Full Description ADOPTED_FROM:EN 15534-4:2014 This European Standard specifies the characteristics of decking profiles and tiles made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or natural fibre composites (NFC), for external use. This part of EN 15534 is applicable to extruded profiles but also to tiles manufactured by other plastics processing techniques, e.g. injection moulding. It is not applicable to kits (i.e. support rail profiles, cover strip profiles and hardware) which are out of the scope of this part of EN 15534. FprEN 15534 1 specifies the test methods relevant to this part of EN 15534. NOTE 1 For load bearing applications, modification factors for bending properties are defined in CEN/TS 15534 2 [1]. NOTE 2 For editorial reasons, in EN 15534 the abbreviation “WPC” is used for “composites made from cellulose-based materials and thermoplastics”.
