Overview
CISPR 14-1:2020 - Electromagnetic compatibility (EMC) - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission is the 7th edition international standard published by IEC/CISPR. It specifies radio‑frequency emission requirements for appliances, electric tools and similar apparatus powered from AC or DC (including battery) in the frequency range 9 kHz to 400 GHz. The standard covers whole products and certain separate parts (e.g., motors, switching devices) and explicitly includes products with embedded radio functions and equipment using inductive power transfer (IPT). Exclusions include equipment whose RF emission limits are defined in other CISPR standards, equipment solely intended for vehicles/ships/aircraft, equipment for industrial-only environments, and safety‑related electromagnetic effects.
Key topics and technical requirements
- Scope & applicability: Defines categories of covered equipment (household appliances, electric tools, similar apparatus) and exceptions.
- Emission limits: Detailed limits for continuous and discontinuous disturbances across defined frequency bands (e.g., 9 kHz–30 MHz, 30 MHz–1 GHz, 1 GHz–6 GHz), with application rules in Clause 4.
- Test methods & measurement setups: Procedures for conducted and radiated measurements, including required test equipment such as measuring receivers, Artificial Mains Network (AMN), voltage/current probes, artificial hand, absorbing clamp and radiated emission test sites.
- Measurement interpretation: Rules for continuous and discontinuous disturbance analysis, including click analysis methodology, observation times and the upper‑quartile method.
- Operating conditions: Standard operating conditions, mains/DC supply requirements, multifunction equipment clauses (6.5), IPT-specific test requirements and Annex A standard operating conditions and loads for specific equipment types.
- Technical updates in 2020 edition:
- Extension of radiated measurement frequency range above 1 GHz.
- Revised general and new specific test conditions (e.g., robotic equipment).
- Additional IPT requirements.
- Removal of statistical‑based compliance requirements from normative text.
- Updated click analysis procedures.
Practical applications and who uses it
- Product designers and electrical/electronic engineers use CISPR 14-1:2020 to design appliances and tools that meet EMC emission limits early in development.
- EMC test laboratories and compliance officers use the measurement methods and reporting requirements for pre‑compliance and formal certification testing.
- Manufacturers and regulatory bodies use the standard to support market access, demonstrate conformity, and reduce risk of interference with radio services.
- Test planners use Annex A for equipment‑specific operating conditions; engineers use click analysis and IPT guidance for emerging product features.
Related standards
- Emission requirements explicitly formulated in other CISPR standards take precedence where applicable. CISPR 14-1 should be used alongside other IEC/CISPR EMC guidance and the ITU definition of radio transmitters when addressing intentional transmissions and spurious emissions.
Keywords: CISPR 14-1:2020, electromagnetic compatibility, EMC emission, household appliances, electric tools, radiated emission, conducted emission, inductive power transfer, click analysis, AMN, EMC testing.

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
rights. IEC shall not be held responsible for identifying any or all such patent rights.
The International Standard CISPR 14-1 has been prepared by subcommittee CISPR/F:
