This standard specifies the characteristics of cladding 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 document is applicable to extruded profiles but also to tiles manufactured by other plastics processing techniques, e.g. injection moulding. It is not applicable to support rail profiles, cover strip profiles and fastener devices. This document also specifies assessment methods, provisions for the assessment and verification of constancy of performance (AVCP) of these products and includes requirements for marking.
