European Commission adopts resistance-to-fire performance classes
Construction-product manufacturers must use the Annex classes when declaring resistance-to-fire performance under Regulation (EU) 2024/3110 from 23 June 2026 — declarations not using these classes will not conform.

Change
Commission Delegated Regulation (EU) 2026/557 establishes binding performance classes for the essential characteristic 'resistance to fire' under Regulation (EU) 2024/3110, entering into force 23 June 2026 and directly applicable in all Member States.
Why it matters
The Annex classes create a single binding classification scheme for resistance to fire applicable across the harmonised zone. Manufacturers must use these classes in declarations of performance under Regulation (EU) 2024/3110. Conformity-assessment bodies and testing laboratories must assess and classify against the Annex classes using harmonised technical specifications, European assessment documents, and referenced classification and testing standards.
Implications
- — Construction-product manufacturers must declare the essential characteristic 'resistance to fire' using the specific classes set out in the Annex from 23 June 2026 — declarations that do not use the Annex classes will not conform to Regulation (EU) 2024/3110.
- — Conformity-assessment bodies and testing laboratories must assess and classify resistance-to-fire performance against the Annex classes using harmonised technical specifications, European assessment documents, and referenced classification and testing standards — assessments using other criteria will not satisfy the classification requirement.
