What is EN 50393-2020?

EN 50393-2020 is a technical standard that provides guidelines and recommendations for the testing and selection of equipment used in hazardous areas. It specifically focuses on electrical apparatus used in explosive atmospheres, where there is a risk of fire or explosion. Such areas can be found in industries such as oil and gas, mining, chemicals, and pharmaceuticals.

Importance of EN 50393-2020

Compliance with EN 50393-2020 is crucial for ensuring the safety of personnel and preventing accidents in hazardous areas. This standard outlines the requirements for designing, manufacturing, and testing electrical equipment to ensure it can operate safely in potentially explosive atmospheres. By following these guidelines, companies can mitigate the risks associated with using electrical apparatus in these environments.

Key requirements of EN 50393-2020

EN 50393-2020 specifies several key requirements that electrical equipment must meet to comply with the standard. Firstly, it establishes clear definitions and classifications for explosive atmospheres and the corresponding equipment protection levels. It also includes guidance on the selection and installation of appropriate electrical apparatus, such as cables, connectors, and junction boxes, to prevent sparks and ignition sources.

The standard emphasizes the importance of conducting thorough testing and inspection of equipment to verify its suitability for use in hazardous areas. This involves assessing factors like temperature resistance, ingress protection, and mechanical strength to ensure the equipment can withstand the harsh conditions often encountered in such environments.


EN 50393-2020 plays a vital role in promoting safety and preventing accidents in hazardous areas. Compliance with this standard ensures that electrical apparatus used in explosive atmospheres is carefully designed, manufactured, and tested to mitigate the risks of fire and explosion. By adhering to the requirements outlined in EN 50393-2020, companies can enhance workplace safety and protect personnel working in these challenging environments.
