(Main)Assessment of lighting equipment related to human exposure to electromagnetic fields
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.
Beurteilung von Beleuchtungseinrichtungen bezüglich der Exposition von Personen gegenüber elektromagnetischen Feldern
Evaluation 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.
Ocenjevanje opreme za razsvetljavo glede izpostavljenosti ljudi elektromagnetnim poljem - Standard za skupino izdelkov (IEC 62493:2009)
Ta mednarodni standard velja za ocenjevanje opreme za razsvetljavo glede izpostavljenosti ljudi elektromagnetnim poljem. Ocenjevanje je sestavljeno iz gostote induciranega toka za frekvence od 20 kHz do 10 MHz in določene stopnje absorpcije (SAR) za frekvence od 100kHz do 300 MHz okoli opreme za razsvetljavo. V področje uporabe tega standarda je vključeno: - vsa oprema za razsvetljavo za splošno razsvetljavo s prvotnim namenom za proizvodnjo in/ali razširitvijo svetlobe, predvidena za namene razsvetlitve, bodisi s priklopom na nizkonapetostno oskrbo z električno energijo ali z delovanjem na baterijo, za notranjo in/ali zunanjo uporabo. Splošna oprema za razsvetljavo pomeni: vso industrijsko, bivalno in javno razsvetljavo; - svetilni del splošne razsvetljave večnamenske opreme, kjer je ena izmed glavnih funkcij osvetljevanje; - neodvisno dodatno opremo, ki se uporablja izključno za opremo za razsvetljavo. Iz področja uporabe tega standarda je izvzeto: - oprema za razsvetljavo za letala in letališča; - oprema za razsvetljavo za cestna vozila (razen razsvetljave, uporabljene za razsvetlitev prostorov za potnike v javnem prevozu); - oprema za razsvetljavo za kmetijstvo; - oprema za razsvetljavo za čolne/plovila, fotokopirne stroje, diaprojektorje; - naprave, za katere so zahteve o elektromagnetnih poljih natančno oblikovane v drugih IEC standardih. Ta standard ne velja za vgradne sestavne dele za svetila, kot je na primer elektronska kontrolna naprava.
