Interior grade non-FR HPL composite panels with wood-based substrates c Composite panels comprising non-FR grade HPL meeting the requirements of EN 438-3, adhesively bonded to both sides of non-FR grade wood-based core of minimum thickness 12 mm complying with EN 13986, using PVAc or thermosetting adhesive at an application rate of 60 g/m2 to 120 g/m2.
Wood-based core minimum density 600. HPL minimum density 1 350.
12 mm wood-based core with HPL ≥ 0,5 mm bonded to both sides
D-s2,d0 a Either directly fixed (i.e. with no air gap) to a material having a reaction to fire class of A2-s1,d0 or better and a density of at least 600 kg/m3; or mounted on a timber or metal batten support frame, with a non-ventilated (i.e. void open only at the top) air gap of at least 30 mm, the reverse face of the cavity so formed having a reaction to fire classification of A2-s2,d0 or better. b Classes as provided for in Commission Decision 2000/147/EC Annex Table 1. c Complying with this standard.
4.3 Fire resistance 4.3.1 General Fire resistance applies only for panels intended for end-uses subject to resistance to fire regulations, and where the panel is intended to contribute to fire resistance. 4.3.2 Specimen preparation The product tested shall be mounted in a manner representative of the end-use conditions. 4.3.3 Requirement The product shall be tested and classified according to EN 13501-2, and the resulting class or classes with the corresponding end use(s) shall be declared. 4.4 Water vapour permeability 4.4.1 General Water vapour permeability applies only for panels intended for end uses on walls subject to water vapour permeability regulations, and where the panel is intended to contribute to water vapour resistance. 4.4.2 Requirement The water vapour permeability shall either be determined as water vapour resistance factor according to EN ISO 12572, or taken from Table 2.

4.5 Resistance to fixings Resistance to fixings shall be determined as resistance to axial withdrawal of wood screws from the panel face (face screw-holding) according to ISO 13894-1:2000, test method 15, or in the case of Compact panels taken from Table 3. When testing Compact panels a pilot hole, with a diameter 0,5 mm less than the nominal screw size, shall be pre-drilled before inserting the screw.

4.6 Direct airborne sound insulation 4.6.1 General Direct airborne sound insulation applies for panels intended for uses in walls/ceilings subject to acoustic insulation regulations, and where the panel is intended to contribute to sound insulation. Compact panels/sidings and composite panels/sidings are used most of the time as a component of a building element. The acoustic performance is relevant for the building element of which the panel is a part.

EN 438-6:2005, Table 2 for exterior use, and shall be declared as pass results. 4.9 Thermal resistance/conductivity 4.9.1 General Thermal resistance/conductivity applies only for panels intended for end uses on walls/ceilings subject to thermal insulation regulations, and where the panel is intended to contribute to the thermal insulation. 4.9.2 Requirement The thermal conductivity shall be determined in accordance with EN 12664 and the result shall be declared, or it shall be calculated from data taken from EN 12524, where the conductivity of the HPL part of the product shall be taken to be 0,3 W/(m K). 4.10 Release of dangerous substances 4.10.1 Content of pentachlorophenol 4.10.1.1 General Content of pentachlorophenol applies only for wood-based HPL composite panels/sidings.

EN 717-1 requirement EN 717-2 requirement Class E1 ≤ 0,13 mg/m3 air ≤ 3,5 mg/m2 h Class E2 > 0,13 mg/m3 air > 3,5 to ≤ 8,0 mg/m2 h NOTE
For established products, initial type testing may also be done on the basis of existing data from tests carried out in accordance with EN 120 or EN 717-2, either from factory production control or from external inspection.
4.11.2 Sound absorption 4.11.2.1 General Sound absorption applies only for panels intended to be used for acoustical absorbent purposes, and where the panel is intended to contribute to sound absorption. Compact panels/sidings and composite panels/sidings are used most of the time as a component of building element. The acoustic performance is relevant for the building element of which the panel is a part. 4.11.2.2 Requirement If the building element including Compact or composite panels is to be tested for sound absorption, then it shall be tested in accordance with EN ISO 354 and rated in accordance with EN ISO 11654. 4.12 Additional characteristics for external use The thermal shock resistance shall be determined as resistance to climatic shock according to EN 438-2:2005, Test method 19. Compact laminate panels shall comply with the requirement specified for a ‘Pass’ result specified in EN 438-6.
