AS/NZS 61000.4.15:2012

This part of IEC 61000 gives a functional and design specification for flicker measuringapparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to beconstructed. A method is given for the evaluation of flicker severity on the basis of the output of flickermeters complying with this standard.The flickermeter specifications in this part of IEC 61000 relate only to measurements of 120 Vand 230 V, 50 Hz and 60 Hz inputs. Characteristics of some incandescent lamps for other voltages are sufficiently similar to the values in Table 1 and Table 2, that the use of acorrection factor can be applied for those other voltages. Some of these correction factors areprovided in the Annex B. Detailed specifications for voltages and frequencies other than thosegiven above, remain under consideration.The object of this part of IEC 61000 is to provide basic information for the design and theinstrumentation of an analogue or digital flicker measuring apparatus. It does not givetolerance limit values of flicker severity.
