécurité photobiologique des lampes et des appareils utilisant des lampes. Spécifiquement, elle définit les limites d'exposition, les techniques de mesures de référence et le schéma de classification pour l'évaluation et le contrôle des risques photobiologiques d'une source de radiation optique, alimentée électriquement, incohérente, à spectre large, y compris les LEDs, à l'exclusion des lasers dans un domaine de longueur d'ondes de 200 nm à 3000 nm. Cette norme a été élaborée comme Norme CIE S 009:2002 par la Commission Internationale de l'Eclairage.

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.
