The International Electrotechnical Commission (IEC) officially released IEC 61000-6-3:2026, "Electromagnetic Compatibility (EMC) – Emission Standard for Equipment in Residential Locations," in April 2026, replacing the previous IEC 61000-6-3:2020 edition.
As a generic EMC emission standard, IEC 61000-6-3 applies to electrical and electronic equipment intended for residential, commercial, and light-industrial environments where no dedicated product EMC standard exists.
The new edition introduces several updates to address the rapid growth of wireless charging technologies, smart home devices, IoT applications, and power electronic products. Key changes include:
New Magnetic Field Emission Requirements for Wireless Power Transfer (WPT)
With the increasing adoption of Qi wireless charging, magnetic charging solutions, and various Wireless Power Transfer (WPT) applications, IEC 61000-6-3:2026 introduces magnetic field emission assessment requirements.
Manufacturers of wireless charging products should pay particular attention to potential low-frequency magnetic field emissions in addition to traditional conducted and radiated emission testing.
Expanded Low-Frequency Conducted Emission Requirements
The updated standard introduces emission requirements within the 9 kHz to 150 kHz frequency range to address low-frequency disturbances generated by:
Switching Mode Power Supplies (SMPS)
Inverters
Energy Storage Systems (ESS)
Wireless Power Transfer Systems
As a result, EMC considerations should be incorporated earlier in the product design stage to minimize compliance risks.
Supporting Emerging Smart and Connected Technologies
As wireless connectivity becomes a standard feature in smart home products, IoT devices, networking equipment, and intelligent control systems, the revised standard further clarifies the applicability of EMC emission requirements for these technologies.
This helps manufacturers establish compliance strategies earlier in the development cycle and reduce the risk of redesigns or retesting during certification.
Products Potentially Affected
Industries that should pay particular attention to this update include:
Smart home appliances and consumer electronics
Wi-Fi, Bluetooth, and IoT devices
Wireless charging products (WPT)
Networking and smart home equipment
Energy storage and power electronic systems
Servers and rack-mounted equipment
BTL Recommendation
Manufacturers developing new products, implementing design changes, or preparing for global market access are encouraged to review whether their products incorporate wireless charging functionality or generate low-frequency emissions.
Early evaluation of EMC compliance strategies based on IEC 61000-6-3:2026 can help reduce development risks, avoid certification delays, and accelerate product time-to-market.
BTL will continue monitoring global EMC regulatory and standardization developments while providing comprehensive EMC testing, certification, and technical consulting services to support customers in achieving successful market access worldwide.
