21、Standard, the performance of the product has been defined in terms of a number of type tests. The performance of a roof constructed with these products depends not only on the properties of the product as it is required by this standard, but also on the design, construction and performance of the ro

22、of in relation to the environment and conditions of use. BS EN 502:2013EN 502:2013 (E) 5 1 Scope This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from stainless steel, terne coated, tin coated or organic coated stainless stee

23、l sheet. The European Standard establishes general characteristics, definitions and labelling for the products, together with requirements 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 re

24、quirements or by purchasers to verify that the products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. Products can be prefabricated or semiformed products as well as strip, coil and sheet for on

25、-site-formed applications (e.g. standing seam roofs, roll cap). The European Standard applies to all discontinuously laid and fully supported roofing products made of stainless steel sheet. No requirements for application (e.g. methods of fixing, supporting construction, design of roof system, execu

26、tion of connections and flashings) are included. NOTE The standard deals partly with flat products, partly with formed (prefabricated) products. Requirements for preformed self-supporting roofing products are given in EN 508-3. 2 Normative references The following documents, in whole or in part, are

27、 normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
