scope:

This International Standard defines a measurement and calculation method of the total input power for control gear - lamp circuits when operating with their associated fluorescent lamp(s). The calculation method for the efficiency of the lamp control gear is also defined. This International Standard applies to electrical control gear - lamp circuits comprised solely, the control gear and the lamp(s) for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz. NOTE: Requirements for testing individual control gear during production are not included. It specifies the measurement method for the total input power and the calculation method of the control gear efficiency for all control gear used for domestic and normal commercial purposes operating with the following fluorescent lamps: - linear fluorescent lamps; - single ended (compact) fluorescent lamps; - other general purpose fluorescent lamps. This International Standard does not apply to: - control gear which form an integral part of the lamp; - controllable wire-wound magnetic control gear; - luminaires, which rely on additional optical performance aspects.
