BS EN 15534-6:2015EN 15534-6:2015 (E) 5 1 Scope This part of EN 15534 specifies the characteristics of fencing profiles and elements made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or na

24、tural fibre composites (NFC). It is applicable to fencing profiles and elements for non-structural fencing systems. The security systems, perimeter protections, handrails and load bearing applications are out of the scope of this part of EN 15534. Any systems made from profiles in the scope of this

25、part of EN 15534 that are affected by regulations are under the responsibility of the system supplier. EN 15534-1 specifies some of the test methods relevant to this part of EN 15534. NOTE For editorial reasons, in EN 15534 the abbreviation “WPC” is used for “composites made from cellulose-based mat

The tests according to 4.5.6 shall be carried out if the performance is to be declare

33、d by the manufacturer. Initial type testing shall be repeated, whenever a change occurs in the 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 t

34、esting for factory production control purposes are given in Annex A. 4.2 Material The base polymer, from which the material is produced, and the type and content of cellulose-based material shall be declared by the manufacturer. Reprocessable and/or recyclable materials may be used for manufacturing

35、 profiles provided that they satisfy to the 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.

36、 NOTE A scheme for the characterization of plastics waste is given in EN 15347 1 and guideline for the recovery and recycling are given in ISO 15270 2. 4.3 Appearance For production control purposes, the manufacturer shall compare three samples drawn at random from the same profile production batch

37、with a control sample, under the illumination 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 properties When tested in accorda
