IEC 61000-4-2: 2025 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges from operators directly and from personnel to adjacent objects. It additionally specifies ranges of test levels which relate to different environmental, and installation conditions and establishes test procedures. The objective of this document is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. In addition, it includes electrostatic discharges which can occur from personnel to objects near the equipment. This document specifies:
- ideal waveform of the discharge current;
- range of test levels;
- test equipment;
- test setup;
- test procedure;
- calibration procedure;
- measurement uncertainty.
This document gives specifications for tests performed in laboratories and guidance to post-installation tests. This document is not intended to specify the tests to be applied to particular apparatus or systems. The main aim is to give a general basic reference to all concerned product committees. The product committees remain responsible for the appropriate choice of the tests and the severity level to be applied to their equipment. This document excludes tests intended to evaluate the ESD sensitivity of devices during handling and packaging. It is not intended for use in characterizing the performance of ESD protection circuit IEC Guide 107.
This document forms Part 4-2 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision.

IEC 61000-4-41:2024 relates to broadband radiated disturbances generated by, for example, communication devices or services, transmitters or industrial electromagnetic sources or any other devices capable of generating such a signal.
The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to broadband radiated electromagnetic fields.
This document specifies testing in the frequency ranges above 80 MHz, limited only by the capabilities of commercially available test instrumentation.
It forms Part 4-41 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107.

The contents of the Interpretation sheet 1 (2025-04), applying to the English version only, have been included in this copy.

IEC 61000-2-4:2024 is available as IEC 61000-2-4:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61000-2-4:2024 is related to conducted disturbances in the frequency range from 0 kHz to 150 kHz. It gives compatibility levels in differential mode (L-L and L-N) for industrial locations, with a nominal voltage up to 35 kV and a nominal frequency of 50 Hz or 60 Hz.
NOTE 1 Industrial locations are defined in 3.1.8.
Power distribution systems on ships, aircraft, offshore platforms and railways are not included.
NOTE 2 See also Annex E. The compatibility levels specified in this document apply at the in-plant point of coupling (IPC). The level of the low-frequency disturbances at the terminals of equipment receiving its supply from the IPC is generally assumed to be similar to the disturbance level at the IPC itself. However, in some situations this is not the case, particularly when a long feeder is dedicated to the supply of a particular load, or when a disturbance is generated or amplified within the installation of which the equipment forms a part.
Compatibility levels are specified for the types of low-frequency electromagnetic disturbances expected at any in-plant point of coupling (IPC) within industrial locations, for guidance in the definition of:
a) limits for disturbance emissions in industrial power distribution systems (including the planning levels defined in 3.1.5);
NOTE 3 A very wide range of conditions is possible in the electromagnetic environments of industrial networks. These are approximated in this document by the three classes described in Clause 4. However, it is the responsibility of the operator of such a network to take account of the particular electromagnetic and economic conditions, including equipment characteristics, in setting the above-mentioned limits.
b) immunity levels for the equipment within these systems.
The disturbance phenomena considered are:
- voltage deviations;
- voltage dips and short interruptions;
- voltage imbalance;
- power-frequency variations;
- harmonics up to order 40;
- interharmonics up to the 40th harmonic;
- voltage components above the 40th harmonic up to 150 kHz;
- DC component;
- transient overvoltages.
The compatibility levels are given for different classes of environment determined by the characteristics of the supply network and loads.
NOTE 4 Compatibility levels at the point of common coupling (PCC) on public networks are specified in IEC 61000‑2‑2 for low-voltage networks and IEC 61000‑2‑12 for medium-voltage networks. IEC TR 61000‑3‑6 and IEC TR 61000‑3‑7 describe the approach of power distribution system operators to the limitation of emissions from installations and large loads.
This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of new classes 2a, 2b and 2L (former class 2);
b) modification of existing compatibility levels for class 3;
c) addition of compatibility levels in the frequency range 2 kHz to 150 kHz;
d) addition of compatibility levels using a new quantity: partial weighted harmonic distortion (PWHD).

