EN 61000-6-4:2020, also known as Electromagnetic Compatibility (EMC) - Part 6-4: Generic Standards - Emission standard for industrial environments, is an international EMC standard that specifies the emission limits and compliance requirements for electrical and electronic equipment operating in industrial environments. It was published by the International Electrotechnical Commission (IEC) in 2020.
Importance of EN 61000-6-4:2020
In today's industrial environment, there is a wide range of electrical and electronic equipment used, from machinery and sensors to control panels and communication devices. These devices can produce electromagnetic emissions that may interfere with other equipment or systems, leading to operational disruptions, safety hazards, or even damage to the equipment itself.
The purpose of EN 61000-6-4:2020 is to define the emission limits for different types of equipment in order to ensure that they do not cause harmful interference and are compatible with other equipment in the same environment. Compliance with this standard helps manufacturers, system integrators, and end-users guarantee the smooth operation of their equipment without negatively impacting others.
Emission Limits and Compliance Requirements
EN 61000-6-4:2020 provides specific limits for radiated and conducted emissions at various frequency ranges. It covers a wide range of industrial environments, including manufacturing facilities, power plants, chemical plants, and more. The standard classifies equipment into different categories based on their intended use, such as heavy industrial, light industrial, and residential areas adjacent to industrial premises.
To achieve compliance, manufacturers need to conduct comprehensive testing and measurement of their equipment according to the specific procedures outlined in the standard. This involves assessing the emissions at different points, including power supply terminals and signal ports. The standard also provides guidance on how to mitigate emissions through proper design, shielding, grounding, and filtering techniques.
Summary
EN 61000-6-4:2020 is a crucial international standard that ensures electromagnetic compatibility in industrial environments. By complying with this standard, manufacturers can demonstrate that their equipment meets the required emission limits, ensuring smooth operation alongside other electrical and electronic devices. It ultimately promotes the overall reliability and safety of industrial systems, minimizing the risk of disruptions, equipment damage, or safety hazards caused by electromagnetic interference.
