IEC 62442-1:2018 pdf download.Energy performance of lamp controlgear – Part 1: Controlgear for fluorescent lamps
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: – linear fluorescent lamps; – single-ended (compact) fluorescent lamps; – other general purpose fluorescent lamps. This document 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 nominal value suitable approximate quantity value used to designate or identify a component, device or equipment 3.2 limiting value greatest or smallest admissible value of one of the quantities 3.3 rated value quantity value for specified operating conditions of a component, device or equipment Note 1 to entry: The value and conditions are specified in the relevant standard or assigned by the manufacturer or responsible vendor. Note 2 to entry: For the different kinds of operation, rated electrical values are given on the lamp data sheets as: − rated electrical values under “electrical characteristics”, if the lamp is defined for 50 Hz/60 Hz operation only, − rated electrical values under “electrical characteristics”, if the lamp is defined for high frequency (≥ 20 kHz) operation only, − rated electrical values and typical electrical values, if the lamp is defined simultaneously for 50 Hz/60 Hz operation and high frequency operation • for 50 Hz/60 Hz operation: rated electrical values under “electrical characteristics”, and • for high frequency operation: rated electrical values under “typical lamp characteristics”. 3.4 controlgear one or more components between the supply and one or more lamps which may serve to transform the supply voltage, limit the current of the lamp(s) to the required value, provide starting voltage and preheating current, prevent cold starting, correct power factor or reduce radio interference 3.5 electromagnetic controlgear magnetic controlgear controlgear which, by means of inductance, or a combination of inductance and capacitance.3.7 fluorescent lamp discharge lamp of the low pressure mercury type, in which most of the light is emitted by one or several layers of phosphors excited by the ultra-violet radiation from the discharge 3.8 controlgear-lamp circuit electrical circuit, or part thereof, normally built in a luminaire, consisting of the controlgear and lamp(s) 3.9 reference ballast special ballast, either inductive for lamps for operation on AC mains frequencies, or resistive for lamps for operation on high frequency Note 1 to entry: It is designed for the purpose of providing comparison standards for use in testing ballasts, for the selection of reference lamps and for testing regular production lamps under standardized conditions. It is essentially characterized by the fact that, at its rated frequency, it has a stable voltage/current ratio which is relatively uninfluenced by variations in current, temperature and magnetic surroundings, as outlined in IEC 60929 and IEC 60921 .
