This Part of EN 508 specifies requirements for self-supporting products for roof covering, wall cladding, lining, liner tray and title products for discontinuous laying made from stainless steel sheet with or without additional metallic and/or organic coatings.
This document establishes general characteristics, definitions, classifications 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 requirements 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.
This document applies to all discontinuously laid self-supporting external profiled sheets for roof covering, wall cladding, lining, liner tray and title products with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof 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 document does not cover products for structural purposes, i.e. it does cover products used in structural class III (according to EN 1993-1-3), it does not cover products used in constructions of Structural 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 of permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof system and execution of connections and flashings are included.
