# Commission Decision of 15 May 2007 amending Decision 2003/43/EC establishing the classes of reaction-to-fire performance for certain construction products as regards wood-based panels (notified under document number C(2007) 2045) (Text with EEA relevance) (2007/348/EC), Annex Extent: E+W+S+N.I. In the Annex to Decision 2003/43/EC, Table 1 is replaced by the following: ‘ Table 1 Classes of reaction to fire performance for wood-based panels Mounted without an air gap directly against class A1 or A2-s1, d0 products with minimum density 10 kg/m3 or at least class D-s2, d2 products with minimum density 400 kg/m3. A substrate of cellulose insulation material of at least class E may be included if mounted directly against the wood-based panel, but not for floorings. Mounted with an air gap behind. The reverse face of the cavity shall be at least class A2-s1, d0 products with minimum density 10 kg/m3. Mounted with an air gap behind. The reverse face of the cavity shall be at least class D-s2, d2 products with minimum density 400 kg/m3. Veneered, phenol- and melamine-faced panels are included for class excl. floorings. A vapour barrier with a thickness up to 0,4 mm and a mass up to 200 g/m2 can be mounted in between the wood-based panel and a substrate if there are no air gaps in between. Class as provided for in Table 1 of the Annex to Decision 2000/147/EC. Class as provided for in Table 2 of the Annex to Decision 2000/147/EC.
