Title
Electromagnetic compatibility (EMC) Part 4-21: Testing and measurement techniques Reverberation chamber test methods

Scope:
This part of IEC 61000 considers immunity and wanted and unwanted emissions tests for electric and/or electronic equipment and screening effectiveness tests. Only radiated phenomena are considered. It establishes the required test procedures for using reverberation chambers for performing radiated immunity, radiated emissions and screening effectiveness testing.
The object of this part is to establish a common reference for using reverberation chambers to evaluate the performance of electric and electronic equipment when subjected to radio-frequency electromagnetic fields and for determining the levels of radio-frequency radiation emitted from electric and electronic equipment.
NOTE Test methods are defined in this part for measuring the effect of electromagnetic radiation on equipment and the electromagnetic emissions from equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined are structured for the primary objective of establishing adequate repeatability of results at various test facilities for qualitative analysis of effects.
This part of IEC 61000 does not intend to specify the tests to be applied to particular apparatus or system(s). Its main aim is to give a general basic reference to all concerned product committees of the IEC. The product committees are to select emission limits and test methods in consultation with CISPR. The product committees remain responsible for the appropriate choice of the immunity tests and the immunity test limits to be applied to their equipment. This part of IEC 61000 describes other test methods than IEC 61000-4-3 and CISPR 16-2. The other methods may be used in consultation with CISPR and TC 77, if so specified by product committees.
