What is BS EN 61549:2018?

Introduction

BS EN 61549:2018, also known as IEC 61549:2018, is a British standard that sets guidelines and requirements for the management of electrical equipment used in machinery and industrial applications. It provides a comprehensive framework to ensure safety and reliability in the design, installation, and operation of electrical equipment, particularly with regards to electromagnetic compatibility (EMC).

Understanding EMC

Electromagnetic compatibility refers to the ability of electronic devices and systems to operate without interference in their intended electromagnetic environment. In simple terms, it ensures that devices can coexist and function properly without causing or suffering from electromagnetic disturbances.

BS EN 61549:2018 addresses various aspects of EMC, including emissions, immunity, and testing procedures. The standard specifies limits for electromagnetic emissions from equipment and defines the levels of immunity required to withstand external electromagnetic disturbances. By complying with these guidelines, manufacturers can mitigate the risk of equipment malfunctioning or causing disruption to other devices.

Key Requirements of BS EN 61549:2018

To meet the standards set by BS EN 61549:2018, equipment must undergo rigorous testing procedures to assess its electromagnetic performance. This involves evaluating both emissions and immunity aspects.

When it comes to testing emissions, the standard establishes limits for conducted and radiated emissions, measuring the levels of electromagnetic energy being emitted from the equipment. Exceeding these limits may indicate potential issues with electromagnetic interference.

On the other hand, immunity testing evaluates a device's ability to withstand electromagnetic disturbances caused by external sources, such as power surges or radio frequency signals. The standard outlines specific test methods and criteria for assessing immunity against common sources of interference.

Aside from testing requirements, BS EN 61549:2018 also emphasizes the importance of proper design, installation, and maintenance procedures to ensure electromagnetic compatibility. This includes consideration of factors like equipment grounding, separation distances, and effective shielding measures.

Conclusion

BS EN 61549:2018 plays a crucial role in ensuring the safe and reliable operation of electrical equipment in industrial settings. By adhering to the guidelines set by this standard, manufacturers can minimize the risk of electromagnetic interferences and their associated consequences. The compliance with BS EN 61549:2018 not only protects against malfunctions but also helps foster a working environment where multiple electronic devices can coexist harmoniously without compromising their functionality or safety.
