26、 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2013, and conflict
27、ing national standards shall be withdrawn at the latest by March 2013. Attention is drawn to the possibility that some of the elements of this document 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 s
28、upersedes EN 12467:2004. In comparison with the previous edition, the following sections have been changed or added: 3.9, 3.10, 4, 5.1.1, 5.4.3, 5.4.4, Table 7, Table 8, 7.3.2, 7.3.2.4.2, 7.3.3.3, 7.3.3.4, 7.3.7, 7.5.2.2 and Annex C. Annex ZB concerning the EC Directive 76/769/EEC has been deleted.
29、This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. A dist
30、inction has been made between product appraisal (type tests) and factory production control requirements (acceptance tests). The performance of a building part constructed with these sheets depends not only on the properties of the product as required by this document, but also on the design, constr
31、uction and installation of the component as a whole in relation to the environment and conditions of use. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croa
32、tia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and t

34、ablishes methods of inspection and test as well as acceptance conditions for fibre-cement flat sheets, siding shingles and planks (referred to as sheets later in this document) for one or more of the following uses: internal wall and ceiling finishes; external wall and ceiling finishes. Products cov
35、ered by this European Standard can be used for other purposes provided they comply with the relevant application standard, e.g. rigid underlays. This European Standard covers sheets reinforced with fibres of different types as specified in 5.1.1. This European Standard does not cover sheets for fire
36、 protection purposes. This European Standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed sheets. 2 Normative references The following documents, in whole or in part, are normatively referenced in this
