What is this standard about?
This part of IEC 62442 defines a measurement method of the power losses of electromagnetic controlgear, the total input power and the standby power of electronic controlgear for high intensity discharged lamps (excluding fluorescent lamps). A calculation method of the efficiency of controlgear for high intensity discharged lamp(s) is also defined.
It is assumed that the controlgear are designed 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.
This document applies to electrical controlgear-lamp circuits comprised solely of the controlgear and of the lamp(s).
This document specifies the measurement method for the total input power, the standby power and the calculation method of the lamp controlgear efficiency for all controlgear sold for domestic and normal commercial purposes operating with high intensity discharge lamps.
This document does not apply to:
– controlgear which form an integral part of lamps;
– controlgear circuits with capacitors connected in series;
– controllable electromagnetic controlgear.
