Roofing and cladding products from metal sheet - Specification for self-supporting products of steel, aluminium or stainless steel sheet - Part 2: Aluminium
This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering, wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or without surface treatment (additional organic coatings or anodising).
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 made available on the market before being dispatched 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 and liner trays 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 1999 1 4), it does not cover products used in constructions of structural classes I and II (according to EN 1999 1 4) 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 or cladding system and execution of connections and flashings are included.

In this document the performance of the product has been defined in terms of calculation and 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 required by this document, but also on the design, construction and
performance of the roof as a whole in relation to the environment and conditions of use.
1 Scope
This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering,
wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or
without surface treatment (additional organic coatings or anodising).
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 made available on the
market before being dispatched 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 and liner trays with the exception of tiles with a surface area less than 1 m
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 1999-1-4), it does not cover products used in constructions of
structural classes I and II (according to EN 1999-1-4) 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 or cladding system and execution of
connections and flashings are included.
