IEC 62493:2009

Assessment of lighting equipment related to human exposure to electromagnetic fields

IEC 62493:2009 applies to the assessment of lighting equipment related to human exposure to electromagnetic fields. The assessment consists of the induced current density for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for frequencies from 100 kHz to 300 MHz around lighting equipment. This standard does not apply to built-in components for luminaires such as electronic control gear.

Évaluation d'un équipement d'éclairage relativement à l'exposition humaine aux champs électromagnétiques

La CEI 62493:2009 traite de l'évaluation d'un équipement d'éclairage relativement à l'exposition humaine aux champs électromagnétiques. L'évaluation comprend la densité du courant induit pour les fréquences comprises entre 20 kHz et 10 MHz et le débit d'absorption spécifique (SAR) pour les fréquences comprises entre 100 kHz et 300 MHz autour de l'équipement d'éclairage. La présente norme ne s'applique pas aux composants intégrés dans des luminaires, tels que les appareillages électroniques.
