What is EN 61000-6-4:2020?

The EN 61000-6-4:2020 is a technical standard developed by the European Committee for Electrotechnical Standardization (CENELEC). It provides guidelines and requirements for the electromagnetic compatibility (EMC) of electrical and electronic equipment in industrial environments. The standard aims to ensure that equipment installed in such environments does not generate excessive electromagnetic emissions or experience undue susceptibility to them.

Importance of EN 61000-6-4:2020

EN 61000-6-4:2020 plays a crucial role in maintaining the proper functioning of electronic devices and systems in industrial settings. Industrial environments often contain various sources of electromagnetic interference, such as large machinery, power supplies, and communication systems. Without proper EMC measures, these interferences can disrupt communication signals, cause equipment malfunctions, and even lead to potential hazards.

Key Requirements of EN 61000-6-4:2020

The standard outlines several key requirements for achieving electromagnetic compatibility. These include:

Limiting conducted emissions: Equipment must comply with specific thresholds for electromagnetic emissions generated through its power connections or signal cables.

Immunity to external disturbances: Equipment should be resistant to common electromagnetic disturbances present in industrial environments, such as electrostatic discharge, radiated fields, and voltage sags.

Design considerations: The standard addresses the need for proper grounding, shielding, and filtering techniques during the design and installation phases of electrical and electronic equipment.

Compliance and Certification

Manufacturers and suppliers of electrical and electronic equipment intended for use in industrial environments must comply with the EN 61000-6-4:2020 standard. Compliance is typically demonstrated through testing the equipment's EMC performance, conducted by accredited laboratories. Upon successful testing, a certificate or declaration of conformity is issued, indicating that the equipment meets the requirements set forth by the standard.
