Introduction

Figure 1 indicates the position of this document in the CEN framework of standards concerning roofing and cladding products of metal sheet.

In this document the performance of the product has been defined in terms of a number of type tests.

The performance of a roof or cladding constructed with these products depends not only on the properties of the product as it is required by this document, but also on the design, construction and performance of the roof or the cladding as a whole in relation to the environment and conditions of use.

Metallic coated aluminium sheet can be easily fabricated. It can be sheared, punched, pressed, drawn, folded, roll-formed without difficulty within the given limits of the properties listed in the respective material specifications.

Coil coated sheet can be fabricated like metallic coated aluminium sheet in most applications, but minimum bend radius, design of forming tools, process temperature etc are chosen according to material properties.

1 Scope

This document specifies requirements for roofing and cladding products used for assembly into coverings for wall claddings, linings and pitched roofs, made from aluminium sheet with or without additional surface treatment (organic coating or anodising).

This document establishes the general characteristics, the definitions and the labelling of 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. This document specifies the requirements for products which enable them to meet all normal service conditions. Products can be prefabricated or semi-formed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs).

This document is applicable to all discontinuously laid and fully supported roofing and cladding products made of aluminium sheets.

This document does not specify requirements for supporting construction, design of roof system and execution of connections and flashings.

This document does not apply to self-supporting aluminium sheets that are covered by EN 508‑2.
