BS EN IEC 62442-1:2022 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 document applies to electrical controlgear-lamp circuits consisting only of the controlgear and the lamp(s).
It is intended for use on DC supplies up to 1 000 V and/or AC supplies up to 1 000 V at 50 Hz or 60 Hz.
NOTE: Requirements for testing individual controlgear during production are not included.
This document 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:
– double-capped fluorescent lamps (IEC 60081);
– single-capped fluorescent lamps (IEC 60901);
– other general purpose low-pressure mercury fluorescent lamps.
This document does not apply to:
– controlgear which form an integral part of the lamp;
– controllable wire-wound magnetic controlgear.
