This European Standard shall b
15、e given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2010, and conflicting national standards shall be withdrawn at the latest by November 2010. Attention is drawn to the possibility that some of the elements of this docum
16、ent may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. According to the CEN/CENELEC Inter
17、nal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxemb

BS EN 16002:2010EN 16002:2010 (E) 4 Introduction The test is performed on a standard test configuration, i.e. a load-bearing structure, a layer of insulation material a
19、nd the mechanically fastened membrane(s). For the determination of the performance of the mechanical fastening system (fastener and washer), with or without possible substrates, ETAG 006:2000, Annex D may be used. The suppliers of these mechanical fastening systems should provide the required inform
20、ation. For the calculation of the performance of wind load resistance of the whole roof, see the relevant national and/or international standards. The result of this standard is the resistance to wind load of the flexible sheet expressed as the characteristic load per fastener. Safety factors may be
21、 defined by national regulation and/or within European or national application documents. In principle, the test apparatus may also be used to assess (partially) bonded flexible sheets, but some modifications and additional guidance are needed. This is the reason to limit the scope of this standard
22、to mechanically fastened sheets only. BS EN 16002:2010EN 16002:2010 (E) 5 1 Scope This European Standard specifies a test method to determine the resistance to wind load of mechanically fastened flexible sheets for roof waterproofing. The assessment is limited to the performance of the mechanically
23、fastened flexible sheets only. The test method does not include the determination of the performance of the mechanical fastener and/or the combination of the mechanical fastener and the substrate. 2 Normative references The following referenced documents are indispensable for the application of this
