With the new EU Delegated Regulation (EU 2024\/1681), fire dampers (EN 13501-3:2025) are now required to be tested from both sides. <\/strong><\/p>\n\n\n\n

As a result, the term \u201cfire direction\u201d should no longer appear in classifications; however, the fact that the product has been tested from both sides must be clearly indicated in both the classification reports and the certificate. In line with this change, existing certificates must also be updated.<\/p>\n\n\n\n

a) Double Fire Direction:<\/strong>
Previous classifications, (i\u2192o)<\/strong> and (o\u2192i)<\/strong>, are no longer valid.<\/p>\n\n\n\n

b) Blade Axis:<\/strong>
The new classification standard requires that the orientation of the damper blade axis (horizontal\/vertical) be specified in the classifications. Accordingly, certificates issued under EN 15650:2010 must be updated to include this information.<\/p>\n\n\n\n

Additionally, the product standard of EN 15650:2010 still references the older classification standard EN 13501-3:2005 standard, which may give the impression that the old sub-classifications (i\u2192o) are still valid. However, the official position from the European Commission clarifies that regulations take precedence over standards, meaning that the i\u2192o classification is no longer valid. Market surveillance authorities and notified bodies are expected to act in accordance with this.<\/p>\n\n\n\n

The new provisions and changes entered into force on 04\/09\/2025.<\/p>\n\n\n\n
