IEC 61547-1 describes an objective light flickermeter, which can be applied for thefollowing purposes:- measuring the intrinsic performance of all lighting equipment without the application ofvoltage fluctuations in terms of illuminance flicker; during this measurement, the lightingequipment is supplied with a stable mains;- testing the immunity performance of lighting equipment against (unintentional) voltagefluctuation disturbance on the AC mains in terms of illuminance flicker; during this test aset of defined voltage fluctuations are applied to the AC mains and the immunity of thelighting equipment to the disturbance is determined.Apart from the above two purposes, the immunity performance of lighting equipment can alsobe tested against intentional voltage fluctuation on the AC mains arising for example frommains signalling. This is however not described in further detail in this document.NOTE 1 IEC 61000-4-13:2015 [24] provides guidance regarding test levels and frequencies for mains signalling.The object of this document is to establish a common and objective reference for evaluatingthe performance of lighting equipment in terms of illuminance flicker. Temporal changes in thecolour of light (chromatic flicker) are not considered in this test.This method can be applied to lighting equipment which is within the scope of IEC technicalcommittee 34, such as lamps and luminaires, intended for connection to a low voltageelectricity supply. Independent auxiliaries such as drivers can also be tested by application ofa representative light source to that auxiliary.The objective light flickermeter and voltage fluctuation immunity method described in thisdocument are based on the IEC 61000-3-3 standard for voltage fluctuation limits and theflickermeter standard IEC 61000-4-15.The objective light flickermeter described in this document can be applied to objectivelyassess flicker of lighting equipment that is powered from any type of source, AC mains, DCmains, battery fed or fed through an external light level regulator. The specific voltagefluctuation immunity test method described in this document applies to lighting equipmentrated for 120 V AC and 230 V AC, 50 Hz and 60 Hz.
