Foreword
This document (EN 13501-2:2007+A1:2009) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI.
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of an identical text or by endorsement, at the latest by March 2010, and conflicting national standards shall be withdrawn at the latest by March 2010.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CEN ELEC] shall not be held responsible for identifying any or all such patent rights.
This document includes Amendment 1, approved by CEN on 2009-07-17.
This document supersedes B) EN 13501-2:2007 <5].
The start and finish of text introduced or altered by amendment is indicated in the text by tags The first edition of this European Standard was prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, supporting essential requirements of the Construction Products Directive.
B) Amendment 1 provides for the use of extended application reports in the classification procedure. O
CEN, CENELEC and EOTA committees preparing technical specifications which contain performance requirements against resistance to fire tests should make reference to the resistance to fire classification given in this European Standard and not refer directly to any specific fire test method.
Changes have been made in this revision to bring it in line with the relevant current EC Decisions on fire resistance classification, and experience in use in the first edition.
EN 13501 Fire classification of construction products and building elements consists of the following Parts:
Part 1: Classification using data from reaction to fire tests
Part 2: Classification using data from fire resistance tests, excluding ventilation services
Part 3: Classification using data from fire resistance tests on products and elements used in building service installations: fire resisting ducts and fire dampers
Part 4: Classification using data from fire resistance tests on components of smoke control systems
Part 5: Classification using data from external fire exposure to roof tests

Introduction
The aim of this European Standard is to define a harmonised procedure for the classification for resistance to fire of construction products and building elements. This classification is based on the test procedures listed in E) Clause 2 and the relevant field of application procedures
This European Standard is prepared in support of the second essential requirement in the EC Construction Products Directive (89/106/EEC) which is detailed in the Interpretative Document number 2 (ID2): Safety in case of fire (OJ C62 Vol 37). It reflects the Commission Decision of 3 May 2000 on the implementation of the Council Directive 89/106/EEC as regards the classification of the resistance to fire performance of construction products, construction works and parts thereof.
The Interpretative Document and the Commission Decision of 2 May 2000 specify performance and classes regarding fire resistance. These classes are identified by designation letters, each of which refers to an important characteristic of fire resistance behaviour.
This European Standard provides for a common understanding for these requirements. It i
