Preface:

This is the second edition of CAN/CSA-IEC 61000-4-15, Electromagnetic compatibility (EMC) - Part 4-15: Testing and measurement techniques - Flickermeter - Functional and design specifications, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 61000-4-15 (second edition, 2010-08). It supersedes the previous edition, published in 2003 as CAN/CSA-CEI/IEC 61000-4-15 (adopted IEC 61000-4-15:1997+A1:2003).

This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Low Frequency EMC, under the jurisdiction of the CSA Technical Committee on Electromagnetic Compatibility and the CSA Strategic Steering Committee on Power Engineering and Electromagnetic Compatibility, and has been formally approved by the Technical Committee. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.

Scope and object:

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.
