IEC 63474:2023 PDF

Overview

IEC 63474:2023 - Electrical and electronic household and office equipment – Measurement of networked standby power consumption of edge equipment is an International Standard developed by the International Electrotechnical Commission (IEC). This document specifies standardized methods for measuring and reporting the electrical power consumption of edge equipment in networked standby mode. The goal is to provide a consistent framework for manufacturers, laboratories, and regulatory bodies to assess, compare, and communicate the energy usage of household and office devices that remain connected to a network in standby condition.

IEC 63474:2023 focuses on "edge equipment," including consumer electronics, information technology products, and similar appliances that can connect to a network but do not primarily act as network traffic intermediaries. It also provides guidance on verifying power management features and the ability to deactivate wireless network connections. Networked standby energy use is an increasingly important consideration for power efficiency, energy labeling, and eco-design initiatives worldwide.

Key Topics

• Measurement Procedures: IEC 63474:2023 details the precise methods for measuring power consumption when edge equipment is in networked standby, ensuring repeatability and comparability across products and laboratories.
• Networked Standby Definition: The standard defines networked standby as a condition where equipment can resume functions upon receiving a trigger from a network connection.
• Testing Wireless and Wired Ports: Procedures are included for evaluating both wired and wireless network ports, covering activation, deactivation, and configuration for accurate measurement.
• Power Management Verification: The document specifies how to test and report on equipment's automated power management functions, including the transition to networked standby and back to active mode.
• Information Disclosure: Manufacturers are guided on the type of information to provide for testing, such as power management time periods, network protocols, and procedures for connection management.
• Exclusions: The standard does not cover interconnecting equipment (such as network switches or routers), which is addressed by other standards like EN 303 423.

Applications

Implementing IEC 63474:2023 brings practical value in several key areas:

• Eco-design Compliance: Regulatory authorities and manufacturers can use this standard to meet international energy efficiency requirements for household and office equipment.
• Product Development: Designers and engineers can optimize devices to minimize networked standby consumption, improving energy ratings and competitive advantage.
• Energy Labeling: Certification and labeling schemes can reliably assess and compare energy consumption in networked standby mode using standardized methods.
• Testing and Certification: Accredited laboratories use these methods for conformity assessment, ensuring reported results are robust and globally accepted.
• User Information: Clear disclosure requirements help inform end-users on how products consume power in networked standby and how functions such as wireless deactivation impact energy use.

Related Standards

• EN 50564: Covers the measurement of low power consumption, including standby and off modes, for household and office equipment. Essential for measuring non-networked standby modes.
• EN 303 423: Focuses on the measurement of power consumption in networked standby for interconnecting equipment, such as network switches, distinct from edge equipment.
• IEC 60050: International Electrotechnical Vocabulary, offering definitions for key network and power management terms.
• Other IEC/ISO Directives: Ensure harmonized terminology and procedures across international standards in electrotechnical fields.

Summary

IEC 63474:2023 provides a unified methodology for measuring the networked standby power consumption of edge devices, enabling compliance, transparency, and optimization in line with modern energy efficiency standards. By adopting this international standard, stakeholders can ensure environmentally responsible product operation, clarity in reporting, and support for global regulatory frameworks concerning connected household and office equipment.
