IEC 62718:2013

Railway applications - Rolling stock - DC supplied electronic ballasts for lighting fluorescent lamps

IEC 62718:2013 specifies the performance and constructional requirements, and associated tests, for d.c. supplied electronic ballasts used to supply fluorescent lamps for lighting on railway rolling stock. Its requirements replace those of IEC 61347 for all railway rolling stock applications and specify and complete those of IEC 61347 for the specific needs of railway rolling stock applications. The contents of the corrigendum of February 2016 have been included in this copy.

Applications ferroviaires - Matériel roulant - Ballasts électroniques à courant continu pour lampes fluorescentes d'éclairage

La CEI 62718:2013 spécifie les exigences relatives à la construction et aux performances, et les essais correspondants, pour les ballasts électroniques alimentés en courant continu utilisés pour alimenter les lampes fluorescentes pour l'éclairage du matériel roulant ferroviaire. Ses exigences remplacent celles de la CEI 61347 pour toutes les applications sur le matériel roulant ferroviaire; elles précisent et complètent celles de la CEI 61347 pour les besoins spécifiques des applications ferroviaires. Le contenu du corrigendum de février 2016 a été pris en considération dans cet exemplaire.
