n = number of wood pieces per meter

t = thickness of each wood piece, in meter

w = width of each wood piece, in meter

a = exposed area of wood support frame (if any), in m 2 , per m 2 of wood ribbon element

( 1 )   Mounted in accordance with EN ISO 9239-1, on a substrate of at least Class D - s2, d0 and with minimum density of 400 kg/m 3 or with an air gap underneath.

( 2 )   An interlayer of at least Class E and with maximum thickness 3 mm may be included in applications without an air gap, for parquet products with 14 mm thickness or more and for veneered floor coverings.

( 3 )   Class as provided for in Commission Decision 2000/147/EC Annex Table 2.

( 4 )   Type and quantity of surface coatings included are acrylic, polyurethane or soap, 50 - 100 g/m 2 , and oil, 20 - 60 g/m 2 .

( 5 )   Conditioned according to EN 13238 (50 % RH 23 o C).

( 6 )   Substrate at least Class A2 - s1, d0.

( 7 )   Applies also to steps of stairs.

( 8 )   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/m 3 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.

( 9 )   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.

( 10 )   Class as provided for in Table 1 of the Annex to Commission Decision 2000/147/EC.

( 11 )   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/m 3 . 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.

( 12 )   Joints include all types of joints, e.g. butt joints and tongue and groove joints.

( 13 )   Conditioned according to EN 13238.

( 14 )   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.

( 15 )   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.

( 16 )   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.

( 17 )   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.

( 18 )   Applies also to stairs.
