Overview

EN 61000-3-3:2013/A2:2021 (adopted by CLC/CENELEC) is a European adoption of IEC 61000-3-3 addressing electromagnetic compatibility (EMC) limits for the limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems. It applies to equipment with a rated current ≤ 16 A per phase and not subject to conditional connection. This consolidated copy includes the corrigendum of January 2022 and Amendment A2 (published November 2021), which updates test conditions and measurement procedures for common appliances.

Key Topics and Requirements

• Scope and applicability: Limits and measurement principles for equipment connected to public low-voltage networks where rated current is ≤ 16 A per phase.
• Flicker and voltage fluctuation control: Defines acceptable behavior of equipment so that it does not produce objectionable flicker or unacceptable changes in network voltage.
• Test methods and observation periods: Standardizes measurement intervals and procedures used to evaluate equipment performance on the network.
• Amendment A2 updates (notable items):
  • Microwave ovens: Specified water load, vessel characteristics, initial water temperature, and required power-stage testing and observation timing.
  • Refrigerators and freezers: Continuous operation with door closed, thermostat adjustments, empty cabinet conditions, and exemption for refrigerators with rated power < 200 W.
  • Hairdryers: Observation rules for intermittent operation, settings cycling and inclusion of off periods in measurement.
  • Coffee/tea machines: Warm-up procedure, beverage cycle definitions, and repeatability guidance.
  • Portable fan heaters: Extended evaluation time and defined cycling of heat settings for repeatable measurement.
• Measurement indicators: Use of standard flicker/voltage-change indicators and repeatability requirements (details in the full standard).

Practical Applications

• Manufacturers of household appliances (microwaves, refrigerators, hairdryers, coffee machines, heaters) use this standard to design products that comply with EU EMC limits and avoid causing grid disturbances.
• EMC test laboratories and certification bodies implement the specified test methods to verify compliance and support CE marking or national approvals.
• Utilities and network operators reference the standard to assess and manage equipment-related voltage quality issues in public low-voltage supply systems.
• Compliance engineers and product managers use the standard to set design targets, validate power electronics and control algorithms, and reduce warranty or field issues related to flicker and voltage disturbances.

Related Standards

• IEC 61000 series (Electromagnetic compatibility) - EN 61000-3-3 is part of this broader family covering low-frequency EMC phenomena.
• National and regional EMC regulations and product-specific standards that reference flicker and voltage fluctuation limits.

This standard is essential for ensuring product compliance with flicker and voltage-quality requirements in public low-voltage networks and for harmonizing test procedures across Europe.

AMENDMENT 2
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to IEC 61000-3-3:2013 has been prepared by subcommittee 77A: EMC – Low
frequency phenomena, of IEC technical committee 77:Electromagnetic compatibility.
The text of this Amendment is based on the following documents:
