EN 55024, “Information technology equipment – Immunity characteristics – Limits and methods of measurement,” has just been updated. The new 2010 Edition with Amendment A1 is now available from Document Center Inc. This is the European adoption of the CISPR 24 (same title, currently Edition 2.1 — the 2nd Edition with Amendment 1 interfiled). It is a harmonized standard for both the 1999/5/EC (Radio and telecommunications terminal equipment) and and the 2004/108/EC (Electromagnetic compatibility).
At the present time, the EN 55024 2010 Edition with Amendment A1 has not finished the process to add the new edition to either of the Harmonized Lists for these two directives. So you’ll have some time to review the new update and determine if it will impact your products.
What is the EN 55024 about? The standard is used for information technology equipment. It covers continuous and transient, conducted and radiated disturbances, including electrostatic discharges (ESD). This includes disturbances within the frequency range from 0 Hz to 400GHz. Requirements and immunity tests are given so that the equipment will perform correctly in a given environment.
What changes does the Amendment 1 make? The changes in the Amendment 1 for EN 55024 are the same as the changes in Amendment 1 for CISPR 24 Edition 2.0. These changes were made to:
- Clauses 4.2.1 and 4.2.3.1,
- Tables 3 and A.1,
- Annex A — Sections A.2.1, A.2.6,
- Annex A — Figures A.6 and A.7,
- Annex H — Section H.2, and
- Annex H — Table H.2.
Why isn’t this new edition of EN 55024 on the Harmonized Lists yet? Protocol for the official adoption of harmonized EN standards by the European Union itself requires an administrative review and then publication in the Official Journal prior to inclusion on the Harmonized Lists. CENELEC expects the amended 2010 Edition to make it through this process by late August of this year.
What Edition of the EN 55024 should I be using right now? Since the amended edition is not officially adopted, both the 2010 Edition and the 2010 Edition with Amendment 1 are current. However, it is only a matter of time before the new update makes it through the process. When it is added to the Harmonized lists, you’ll see the migration date in the second from the right column. This “cessation of presumption of conformity of the superseded document” is the date you’ll need to stop selling any product that does not meet this new Edition’s requirements.
How do I get a copy of the EN 55024? It’s a copyright document and is only distributed as nation-specific editions like BS EN 55024 and SS EN 55024. For now, only the BS EN 55024 has been published. We expect the Amendment 1 to be available separately as part of the SS EN 55024 edition shortly.
