What is EN 55035:2020?

EN 55035:2020 is a technical standard that sets the limits and methods of measurement for electromagnetic disturbances in audio, video, audio-visual, and entertainment lighting control apparatus. This standard, also known as "Electromagnetic Compatibility (EMC) - Generic Standards: Immunity for Professional Audio, Video, Audio-Visual and Entertainment Lighting Control Apparatus for Professional Use", was developed by the European Committee for Electrotechnical Standardization (CENELEC).

Scope of EN 55035:2020

The scope of EN 55035:2020 covers the emission and immunity requirements for professional audio, video, audio-visual, and entertainment lighting control apparatus. It defines the performance criteria and test levels for these devices to ensure their compatibility with other equipment. The standard specifies various tests that need to be conducted to evaluate the immunity of the apparatus against common electromagnetic disturbances.

Emission and Immunity Requirements

EN 55035:2020 establishes limits for conducted and radiated disturbances produced by the apparatus under test. It also defines the test setups, procedures, and criteria for evaluating the apparatus' immunity against disturbances caused by other equipment or external sources. The standard covers a wide range of frequencies and disturbance types, including conducted disturbances induced by radio-frequency fields and transients, as well as radiated electromagnetic energy.

The emission limits set by EN 55035:2020 ensure that the apparatus does not produce excessive electromagnetic disturbances that may interfere with the operation of other electrical and electronic devices. These limits are based on the type of apparatus and its intended use. On the other hand, the immunity requirements ensure that the apparatus can withstand expected levels of electromagnetic disturbances without suffering from degradation in performance or malfunction.

Compliance and Certification

To ensure compliance with EN 55035:2020, manufacturers of audio, video, audio-visual, and entertainment lighting control apparatus need to conduct proper testing and evaluation. They must verify that their products meet the emission and immunity requirements specified by the standard. Compliance testing should be performed in accredited laboratories using appropriate test methods and equipment.

Once a product successfully meets the requirements of EN 55035:2020, manufacturers can affix the CE marking, indicating that the product conforms to the essential requirements of the applicable directives. This certification demonstrates that the apparatus has been designed and tested to ensure electromagnetic compatibility, reducing the risk of interference with other devices and ensuring their proper functioning in various environments.

In conclusion, EN 55035:2020 is a crucial technical standard for the professional audio, video, audio-visual, and entertainment lighting control industry. It sets the performance criteria and test levels to ensure the compatibility and reliability of these devices in the presence of electromagnetic disturbances. Compliance with this standard allows manufacturers to demonstrate the quality and safety of their products, providing assurance to users and facilitating the smooth operation of diverse electrical and electronic systems.
