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 July 2006, and conflicting nation
26、al standards shall be withdrawn at the latest by July 2006. This European Standard 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 inf
27、ormative Annex ZA, which is an integral part of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finlan
28、d, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14782:2005 (E) 5 1 Scope This European Standard specifies the terminology, require
29、ments and test methods for factory made self-supporting metal sheets and tiles (for non-structural applications) delivered in the form of manufactured pieces for roofing and wall cladding and lining. This standard also covers ceiling (including internal metal sheet) and soffit applications and casse
30、ttes (see Figure 1). This standard covers self-supporting copper, zinc, steel, aluminium and stainless steel sheet with or without coatings, e.g. metallic, organic, inorganic or multi-layer (see Annex A). A moisture retaining layer intended to reduce the fall of droplets coming from condensation may
31、 be present on the reverse side of the product. This standard also includes rules for marking, labelling and evaluation of conformity. This standard does not cover products for structural purposes, i.e. it does not cover products intended to contribute to the global or partial stability of the build
32、ing structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet). Requirements concerning acoustical and thermal insulation properties are not considered in this standard. This standard does not include calculation or design requirement
33、s with regards to the works, installation techniques or the performance of the installed products.

42、 For the purposes of this European Standard, the terms and definitions given in EN 506:2000, EN 508-1:2000, EN 508-2:2000 and EN 508-3:2000 and the following apply. 3.1 base material coated or non-coated flat sheet or strip (coil) of metal used for the production of a finished product according to t
43、his standard 4 Requirements 4.1 Materials The materials for the self-supporting metal sheets specified in this European Standard shall be in accordance with the relevant material standards listed in EN 506, EN 508-1, EN 508-2 and EN 508-3. 4.2 Nominal thickness The nominal thickness of the self-supp
44、orting metal sheet (excluding any organic, inorganic or multi-layer coating), as defined in the relevant material standards listed in EN 506, EN 508-1, EN 508-2 and EN 508-3, shall be equal to or greater than the values given in Table 1.

46、he value shown. 4.3 Mechanical resistance NOTE The suitability of a sheet for a given application should be determined by calculation or testing according to the specification applicable in the country of use, including the standards implementing the relevant European Standards. 4.3.1 General The me
47、chanical resistance shall be defined from the following aspects: a) intended use, i.e. roof, wall, soffit, ceiling; b) type of metal, i.e. aluminium, copper, stainless steel, steel, zinc; c) nominal thickness of the metal sheet considering where applicable the class of tolerances as defined in EN 50
48、6, EN 508-1, EN 508-2 or EN 508-3; EN 14782:2005 (E) 8 d) grade of metal in relation to its mechanical properties; e) geometry of the product cross-section; f) dimensional tolerances (see 4.7); g) resistance of the roofing products to concentrated forces (see 4.3.2). 4.3.2 Resistance of roofing prod
49、ucts to concentrated forces The resistance of roofing products to concentrated forces shall be evaluated according to Annex B when subject to regulatory requirements and may be evaluated when not subjected to such requirements. This requirement does not apply for ceiling and soffit products, internal lining and external cladding and cassettes. Products intended for use at a span less than or equal to 400 mm, e.g. some tile profiles, are deemed to satisfy this requirement without the need for testing. NOTE In this case, the
