What is EN 50037

EN50037 is a technical standard that defines the requirements for electromagnetic compatibility (EMC) of electrical and electronic devices, particularly those used in industrial environments. It provides guidelines for ensuring that these devices do not interfere with each other, and can function properly even in the presence of external electromagnetic disturbances.

Scope and Application

The scope of EN50037 covers a wide range of equipment used in industrial settings, such as machinery, control systems, measurement and monitoring devices, and communication equipment. It applies to both new and existing installations, and addresses various aspects of EMC including emission limits, immunity requirements, and engineering practices.

Emission Limits

One of the key aspects of EN50037 is setting emission limits for devices. This ensures that devices do not emit excessive electromagnetic radiation that could interfere with the operation of other nearby devices. The standard specifies different limits depending on the frequency range and the type of equipment. By complying with these limits, manufacturers can ensure that their devices are compatible with others in the same environment.

Immunity Requirements

In addition to emission limits, EN50037 also sets immunity requirements for devices. These requirements define the level of resistance a device must have to external electromagnetic disturbances. This includes immunity against static electricity, radiated electromagnetic fields, power frequency magnetic fields, and voltage dips and interruptions. By meeting these requirements, devices can function reliably even when exposed to challenging electromagnetic conditions.

Overall, EN50037 plays a crucial role in ensuring the smooth operation of electrical and electronic devices in industrial settings. It helps manufacturers design and produce devices that are compatible with each other, reducing the risk of interference and enhancing overall system reliability. Adhering to the requirements of EN50037 can also help companies meet regulatory standards and improve the safety and performance of their products.
