Electromagnetic compatibility (EMC) - Part 4-3: Testing and measurement techniques - Radiated, radiofrequency, electromagnetic field immunity test

This part of IEC 61000 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 1 As 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.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 4-3: Testing and measurement techniques –
Radiated, radio-frequency electromagnetic field immunity test
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

...
