25、g profiles and tiles made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or natural fibre composites (NFC), for external or internal use. This part of EN 15534 is applicable to extruded profiles but also to tiles manufactured by other plastics process

26、ing techniques, e.g. injection moulding. It is not applicable to support rail profiles, cover strip profiles and fastener devices which are out of the scope of this part of EN 15534. EN 15534-1 specifies the test methods relevant to this part of EN 15534. NOTE For editorial reasons, in EN 15534 the

27、abbreviation “WPC” is used for “composites made from cellulose-based materials and thermoplastics”. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
