This part of IEC 61000 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. NOTE 1 Product committees might decide to use the methods described in this document also for frequencies up to 230 MHz (see Annex B) although the methods and test instrumentation is intended to be used in the frequency range up to 80 MHz. Equipment not having at least one conducting wire and/or cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF fields is excluded from the scope of this publication. NOTE 2 Test methods are specified in this part of IEC 61000 to assess the effect that conducted disturbing signals, induced by electromagnetic radiation, have on the equipment concerned. The simulation and measurement of these conducted disturbances are not adequately exact for the quantitative determination of effects. The test methods specified are structured for the primary objective of establishing adequate repeatability of results at various facilities for quantitative analysis of effects. The object of this standard is to establish a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF 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 a specified phenomenon. NOTE 3 As described in IEC Guide 107, this standard 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.

IEC 61000-4-20:2022 focuses on emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. These types include open structures (for example striplines and electromagnetic pulse simulators) and closed structures (for example TEM cells). These structures can be further classified as one-port, two-port, or multi-port TEM waveguides. The frequency range depends on the specific testing requirements and the specific TEM waveguide type. The object of this document is to describe  
TEM waveguide characteristics, including typical frequency ranges and equipment-under-test (EUT) size limitations;
TEM waveguide validation methods for electromagnetic compatibility (EMC) tests;
the EUT (i.e. EUT cabinet and cabling) definition;
test set-ups, procedures, and requirements for radiated emission measurements in TEM waveguides; and
test set-ups, procedures, and requirements for radiated immunity testing in TEM waveguides.  NOTE Test methods are defined in this document to measure the effects of electromagnetic radiation on equipment and the electromagnetic emissions from the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for the quantitative determination of effects for all end-use installations. The test methods defined are structured for a primary objective of establishing adequate reproducibility of results at various test facilities for qualitative analysis of effects. This document does not intend to specify the tests to be applied to any particular apparatus or system(s). The main intention of this document is to provide a general basic reference for all interested product committees of the IEC. For radiated emission measurements, product committees select emission limits and measurement methods in consultation with CISPR standards. For radiated immunity testing, product committees remain responsible for the appropriate choice of immunity tests and immunity test limits to be applied to equipment within their scope. This document describes test methods that are separate from those of IEC 61000‑4‑3. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
provide information on the testing of large EUTs (including cables);
apply the work on measurement uncertainties by adapting the work completed in CISPR and TC 77 (for emissions and immunity);
update the validation procedure for the test volume regarding field uniformity and TEM mode verification;
provide information concerning two-port and four-port TEM waveguides;
add a new informative annex (Annex I) dealing with transient TEM waveguide characterization; and
add information dealing with dielectric test stands for EUTs.

This part of IEC 61000 defines the immunity test methods and range of recommended basic
test levels for electrical and electronic equipment with rated current up to 16 A per phase at
disturbance frequencies up to and including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz
mains) for harmonics and interharmonics on low voltage power networks.
It does not apply to electrical and electronic equipment connected to 16 2/3 Hz , or to 400 Hz
a.c. networks. Tests for these networks will be covered by future standards.
The object of this standard is to establish a common reference for evaluating the functional
immunity of electrical and electronic equipment when subjected to harmonics and interharmonics
and mains signalling frequencies. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an equipment or system
against a defined phenomenon. 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.
The verification of the reliability of electrical components (for example capacitors, filters, etc.)
is not in the scope of the present standard. Long term thermal effects (greater than 15 min) are
not considered in this standard.
The levels proposed are more adapted for residential, commercial and light industry
environments. For heavy industrial environments the product committees are responsible for
the definition of a class X with the necessary levels. They have also the possibility of defining
more complex waveforms for their own need. Nevertheless, the simple waveforms proposed
have been mainly observed on several networks (flat curve more often for single phase
system) and also on industrial networks (overswing curve more for three phase systems).

IEC 61000-4-5:2014 relates to the immunity requirements, test methods, and range of recommended test levels for equipment with regard to unidirectional surges caused by over-voltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This standard defines a range of: - test levels; - test equipment; - test setups; and - test procedures. The task of the described laboratory test is to find the reaction of the equipment under test (EUT) under specified operational conditions to surge voltages caused by switching and lightning effects. It is not intended to test the capability of the EUT's insulation to withstand high-voltage stress. Direct injections of lightning currents, i.e. direct lightning strikes, are not considered in this standard.

