EN 508 " - - - FOREWORD

This document (EN 508-1:2014) has been prepared by Technical Committee CEN/TC 128 "Roof covering products for discontinuous laying and products for wall cladding", the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2014 and conflicting national standards shall be withdrawn at the latest by November 2014.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 508-1:2008.
EN 508 Roofing products from metal sheet - Specification for self-supporting products of steel, aluminium or stainless steel sheet consists of the following parts:
- Part 1: Steel
- Part 2: Aluminium
- Part 3: Stainless steel
According to the CEN-CENELEC Internal Regulations, the national standards organizations 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, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

ROOFING AND CLADDING PRODUCTS FROM METAL SHEETSPECIFICATION FOR SELF-SUPPORTING OF STEEL,ALUMINIUM OR STAINLESS STEEL SHEET
Part 1: Steel

INTRODUCTION

Figure 1 indicates the position of this European Standard in the CEN framework of standards concerning roofing products of metal.
In this European Standard, the performance of the product has been defined in terms of calculation and a number of type tests.
1 The performance of a roof constructed with these products depends not only on the properties of the product as required by this European Standard, 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 roofing, covering, wall cladding, lining, liner trays and tiles products for discontinuous laying made from metallic coated steel sheet with or without additional organic coatings. Sheets intended to be used with insulation and membranes are also covered.
This European Standard 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 when purchased before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions.
This European Standard applies to all discontinuously laid self-supporting external profiled sheets for roofing covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than 1 m 2 and produced by stamping. These profiled 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 European Standard does not cover products for structural purposes, i.e. it does cover products used in constructions of Class III (according to EN 1993-1-3), it does not cover products used in constructions of Classes I and II (according to EN 1993-1-3) intended to contribute to the global 2 EN 10143, EN 10346, EN 14782, EN ISO 6270-1, EN ISO 6988, or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding selfweight of the metal sheet).
No requirements for supporting construction, design of roof, cladding, lining, tile system and execution of connections and flashings are included.
