What is EN 55032:2020?

EN55032:2020 is a technical standard developed by the European Committee for Electrotechnical Standardization (CENELEC) that specifies the emission limits and measurement methods for electronic and electrical equipment within the European Union. It aims to ensure that these devices do not cause electromagnetic disturbances that can interfere with other equipment or hinder radio and telecommunications services.

Why is EN55032:2020 important?

Electronic and electrical equipment, such as computers, televisions, and radios, generate electromagnetic energy during their operation. This energy can radiate into the environment and potentially interfere with the proper functioning of nearby devices. EN55032:2020 sets the limits for unintentional electromagnetic emissions generated by these devices, ensuring that they are within acceptable levels and do not disrupt the performance of critical systems.

Emission Limits and Measurement Methods

EN55032:2020 provides specific limits for conducted and radiated electromagnetic emissions across a range of frequencies. These limits vary depending on the type of device and its intended use. The standard also outlines standardized measurement methods to accurately assess the level of emissions produced by the equipment under test.

Conducted emissions are those that are transmitted through direct connection, such as power cords and cables. Radiated emissions refer to the electromagnetic energy that is emitted wirelessly from the device's enclosure or antenna.

Compliance and Certification

Manufacturers must ensure that their electronic and electrical equipment comply with the requirements set forth in EN55032:2020 before placing them on the market within the European Union. Compliance can be demonstrated through various means, including self-declaration by the manufacturer or third-party certification.

EN55032:2020 is just one of several related standards that regulate electromagnetic compatibility (EMC). Other standards in the EN550 series address specific aspects, such as harmonics and voltage fluctuations. Together, these standards ensure a consistent and reliable level of EMC compliance across a wide range of electronic and electrical devices.
