This European Standard shall be given the status o
16、f a national standard, either by publication of an identical text or by endorsement, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. Attention is drawn to the possibility that some of the elements of this document may be the sub
17、ject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 502:1999. In comparison to the previous edition, the following sections have been changed: Table 1, Annex A and Annex B. According to the CEN/CENELEC Int
18、ernal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,

20、tandards concerning roofing products of metal. Roofing products of metal Self supporting products Fully supported products Zinc EN 501 Stainless steel EN 502 Copper EN 504 Steel EN 505 Aluminium EN 507 References regarding Materials Quality assurance Figure 1 Framework of standards In this European
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.
