Overview
EN IEC 63474:2026 sets out standardized methods for measuring the networked standby power consumption of electrical and electronic household and office equipment, specifically for edge equipment. Published by CLC in cooperation with IEC, this standard addresses the growing importance of accurately assessing standby power drawn by devices connected via wired or wireless networks. The standard aims to improve energy efficiency, support environmental goals, and ensure consistent reporting across different product types.
This document supersedes previous editions and extends measurement methodologies to cover both mains-powered and battery-operated products. EN IEC 63474 reflects advances in energy consumption measurement practices and aligns with related standards in the field of electrical energy management.
Key Topics
-
Networked Standby Power Measurement
The core focus is on power consumed by equipment in "networked standby mode"-a state where devices are connected to a network and can be remotely reactivated to perform functions.
-
Edge Equipment Scope
Applies to edge equipment in household and office settings that have network reactivation functions, including:
- Household appliances
- IT equipment
- Audio, video, and multimedia systems
- Digital radio receivers with emergency functions
- Certain gas burning equipment
-
Measurement Methods and Conditions
The standard provides:
- Testing setup requirements (test room, network port configurations, power supplies)
- Detailed measurement procedures for both mains and battery-powered devices
- Guidance for handling various modes (active, non-active, standby, off, maintenance)
-
Reporting Requirements
Outlines how to document test conditions, configuration, and measured data for transparency and repeatability.
-
Alignment with Related Standards
Harmonizes terms, definitions, and methods with established documents like IEC 62301 for non-networked standby and other product-specific standards.
Applications
EN IEC 63474:2026 is crucial for manufacturers, testing laboratories, and regulatory bodies involved in:
-
Product Development & Compliance
Ensuring new devices meet energy efficiency requirements for networked standby power, including conformity for market access and eco-labeling.
-
Energy Efficiency Programs
Facilitating participation in initiatives or regulations that limit standby energy consumption in connected equipment.
-
Environmental Impact Assessment
Supporting evidence-based calculations of energy consumption in household and office settings, contributing to environmental sustainability goals.
-
Test Labs & Certification Bodies
Providing a uniform framework for test procedures, uncertainty estimation, and documentation required in product certification and market surveillance.
-
Consumer Information & Documentation
Enabling manufacturers to supply clear information to end-users about device behavior in standby, contributing to informed purchasing and responsible usage decisions.
