The classification system for the reaction to fire performance of building products in Europe has been applied to wood‐based panels as being ‘products with known and stable fire performance’. The European classification system includes two sub‐systems, one main system for all construction products except floorings and the other for flooring products. Panel properties such as density, thickness, joints and types of end‐use application including different substrates have been studied thoroughly and are included in the classification. Most wood‐based panels fall in classes D‐s2, d0 or Dfl‐s1 (for floorings). Testing has been performed according to EN 13823 SBI‐Single Burning Item test, EN ISO 9239‐1 Radiant panel test, and EN ISO 11925‐2 Small flame test. Clear relationships between the main Euroclass fire performance parameters and product parameters (such as density and thickness) have been demonstrated. Tables with reaction to fire classification of different wood‐based panels and end‐use applications have been developed in two steps, approved by the European Commission and published in their Official Journal. The table is also included in the harmonized product standard and may be used for CE‐marking.
