1 Scope
This part of IEC 62442 defines a measurement and calculation method of the total input power for controlgear ‒ lamp circuits when operating with their associated fluorescent lamp(s). The calculation method for the efficiency of the lamp controlgear is also defined. This International Standard applies to electrical controlgear lamp circuits consisting only of the controlgear and the lamp(s). It is intended for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
NOTE Requirements for testing individual controlgear during production are not included.
It specifies the measurement method for the total input power and the calculation method of the controlgear efficiency for all controlgear 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:
-
— controlgear which form an integral part of the lamp;
-
— controllable wire-wound magnetic controlgear;
-
— luminaires, which rely on additional optical performance aspects.
