Abstract

IEC 61000-4-3: 2020 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated, radio-frequency electromagnetic fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against RF electromagnetic fields from RF sources not in close proximity to the EUT. The test environment is specified in Clause 6. NOTE 1As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. NOTE 2 Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39. Particular considerations are devoted to the protection against radio-frequency emissions from digital radiotelephones and other RF emitting devices. NOTE 3 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined in this basic document have the primary objective of establishing an adequate reproducibility of testing configuration and repeatability of test results at various test facilities. This document is an independent test method. It is not possible to use other test methods as substitutes for claiming compliance with this document. This fourth edition cancels and replaces the third edition published in 2006, Amendment 1:2007 and Amendment 2:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
  1. testing using multiple test signals has been described;
  2. additional information on EUT and cable layout has been added;
  3. the upper frequency limitation has been removed to take account of new services;
  4. the characterization of the field as well as the checking of power amplifier linearity of the immunity chain are specified.
