This European Standard gives the measurement method of the total input power for ballast-lamp circuits when operating with their associated fluorescent lamp(s). This standard applies to electrical ballast-lamp circuits comprised solely of the ballast and of the lamp(s).
NOTE Requirements for testing individual ballasts during production are not included.
It specifies the measurement method for the total input power for all ballasts sold for domestic and normal commercial purposes operating with the following fluorescent lamps:
—linear lamps with power equal to or greater than 15 W;
—single ended (compact) lamps with power equal to or greater than 18 W;
—other general purpose lamps.
This standard does not apply to:
—ballasts which form an integral part of the lamp;
—ballast-lamp circuits with capacitors connected in series;
—controllable wire-wound magnetic ballasts;
—luminaires, which rely on additional optical performance aspects.
