Commission Decision of 6 March 2006 establishing the classes of reaction-to-fire performance for certain construction products as regards wood flooring and solid wood panelling and cladding (notified under document number C(2006) 655) (Text with EEA relevance) (2006/213/EC) (c. 213)

ANNEXU.K.

The tables set out in this Annex, list construction products and/or materials which satisfy all of the requirements for the performance characteristic reaction to fire without need for testing.

CLASSES OF REACTION TO FIRE PERFORMANCE FOR SOLID WOOD PANELLING AND CLADDING

Material^l	Product detail^e	Minimum mean density^f(kg/m³)	Minimum thicknesses, total/minimum^g(mm)	End-use condition^d	Class^c
^a Mounted mechanically on a wood batten support frame, with the gap closed or filled with a substrate of at least class A2 - s1, d0 with minimum density of 10 kg/m³ or filled with a substrate of cellulose insulation material of at least class E and with or without a vapour barrier behind. The wood product shall be designed to be mounted without open joints.
^b Mounted mechanically on a wood batten support frame, with or without an open air gap behind. The wood product shall be designed to be mounted without open joints.
^c Class as provided for in Table 1 of the Annex to Commission Decision 2000/147/EC.
^d An open air gap may include possibility for ventilation behind the product, while a closed air gap will exclude such ventilation. The substrate behind the air gap must be of at least class A2 - s1, d0 with a minimum density of 10 kg/m³. Behind a closed air gap of maximum 20 mm and with vertical wood pieces, the substrate may be of at least class D - s2, d0.
^e Joints include all types of joints, e.g. butt joints and tongue and groove joints.
^f Conditioned according to EN 13238.
^g As illustrated in Figure a below. Profiled area of the exposed side of the panel not more than 20 % of the plane area, or 25 % if measured at both exposed and unexposed side of the panel. For butt joints, the larger thickness applies at the joint interface.
^h Rectangular wood pieces, with or without rounded corners, mounted horizontally or vertically on a support frame and surrounded by air on all sides, mainly used close to other building elements, both in interior and exterior applications.
ⁱ Maximum exposed area (all sides of rectangular wood pieces and wood support frame) not more than 110 % of the total plane area, see Figure b.
^j Other building elements closer than 100 mm from the wood ribbon element (excluding its support frame) must be of at least class A2 - s1, d0, at distances 100 - 300 mm of at least class B - s1, d0 and at distances more than 300 mm of at least class D - s2, d0.
^l Applies also to stairs.
Panelling and cladding^a	Wood pieces with or without tongue and groove and with or without profiled surface	390	9/6	Without air gap or with closed air gap behind	D - s2, d2
Panelling and cladding^a		390	12/8	Without air gap or with closed air gap behind	D - s2, d0
Panelling and cladding^b	Wood pieces with or without tongue and groove and with or without profiled surface	390	9/6	With open air gap ≤ 20 mm behind	D - s2, d0
Panelling and cladding^b		390	18/12	Without air gap or with open air gap behind	D - s2, d0
