The present document contains the common requirements for marine radio communications and radio determination equipment and associated ancillary equipment operating from any combination of internal batteries, DC and single phase AC, in respect of ElectroMagnetic Compatibility (EMC). The provisions of the present document apply to marine radio equipment not covered in the scope of the Council Directive on marine equipment (the "Marine Equipment Directive" 2014/90/EU [i.4]). Product dependent arrangements necessary to perform the EMC tests on dedicated types of marine radio communications and radio determination equipment, and the assessment of test results, are detailed in the appropriate product related parts of the present document. The present document, together with the product related part, specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for marine radio equipment and associated ancillary equipment. In case of differences (for instance concerning special conditions, definitions, abbreviation) between the present document and the relevant product related part of the present document, the product related part takes precedence. For the further content of the present document, the expression "radio equipment" is taken to mean marine radio communications or radio determination equipment, in each individual case. Technical specifications related to the antenna port of radio equipment and emissions from the enclosure port of radio equipment and combinations of radio and associated ancillary equipment are not included in the present document. Such technical specifications are normally found in the relevant product standards for the effective use of the radio spectrum. The environment classification used in the present document is maritime, as defined in EN IEC 60945 [i.3]. Marine radio communications equipment meeting the EMC requirements set out in EN IEC 61000-6-3 [i.1] and EN 61000-6-1 [i.2] is deemed to meet also the EMC requirements for the maritime environment described in EN IEC 60945 [i.3]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be used in the maritime environment. The levels, however, do not cover extreme cases which may occur in any location but with low probability of occurrence.

IEC 61000-2-9: 2025 defines the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. There are two cases of nuclear detonations:
- high-altitude nuclear explosions;
- low-altitude nuclear explosions.
For civil systems, the most important case is the high-altitude nuclear explosion. In this case, the other effects of the nuclear explosion such as blast, ground shock, thermal and nuclear ionizing radiation are not present at the ground level. However, the electromagnetic pulse associated with the explosion can cause disruption of, and damage to, communications, electronic systems, electric power systems and other portions of the commercial critical infrastructures, thereby upsetting the stability of modern society. The object of this document is to establish a common reference for the HEMP environment in order to select realistic stresses to apply to victim equipment for evaluating their performance and in order to develop protection methods to minimize the impacts of the HEMP. This second edition cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) updating the document to provide new information on the variation of the early-time HEMP on the earth's surface and to provide new information on the late-time HEMP;
b) adding a new informative Annex A which provides details concerning the development of the early- and late-time standard waveforms in the main body, an explanation of the advantages and disadvantages for the use of the double exponential waveform, and an explanation of the far field region for the early-time HEMP.
IEC 61000-2-9: 2025 has the status of a basic EMC publication in accordance with IEC Guide 107.

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 document applies to electrical equipment using signals in the frequency range 3 kHz to 95 kHz to transmit or receive information on low voltage electrical systems, for electricity suppliers and distributors.
Mains communicating equipment (MCE) may fall into one of the two following categories:
- MCE implementing transmission or reception of information on LV distribution networks or installations of network users connected to the public electricity distribution network as the sole function. Immunity requirements for such equipment are entirely covered by this document;
- MCE being equipment covered by the scope of other standards, integrating mains communication as one of their functions. In this case, only the immunity requirements for the mains communication function of such equipment are covered by the scope of this document. Immunity requirements for all other available functions of this equipment are covered by the relevant product standard or generic standard.
The object of this document is to contribute to ensuring EMC in general. It specifies essential immunity requirements and test methods, including those tests which are to be performed during type-testing of MCE, for electromagnetic interference (EMI) generated on LV installations.
It defines the methods and requirements for testing immunity of MCE on meeting the essential requirements of the EMCD. Test requirements are specified for each port considered.
Furthermore, it provides guidelines for the assessment of the performance of the communication function of an MCE. Normative specifications are under consideration.
This document gives immunity requirements which are applicable to MCE used by electricity suppliers and distributors (e.g. DSOs) for purposes like energy management and network monitoring and automation. The levels do not however cover extreme cases which could occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances could exceed the levels specified in this document, e.g. where a hand-held transmitter is used in proximity of an apparatus. In these instances special mitigation measures might have to be employed.
It does not specify immunity of MCE to signals from other MCE operating in the same nominal frequency band or immunity to signals originating from power line carrier systems operating on high or medium-voltage networks.
Safety considerations are not included in this document.
