This part of IEC 61000 gives a functional and design specification for flicker measuring
apparatus intended to indicate the correct flicker perception level for all practical voltage
fluctuation waveforms. Information is presented to enable such an instrument to be
constructed. 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 V
and 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 a
correction factor can be applied for those other voltages. Some of these correction factors are
provided in the Annex B. Detailed specifications for voltages and frequencies other than those
given above, remain under consideration.
The object of this part of IEC 61000 is to provide basic information for the design and the
instrumentation of an analogue or digital flicker measuring apparatus. It does not give
tolerance limit values of flicker severity.
