BS EN 508-1:2014EN 508-1:2014 (E) 5 Introduction Figure 1 indicates the position of this European Standard in the CEN framework of standards concerning roofing products of metal. Figure 1 Framework of standards In this Eur
26、opean Standard, the performance of the product has been defined in terms of calculation and a number of type tests. The performance of a roof constructed with these products depends not only on the properties of the product as required by this European Standard, but also on the design, construction
27、and performance of the roof as a whole in relation to the environment and conditions of use. BS EN 508-1:2014EN 508-1:2014 (E) 6 1 Scope This part of EN 508 specifies requirements for self-supporting roofing, covering, wall cladding, lining, liner trays and tiles products for discontinuous laying ma
28、de from metallic coated steel sheet with or without additional organic coatings. Sheets intended to be used with insulation and membranes are also covered. This European Standard establishes general characteristics, definitions, classifications and labelling for the products, together with requireme
29、nts for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply when purchased before they are despatched from the factory. It specifies
30、 the requirements for products which enable them to meet all normal service conditions. This European Standard applies to all discontinuously laid self-supporting external profiled sheets for roofing covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less
31、 than 1 m2and produced by stamping. These profiled sheets are designed to keep wind, rain and snow out of the building and to transfer any resultant loads and infrequent maintenance loads to the structure. This European Standard does not cover products for structural purposes, i.e. it does cover pro
32、ducts used in constructions of Class III (according to EN 1993-1-3), it does not cover products used in constructions of Classes I and II (according to EN 1993-1-3) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to pe
33、rmanent static loads (excluding self-weight of the metal sheet). No requirements for supporting construction, design of roof, cladding, lining, tile system and execution of connections and flashings are included. 2 Normative references The following documents, in whole or in part, are normatively re
