ENERGY PERFORMANCE OF LAMP CONTROLGEAR –

Part 1 : Controlgear for fluorescent lamps –

Method of measurement to determine the total input power

of controlgear circuits and the efficiency of controlgear

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 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
