CISPR 24 (EN 55024) vs CISPR 35 (EN 55035)

By Compatible Electronics

EN 55024 has been renamed EN 55035; what’s new?

EN 55103-2 and EN 55024 will be withdrawn and now Manufacturers must begin utilizing EN 55035:2017/A11:2020 to demonstrate EMC Directive compliance for CE Marking.

What is EN 55035, and how is it evolving?

EN 55035:2017/A11:2020 takes electromagnetic compatibility of multimedia equipment into account (MME). By adhering to immunity requirements, the standard ensures that such equipment operates within the recommended frequency range and does not interfere with other multimedia devices. The standard combines the EMC immunity requirements for all multimedia equipment that were previously covered by three separate standards: EN 55103-2 (Immunity for Professional Entertainment Lighting and Control), EN 55024 (Immunity for information technology equipment), and EN 55020. (Immunity for sound and television broadcast receivers and associated equipment)

Is EN 55103-2 and EN 55024 still valid?

When such equipment was reclassified to fall under the Radio Equipment Directive as opposed to EMC regulations, EN 55020 was withdrawn. The EN 55103-2 and EN 55024 standards will be retired in July and September of 2022, respectively. EN 55103-2 will be withdrawn on July 28, 2022, while EN 55024 will be withdrawn on September 16, 2022.

After the withdrawal dates, manufacturers will no longer be able to demonstrate compliance with the EMC Directive for CE Marking or rely on a presumption of compliance. Thus, CE Markings on products tested to these standards will no longer be valid.

If they haven’t already, manufacturers will be required to test their products to EN 55035, which is considered a requirement for demonstrating EMC Directive compliance and is aligned with EN 55032 for emissions.

What should I do as an industrialist?

As a manufacturer of multimedia equipment, you must now:

  • a) Review their documentation to ensure that their product has been tested according to the most recent version of the standard; and

  • b) Where applicable, conduct additional testing to bring them up to the current standard and ensure compliance.

  • c) revise technical documentation, test results, and declarations to reflect the new standard and to demonstrate compliance with the law.
