What is EN 50848?

EN 50848 is a technical standard that pertains to the measurement of electromagnetic emissions from electrical and electronic equipment. This standard provides guidelines for assessing and limiting the level of electromagnetic emissions generated by various devices.

Standard Significance

EN 50848 plays a crucial role in ensuring electromagnetic compatibility (EMC) of electrical and electronic products. It sets limits on the amount of electromagnetic radiation equipment can emit, allowing for safe operation in various environments. Compliance with this standard helps reduce the interference caused by electromagnetic emissions, which could disrupt the functionality of other nearby electronic devices.

Measurement Methodology

The measurement techniques outlined in EN 50848 involve both radiated and conducted emissions testing. Radiated emissions refer to the electromagnetic radiation emitted through the air, while conducted emissions are those transferred through power or signal cables. The standard specifies specific test setups and procedures to accurately measure the emissions at different frequencies. These tests are typically carried out in specialized laboratories using calibrated equipment.

Limitations and Challenges

While EN 50848 provides valuable guidance, it is important to note that compliance with this standard does not guarantee immunity from interference. Factors such as the proximity of other equipment, installation conditions, and cable routing can impact the overall performance. Additionally, meeting the requirements of this standard may pose challenges for manufacturers, as they need to consider design modifications and incorporate appropriate shielding measures to achieve compliance.
