Overview
EN IEC 62301:2026 - Measurement of Standby Power for Appliances and Equipment is a key international standard developed by CLC and the International Electrotechnical Commission (IEC). This standard establishes consistent and harmonized methods for measuring the electrical power consumption of appliances and equipment in standby and other non-active modes, such as off mode. By addressing various products powered by AC or DC sources, as well as battery-powered devices, EN IEC 62301:2026 provides a reliable approach for reporting and comparing standby power use-an important factor for energy efficiency and environmental sustainability.
Key Topics
- Scope and Applicability: The standard applies to household appliances, information technology equipment, audio/video systems, multimedia equipment, and even gas-burning equipment equipped with electrical components that exhibit non-active (standby, off, maintenance) modes.
- Measurement Methods: EN IEC 62301:2026 specifies standardized conditions for measuring power consumption, including requirements for test environment, test equipment accuracy, sampling rates, and data logging.
- Modes Defined: It covers the definitions and distinctions between standby mode, off mode, active mode, maintenance mode, and excludes active (operational) as well as networked standby (covered by IEC 63474).
- Data Reporting: The standard outlines comprehensive requirements for reporting measured data, including test parameters, product details, measured values for various modes, and methodological transparency.
- Instrument Performance: There are enhanced guidelines for measurement uncertainty, particularly with low power and fluctuating loads, and the selection and validation of measurement instruments.
Applications
EN IEC 62301:2026 is crucial for a range of stakeholders concerned with energy efficiency, product compliance, and market access:
- Product Manufacturers: Utilize this standard to measure and document standby power consumption during product development, and to demonstrate compliance with energy consumption regulations.
- Test Laboratories: Ensure repeatable, accurate standby power measurements for certification, market surveillance, and product assessment.
- Regulators and Policymakers: Reference EN IEC 62301:2026 when defining minimum energy performance standards related to standby and off mode power, supporting the reduction of "phantom" energy use in appliances and electronic devices.
- Eco-Design and Labelling Programs: Provide credible and comparable data to inform consumers and guide product development toward more energy-efficient options.
- Procurement Professionals: Rely on standardized results to make informed purchasing decisions for energy-efficient equipment.
The standard supports broader environmental goals by enabling precise measurement and comparison of non-active power consumption-a significant and often underestimated contributor to overall energy demand.
