What is EN 55016-2-3:2020?

EN 55016-2-3:2020 is a technical standard that specifies the measurement method for radio disturbance characteristics in the frequency range of 10 MHz to 40 GHz. It provides requirements and procedures for electromagnetic compatibility testing of equipment in order to assess its level of radio frequency interference emissions.

Scope

The scope of EN 55016-2-3:2020 covers equipment intended for use in residential, commercial, and light-industrial environments. It applies to all types of equipment and systems that generate or use electromagnetic energy up to 40 GHz, such as telecommunication equipment, information technology equipment, audio and video equipment, lighting equipment, medical equipment, and appliances.

Measurement Methodology

The standard defines the test setup, test limits, and measurement procedures for radiated and conducted disturbances. It includes methods for determining the emission limits and provides guidance on interpreting the results. The measurements are performed using specialized equipment, such as antennas, amplifiers, spectrum analyzers, and measurement receivers.

The radiated disturbance measurements are conducted in an open area test site (OATS) or in a shielded room, while the conducted disturbance measurements are carried out using a power supply network simulator. Different test setups and methods are employed depending on the frequency range and the nature of the equipment being tested.

Compliance and Certification

In order to comply with the EN 55016-2-3:2020 standard, manufacturers need to ensure that their equipment meets the specified emission limits. Compliance testing can be performed either in-house or by accredited testing laboratories. Once compliance is verified, the equipment can be labeled with the CE mark, indicating that it conforms to the European Union's electromagnetic compatibility requirements.

It is important for manufacturers to regularly test and monitor their equipment's emissions, as non-compliance can lead to interference with other nearby electronic devices and may result in product recalls or legal issues. Compliance with the standard also assures consumers that the equipment they purchase will not cause undue interference in their environment.

In conclusion, EN 55016-2-3:2020 is a crucial technical standard that ensures the electromagnetic compatibility of equipment operating in the frequency range from 10 MHz to 40 GHz. By adhering to this standard, manufacturers can meet regulatory requirements and provide users with reliable, interference-free products.
