The European Committee for Electrotechnical Standardization (CENELEC) has published the updated industrial EMC emission standard EN 61000-6-4:2026, replacing the previous version and further strengthening electromagnetic emission requirements for industrial environments.

The new standard enhances EMC emission control requirements, with a stronger focus on high-frequency interference suppression and improved testing methodologies that better reflect real operating conditions. Compared with the previous version, it introduces stricter radiated emission limits, expands frequency coverage, and improves evaluation accuracy through operational condition testing.

The standard applies to a wide range of electrical and electronic equipment used in industrial environments, including industrial automation and control systems, power electronics such as drives and switching power supplies, smart distribution and energy management systems, and new energy applications including EV charging systems, photovoltaic and energy storage systems.

The release of EN 61000-6-4:2026 reflects the EU’s continued move toward higher-precision and real-world EMC evaluation. Manufacturers are expected to further optimize electromagnetic design, shielding structures, and compliance testing strategies to meet future CE requirements.

MAXGE continues to closely monitor international standard developments and actively enhances EMC design and certification systems to ensure global compliance and deliver safer and more reliable electrical protection solutions worldwide.
