BS EN 15534-1:2014EN 15534-1:2014 (E) 5 Introduction The denomination “wood-polymer composites”, WPC, is usually used to designate materials or products consisting of one or more natural fibres or flours and one or a mixture of polymer(s). Na

35、tural fibres and flours come from different plant sources (e.g. wood, hemp, flax, sisal, coconut, cotton, kenaf, jute, abaca, banana leaf fibres, bamboo, rice, wheat straw or other fibrous material) and different polymers, virgin or recycled, are used. Currently, the most commonly used polymers are

36、poly(vinyl chloride) (PVC), polypropylene (PP) and polyethylene (PE). WPC materials can be processed by different techniques, as extrusion for profiles, calendering for films and sheets, injection moulding or compression moulding. The contents of natural fibres and polymers depend on the application

37、 and the processing techniques. WPC materials may be considered neither as filled plastics nor as a special kind of wood. They should be considered as different materials having their own characteristics. For the moment, the main applications of WPC products are decking, cladding, panelling and fenc

38、ing and furniture. BS EN 15534-1:2014EN 15534-1:2014 (E) 6 1 Scope This European Standard specifies test methods for the determination of properties of composites made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or natural fibre composites (NFC). N

39、OTE For editorial reasons, in EN 15534 the abbreviation “WPC” is used for “composites made from cellulose-based materials and thermoplastics”. This part of EN 15534 is applicable to cellular or non-cellular compounds and products, made from cellulose-based materials and thermoplastics, intended to b

40、e or being processed through plastics processing techniques, without threshold for the cellulose-based material content. All the properties listed in this part of EN 15534 are not necessarily assessed for a given application. Test parameters and requirements of the test methods for a given applicati

41、on are specified in the relevant part of EN 15534. Profiles for the management of electrical power cables, communication cables and power track systems used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are not covered by EN 155342). 2 Normative r
