About This Item


Full Description

1. Scope

This standard covers ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC Publication 81.

It applies to complete ballasts and to their component parts su ch as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in Appendix B.

This standard also specifies ballasts for lamps which are not yet fully standardized.

Ballasts for conventional operation of lamps at mains frequency are covered. A.C. supplied electronic ballasts for high frequency operation are excluded. These are specified in IEC Publicat ion 928.

Capacitors having a capacitance greater than 0.1 ?F are covered by IEC Publication 566. Capacitors having a capacitance less than or equal to 0.1 ?F are specified in IEC Publication 384-14.

Canadian Deviations are included in this Standard. /

1. Domaine d'application

La presente norme traite des ballasts autres que ceux du type a resistance, pour utilisation en courant alternatif jusqu'a 1 000 V, de frequence egale a 50 Hz ou 60 Hz, associes a des lampes tubulaires a fluorescence avec ou sans cathodes prechauffees fonctionnant avec ou sans starter ou dispositif d'amorcage et dont les puissances nominales, les dimensions et les caracteristiques sont indiquees dans la Publication 81 de la CEI.

Elle est applicable aux ballasts complets ainsi qu'a leurs elements constitutifs, tels qu'inductances, transformateurs et condensateurs. Des prescriptions particulieres pour les ballasts a protection thermique se trouvent a l'annexe B.

Cette norme est egalement applicable aux ballasts destines a des lampes dont la normalisation n'est pas encore completement achevee.

Les ballasts concernes sont associes a des lampes alimentees traditionnellement a la frequence du reseau. Les ballasts electroniques alimentes en courant alternatif pour le fonctionnement des lampes a haute frequence sont exclus. Ils font l'objet de la Publication 928 de la CEI.

Les condensateurs de capacite superieure a 0,1 ?F sont traites dans la Publication 566 de la CEI. Les condensateurs de capacite egale ou inferieure a 0,1 ?F sont traites dans la Publication 384-14 de la CEI.

Cette norme comprend des Exigences propres au Canada.
