Overview

EN IEC 63474:2023 (adopted by CLC/CENELEC from IEC 63474:2023) defines standardized methods to measure and report networked standby power consumption for electrical and electronic household and office edge equipment. The standard targets devices with wired or wireless network ports that can be remotely reactivated (remotely initiated triggers). It complements existing standby measurement standards (e.g., EN 50564 / IEC 62301) by focusing specifically on networked standby behaviour, power management testing, and verification of wireless connection deactivation. The standard does not apply to interconnecting equipment.

Key topics and technical requirements

• Measurement scope: Procedures for measuring electrical power consumption in networked standby for edge equipment and how to report results.
• Power management testing: Methods to exercise and measure device power management and reactivation behaviour, including reactivation triggers.
• Wireless connection management: Procedures to test whether wireless network connections can be deactivated and to verify active/inactive wireless states.
• Measurement conditions and instrumentation: Requirements for test room, power supply, power measuring instruments, measurement uncertainty, and common test conditions.
• Network configuration: Guidance on preparing and configuring network ports (wired and wireless) for tests, and test sequences for connected vs disconnected ports.
• Reporting: Required test report content, including laboratory details, product information, test parameters, network configurations, and measured data.
• Annexes and examples: Normative and informative annexes cover connection-type test conditions, equipment classification, network technology examples, user information, and a sample test report template.

Applications and who uses it

• Manufacturers of household and office electronics (smart appliances, smart speakers, printers, IoT edge devices) use the standard to characterize and optimize networked standby power.
• Test laboratories and compliance bodies adopt the measurement procedures for consistent, repeatable testing and certification.
• Product designers and energy engineers use results to improve power management, reduce standby energy use, and comply with energy labeling/regulatory requirements.
• Regulators and procurement teams reference standardized metrics when setting limits or evaluating products for energy efficiency programs.

Related standards

• EN 50564 / IEC 62301 - Measurement of low power/standby (complements EN IEC 63474 for non-networked standby).
• IEC 63474:2023 - International text adopted as EN IEC 63474:2023.

EN IEC 63474:2023 is essential for anyone needing accurate, repeatable measurement of networked standby power in edge equipment and for improving the energy profile of connected consumer and office devices.

CONSUMPTION OF EDGE EQUIPMENT
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