This CENELEC Guide establishes useful guidelines for the preparation and use of standards in the field of electromagnetic compatibility (EMC) in general, and in particular for the implementation of the EMC Directive and the Radio Equipment Directive (RED). This Guide is intended to be used by Technical Committees.
The purpose of this guide is to give advice on:
-  the preparation of dedicated Product and Product Family Standards;
-  the application of EMC Standards.
Certification aspects are not covered by this Guide.
NOTE Certification is the action by a third party demonstrating that adequate confidence is provided that a duly identified product, process or service is in conformity with a standard or with other normative documents.

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.

This document specifies statistical considerations for the evaluation of unwanted radio frequency emissions of mass-produced products.
NOTE 1   It is based on CISPR TR 16-4-3.
The reasons for such statistical considerations are:
a)   that the abatement of interference aims that the majority of the products to be approved shall not cause interference;
b)   that the CISPR limits should be suitable for the purpose of type approval of mass-produced products as well as approval of single-produced products;
c)   that to ensure compliance of mass-produced products with the CISPR limits, statistical techniques have to be applied;
d)   that it is important for international trade that the limits shall be interpreted in the same way in every country.
Therefore, this document specifies requirements and provides guidance based on statistical techniques. EMC compliance of mass-produced products with the requirements of this document are based on the application of statistical techniques that reassure the consumer, with an 80 % degree of confidence, that 80 % of the products of a type being investigated comply with the limits for unintended radio frequency emission.
This document does not define limits or measuring methods. It can be used only after measurements of unwanted radio frequency emissions have been performed according to the applicable standard for the unwanted radio frequency emissions.
NOTE 2   Clause 4 gives some general requirements on the interpretation of CISPR radio disturbance limits and specifies different methods, which can be used alternatively. Clause 5 gives some specific requirements for certain product groups.
NOTE 3    This document does not give a calculation method about the manufacturer’s risk, whether a type of products will be accepted during a second statistical evaluation. More information on the acceptance probability for a repeated measurement is given in CISPR TR 16 4 3, Edition 2.1, Annex D.

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.

   
1. provide information on the testing of large EUTs (including cables);

   
2. apply the work on measurement uncertainties by adapting the work completed in CISPR and TC 77 (for emissions and immunity);

   
3. update the validation procedure for the test volume regarding field uniformity and TEM mode verification;

   
4. provide information concerning two-port and four-port TEM waveguides;

   
5. add a new informative annex (Annex I) dealing with transient TEM waveguide characterization; and

   
6. add information dealing with dielectric test stands for EUTs.

This document contains limits and procedures for the measurement of radio disturbances in the
frequency range of 150 kHz to 5 925 MHz. This document applies to vehicles, boats, internal
combustion engines, trailers, devices and any electronic/electrical component intended for use
in vehicles, boats, trailers and devices. Refer to International Telecommunications Union (ITU)
publications for details of frequency allocations. The limits are intended to provide protection
for on-board receivers installed (per the manufacturer’s guidelines) in a vehicle from
disturbances produced by components/modules in the same vehicle.
The receiver types to be protected are, for example, broadcast receivers (sound and television),
land mobile radio, radio telephone, amateur, citizens' radio, Satellite Navigation (GPS etc.), WiFi, V2X, and Bluetooth.
This document does not include protection of electronic control systems from radio frequency
(RF) emissions or from transient or pulse-type voltage fluctuations. These subjects are included
in ISO publications.
The limits in this document are recommended and subject to modification as agreed between
the customer (e.g. vehicle manufacturer) and the supplier (e.g. component manufacturer). This
document is also intended to be applied by vehicle manufacturers and suppliers which are to
be added and connected to the vehicle harness or to an on-board power connector after delivery
of the vehicle.
This document defines test methods for use by vehicle manufacturers and suppliers, to assist
in the design of vehicles and components and ensure controlled levels of on-board radio
frequency emissions.
The emission requirements in this document are not intended to be applicable to the intentional
transmissions from a radio transmitter as defined by the ITU including their spurious emissions.
NOTE 1 This exclusion is limited to those intended transmitter emissions, which leave the EUT as radiated
emissions and are coupled onto the wire line in the measurement setup. For conducted transmissions on frequencies
intentionally produced by the radio part of an EUT, this exclusion does not apply.
NOTE 2 It is usual for customers and suppliers to use radio regulation standards to manage the effect of spurious
emissions from a radio transmitter unless limits of spurious emission are agreed in the test plan.

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 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. 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:
- testing using multiple test signals has been described;
- additional information on EUT and cable layout has been added;
- the upper frequency limitation has been removed to take account of new services;
- the characterization of the field as well as the checking of power amplifier linearity of the immunity chain are specified.

\r\nIEC 61000-6-4:2018 for emission requirements applies to electrical and electronic equipment intended for use within the environment existing at industrial (see 3.1.12) locations. This document does not apply to equipment that fall within the scope of IEC 61000-6-3. The environments encompassed by this document cover both indoor and outdoor locations. Emission requirements in the frequency range 9 kHz to 400 GHz are covered in this document and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. No measurement needs to be performed at frequencies where no requirement is specified. These requirements are considered essential to provide an adequate level of protection to radio services. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the environments included within this document. Requirements are specified for each port considered. This generic EMC emission standard is to be used where no applicable product or product-family EMC emission standard is available. This third edition cancels and replaces the second edition published in 2006 and Amendment 1:2010 This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
\r\na) possible future requirements on DC ports;
\r\nb) possible future radiated polarity specific emission limits within a FAR;
\r\nc) the definition of which average detector is used for emission measurements at frequencies above 1GHz and that results using a peak detector are acceptable for all measurements;
\r\nd) the definition of different EUT test arrangements.
\r\nKeywords: emission standard for industrial environments

This part of CISPR 16 specifies the methods of measurement of radiated disturbance
phenomena in the frequency range of 9 kHz to 18 GHz. The aspects of measurement
uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2.
NOTE In accordance with IEC Guide 107 [13]1, CISPR 16-2-3 is a basic EMC publication for use by product
committees of the IEC. As stated in Guide 107, product committees are responsible for determining the
applicability of the EMC standard. CISPR and its subcommittees are prepared to co-operate with product
committees in the evaluation of the value of particular EMC tests for specific products.

This standard applies to the emission (radiated and conducted) of radiofrequency disturbances from: - lighting equipment (3.3.16); - the lighting part of multi-function equipment where this lighting part is a primary function;.- UV and IR radiation equipment for residential and non-industrial applications; - advertising signs; - decorative lighting; - emergency signs. Excluded from the scope of this document are: - components or modules intended to be built into lighting equipment and which are not user-replaceable; - lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation); - lighting equipment for aircraft and airfield facilities (runways, service facilities, platforms); - video signs; - installations; - equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a builtin lighting function. The frequency range covered is 9 kHz to 400 GHz. No measurements need to be performed at frequencies where no limits are specified in this document. Multi-function equipment which is subjected simultaneously to different clauses of this document and/or other standards need to meet the provisions of each clause/standard with the relevant functions in operation. For equipment outside the scope of this document and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this document, provided that the lighting function was operative during the assessment in accordance with the applicable standard.

This part of IEC 61000 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. Equipment which does not comply with the limits of this part of IEC 61000 when tested with the reference impedance Zref of 6.4, and which therefore cannot be declared compliant with this part, may be retested or evaluated to show conformity with IEC 61000-3-11. Part 3-11 is applicable to equipment with rated input current ≤ 75 A per phase and subject to conditional connection. The tests according to this part are type tests. Particular test conditions are given in Annex A and the test circuit is shown in Figure 1.

This standard is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public low voltage a.c. distribution systems having a nominal voltage up to 420 V, single-phase or 690 V, three-phase and a nominal frequency of 50 Hz or 60 Hz.

This part of IEC 61000 focuses on the immunity requirements and test methods for electrical
and electronic equipment, under operational conditions, with regard to:
a) repetitive slow damped oscillatory waves occurring mainly in power, control and signal
cables installed in high voltage and medium voltage (HV/MV) substations;
b) repetitive fast damped oscillatory waves occurring mainly in power, control and signal
cables installed in gas insulated substations (GIS) and in some cases also air insulated
substations (AIS) or in any installation due to high-altitude electromagnetic pulse (HEMP)
phenomena.
The object of this document is to establish a common and reproducible reference for
evaluating the immunity of electrical and electronic equipment when subjected to damped
oscillatory waves on supply, signal, control and earth ports. 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.
NOTE 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 is applied or not, and if applied, they are responsible for determining the appropriate test levels and
performance criteria. 1
