Lamp controlgear - Part 1: General and safety requirements

This part of IEC 61347 specifies general and safety requirements for lamp controlgear for use
on d.c. supplies up to 250 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
This standard also covers lamp controlgear for lamps which are not yet standardized.
Tests dealt with in this standard are type tests. Requirements for testing individual lamp
controlgear during production are not included.
Requirements for semi-luminaires are given in IEC 60598-1:2014 (see definition 1.2.60).
Particular requirements for controlgears providing safety extra low voltage (from now on
SELV) are given in Annex L.
It can be expected that lamp control gear which comply with this standard will not compromise
safety between 90 % and 110 % of their rated supply voltage in independent use and when
operated in luminaires complying with the safety standard IEC 60598-1 and the relevant part
IEC 60598-2-xx and with lamps complying with the relevant lamp standards. Performance
requirements may require tighter limits.

Geräte für Lampen -- Teil 1: Allgemeine und Sicherheitsanforderungen

Appareillages de lampes -- Partie 1: Exigences générales et exigences de sécurité

NEW! IEC 61347-1:2015 est disponible sous forme de IEC Standards+ 61347-1:2015 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 61347-1:2015 spécifie les exigences générales et les exigences de sécurité pour les appareillages de lampes destinés à être utilisés sur des alimentations à courant continu jusqu'à 250 V et/ou sur des alimentations à courant alternatif jusqu'à 1 000 V à 50 Hz ou 60 Hz. Cette troisième édition annule et remplace la deuxième édition parue en 2007, l'Amendement 1:2010 et l'Amendement 2:2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les exigences de marquage supplémentaires; b) des exigences supplémentaires pour les lignes de fuite et écartements: - pour des tensions de service avec des fréquences de fonctionnement jusqu'à 30 kHz; - pour des tensions de service avec des fréquences de fonctionnement supérieures à 30 kHz; - pour impulsion et la résonance des tensions d'allumage; - pour l'isolation de base, supplémentaire et renforcée; - pour l'isolation entre les circuits; - pour l'appareillage enduit ou en pot; c) modification de la définition d'ELV et de FELV; d) la modification du schéma, montrant les différentes exigences en matière de classification et d'isolation appareillage; e) extension de l'objet; f) la nouvelle Annexe A: essai pour déterminer si une partie conductrice est une partie active qui peut provoquer un choc électrique; g) la nouvelle Annexe M: les lignes de fuite et écartements pour l'appareillage où un plus haut degré de disponibilité (tenue aux chocs de catégorie III) peut être demandée; h) la nouvelle Annexe Q: exemple de calcul Up; i) la nouvelle Annexe P: les distances des lignes de fuite l'écartement et la distance à travers l'isolation (DTI) pour les appareillages de lampes qui sont protégés contre la pollution par l'utilisation d'un revêtement ou d'enrobage; j) la nouvelle Annexe R: concept de lignes de fuite et écartements.

Stikalne naprave za sijalke - 1. del: Splošne in varnostne zahteve

Ta del standarda IEC 61347 določa splošne in varnostne zahteve za stikalne naprave za sijalke za uporabo pri enosmernem napajanju do 250 V in/ali izmeničnem napajanju do 1000 V pri 50 Hz ali 60 Hz. Ta standard obravnava tudi stikalne naprave za sijalke, ki še niso standardizirane. Preskusi, obravnavani v tem standardu, so tipski preskusi. Zahteve za preskušanje posameznih stikalnih naprav za sijalke med proizvodnjo niso vključene. Zahteve za polsvetilke so podane v standardu IEC 60598-1:2014 (glej definicijo 1.2.60). Posebne zahteve za stikalne naprave, ki zagotavljajo varnostno nizko napetost (v nadaljevanju: SELV) so navedene v dodatku L. Pričakuje se lahko, da stikalne naprave za sijalke, ki so v skladu s tem standardom, ne bodo ogrožale varnosti med 90 % do 110 % nazivne napajalne napetosti pri neodvisni rabi in kadar delujejo v svetilkah, ki so v skladu z varnostnim standardom IEC 60598-1 in ustreznim delom standarda IEC 60598-2-xx, ter v sijalkah, ki so v skladu z ustreznimi standardi za sijalke. Za zahteve glede zmogljivosti so potrebne strožje omejitve.
