Quick Guide to EU (EU) 2023/826 Energy Efficiency Regulation
Compliance Starting from IEC 62301 Ed.2 Standby Power Testing
The latest EU energy efficiency regulation (EU) 2023/826 will be fully enforced starting May 9, 2025. The regulation significantly broadens its scope to cover household/office equipment, electrically powered furniture, building devices (e.g., motorized doors, windows, and blinds), low-voltage power supplies under 6 V, portable battery-powered products in fully charged standby mode, as well as printers and simple set-top boxes.
The requirements are more stringent than previous directives
Products covered by the regulation:
The challenge of standby power testing goes far beyond expectations—extremely low current and power levels, high crest factors, and low power factors. This guide helps you quickly understand the EU (EU) 2023/826 regulation and start compliance from IEC 62301 Ed.2. With comprehensive standby power measurement solutions, engineers can design low-power products and precisely capture every milliwatt of energy consumption.

Quick Analysis of the Three Major Challenges in Measuring Standby Power
Low Power, High Crest Factor, and Transient Fluctuations
As energy saving and carbon reduction become core values in product design, standby power determines whether a product can comply with regulations such as Energy Star and the EU ErP Directive. To effectively reduce standby power consumption during product development, the first step is to understand how to measure standby power accurately and correctly.
Measuring standby power is not as simple as reading a "watt" value. The electrical characteristics in standby mode are highly complex, and measurement must overcome the following challenges:
Extremely Low Power and Small Current, prone to waveform distortion
When a power supply operates under light load, most electronic devices in standby only draw short bursts of current at the voltage peaks to recharge internal capacitors. This high crest factor waveform can be missed if the power analyzer’s sampling rate is insufficient, leading to underestimation of actual current and power, and thus distorted results.
Low Power Factor
In standby mode, most current is drawn from capacitive components (such as EMC filters in power supplies). This current merely oscillates back and forth (charging and discharging electric fields) rather than being real power consumption. However, this causes a significant phase shift between voltage and current, resulting in a low power factor.
MICROTEST 7140 Power Analyzer precisely measures true standby power and solves the three pain points—no missed spikes, no lost pulses, no distortion in low power factor waveforms. Measurement error under low power factor conditions is within ±0.1%, ensuring accurate standby power measurement. With a minimum current range of 2.5 mA, it can effectively capture high-crest current waveforms in standby mode. Equipped with 500 kSPS high-speed continuous sampling and supporting integration up to 10,000 hours, it provides reliable Wh-based average power estimation.
IEC 62301 Ed.2 is the key international standard for standby power testing.
It is also the mandatory reference for compliance with the EU Commission Regulation (EC) No. 1275/2008 and for obtaining the U.S. ENERGY STAR certification, requiring tests and reports to be conducted in accordance with this standard.
We will guide you on how to apply proper measurement methods to ensure your products meet regulatory and energy efficiency requirements in global markets.