IEC 61000-4-21:2011 considers tests of immunity and intentional or unintentional emissions for electric and/or electronic equipment and tests of screening effectiveness in reverberation chambers. It establishes the required test procedures for performing such tests. Only radiated phenomena are considered. The objective of IEC 61000-4-21:2011 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. IEC 61000-4-21:2011 does not intend to specify the tests to be applied to a particular apparatus or system. Its main aim is to give a general basic reference to all concerned product committees of the IEC. The product committees should 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. Other methods, such as those covered in IEC 61000-4-3, CISPR 16-2-3 and CISPR 16-2-4 may be used. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision and includes the following significant technical changes with respectto the first edition: - In Clause 8, the use and specifications of E-field probes for application to reverberation chambers has been added. - In Annex A, additional guidance and clarifications on the use of reverberation chambers at relatively low frequencies of operation (i.e., close to the lowest usable frequency of a given chamber) are given, and its implications on the estimation of field uncertainty are outlined. - In Annex B, symmetric location of the field probes when the chamber exhibits cylindrical symmetry has been disallowed, as such placement could otherwise yield a false indication of field uniformity and chamber performance at different locations. - Annex C now contains more quantitative guidance on the setting of the maximum permissible stirring speeds that warrant quasi-static conditions of operation for chamber validation and testing. - In Annex D, a requirement for the EUT and equipment not to occupy more than 8 % of the total chamber volume in immunity testing has been added. - Annex E has been extended with further guidance on the value of EUT directivity to be used in the estimation of radiated power and field. - In Annex I, some clarifications on antenna efficiency measurements have been added. - A new Annex K has been added that covers measurement uncertainty in reverberation chambers.

IEC 61000-4-15:2010 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. This second edition cancels and replaces the first edition published in 1997 and its Amendment 1 (2003) and constitutes a technical revision. This new edition, in particular, adds or clarifies the definition of several directly measured parameters, so that diverging interpretations are avoided. It has the status of a basic EMC publication in accordance with IEC Guide 107. NEW! IEC 61000-4-15:2010 is also available as IEC Standards+ 61000-4-15:2010 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61000-4-20:2010 relates to emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. These types include open structures (for example, striplines and electromagnetic pulse simulators) and closed structures (for example, TEM cells). These structures can be further classified as one-, two-, or multi-port TEM waveguides. The frequency range depends on the specific testing requirements and the specific TEM waveguide type. The object of this standard is to describe: - TEM waveguide characteristics, including typical frequency ranges and EUT-size limitations; - TEM waveguide validation methods for EMC tests; - the EUT (i.e. EUT cabinet and cabling) definition; - test set-ups, procedures, and requirements for radiated emission testing in TEM waveguides and - test set-ups, procedures, and requirements for radiated immunity testing in TEM waveguides. IEC 61000-4-20:2010 does not intend to specify the tests to be applied to any particular apparatus or system(s). The main intention of this standard is to provide a general basic reference for all interested product committees of the IEC. For radiated emissions testing, product committees should select emission limits and test methods in consultation with CISPR standards. For radiated immunity testing, product committees remain responsible for the appropriate choice of immunity tests and immunity test limits to be applied to equipment within their scope. This standard describes test methods that are separate from those of IEC 61000-4-3. This second edition cancels and replaces the first edition published in 2003 and its amendment 1 (2006), and constitutes a technical revision. It has the status of a basic EMC publication in accordance with IEC Guide 107. The main changes with respect to the first edition of this standard and its amendment are the following: - consistency of terms (e.g. test, measurement, etc.) has been improved; - clauses covering test considerations, evaluations and the test report have been added; - references to large TEM waveguides have been eliminated; - a new informative annex has been added to deal with calibration of E-field probes.

IEC 61000-4-8:2009 relates to the immunity requirements of equipment, only under operational conditions, to magnetic disturbances at power frequencies 50 Hz and 60 Hz related to: - residential and commercial locations; - industrial installations and power plants; - medium voltage and high voltage sub-stations. The applicability of IEC 61000-4-8:2009 to equipment installed in different locations is determined by the presence of the phenomenon, as specified in Clause 4. This standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation. Other IEC standards dealing with conducted disturbances cover these aspects. The object of IEC 61000-4-8:2009 is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, commercial and industrial applications when subjected to magnetic fields at power frequency (continuous and short duration field). IEC 61000-4-8:2009 defines: - recommended test levels; - test equipment; - test set-up; - test procedure. This second edition cancels and replaces the first edition published in 1993 and its Amendment 1 (2000). It forms a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the scope is extended in order to cover 60 Hz. Characteristics, performance and verification of the test generator and related inductive coils are revised. Modifications are also introduced in the test set-up (GRP) and test procedure. IEC 61000-4-8:2009 has the status of a basic EMC publication in accordance with IEC Guide 107. NEW!

This part of IEC 61000 defines the immunity test methods and range of recommended basic
test levels for electrical and electronic equipment with rated current up to 16 A per phase at
disturbance frequencies up to and including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz
mains) for harmonics and interharmonics on low voltage power networks.
It does not apply to electrical and electronic equipment connected to 16 2/3 Hz , or to 400 Hz
a.c. networks. Tests for these networks will be covered by future standards.
The object of this standard is to establish a common reference for evaluating the functional
immunity of electrical and electronic equipment when subjected to harmonics and interharmonics
and mains signalling frequencies. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an equipment or system
against a defined phenomenon. 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.
The verification of the reliability of electrical components (for example capacitors, filters, etc.)
is not in the scope of the present standard. Long term thermal effects (greater than 15 min) are
not considered in this standard.
The levels proposed are more adapted for residential, commercial and light industry
environments. For heavy industrial environments the product committees are responsible for
the definition of a class X with the necessary levels. They have also the possibility of defining
more complex waveforms for their own need. Nevertheless, the simple waveforms proposed
have been mainly observed on several networks (flat curve more often for single phase
system) and also on industrial networks (overswing curve more for three phase systems).
