25、f 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

26、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. 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. For dated references, only the edition cited

28、 applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、ype testing shall be performed to demonstrate compliance with the requirements specified in Clause 4 of this part of EN 15534. The tests according to 4.5.7 shall be carried out if the performance is declared by the manufacturer. Initial type testing shall be repeated, whenever a change occurs in the

32、 composition of the product, its geometry or in the production process. In case of a minor change, only the properties which could be influenced by this change shall be tested. NOTE Minimum frequencies of testing for factory production control purposes are given in Annex A. BS EN 15534-4:2014EN 1553

Reprocessable and/or recyclable materials may be used for manufacturing profiles and tiles provided that they satisfy to the

34、provisions of this part of EN 15534. WPC materials are recyclable materials which can be treated in a material recovery process intended to save resources while minimizing harmful emissions into air, water and soil as well as their impacts on human health. NOTE A scheme for the characterization of p

35、lastics waste is given in EN 15347 2 and guidelines for the recovery and recycling are given in ISO 15270 3. 4.3 Appearance For production control purposes, the manufacturer shall compare three samples drawn at random from the same profile/tile production batch with a control sample, under the illum

36、ination conditions defined in EN 15534-1:2014, 6.1. The control samples shall be stored in a dark room and renewed every six months. If a control sample is put in contact with water, it shall be renewed immediately. 4.4 Physical characteristics When tested in accordance with the test methods as spec
