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of an identical text or by endorsement, at the latest by April 2008, and conflicting national standards shall be withdrawn at the latest by April 2008. This document supersedes EN 13501-2:2003. 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. 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 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 13501-2:2007 (E) 5 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 Clauses 2 and 7. 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 interprets the functional requirements for the different groups of building elements and explains the method for deriving their classification on the basis of test results for individual elements. EN 13501-2:2007 (E) 6 1 Scope This European Standard specifies the procedure for classification of construction products and building elements using data from fire resistance and smoke leakage tests which are within the direct field of application of the relevant test method. Classification on the basis of extended application is outside the scope of this European Standard. For extended application, however, the same classes are used as specified in this European Standard. This European Standard deals with: a) loadbearing elements without a fire separating function: walls; floors; roofs; beams; columns; balconies; walkways; stairs. b) loadbearing elements with a fire separating function, with or without glazing, services and fixtures: walls; floors; roofs; raised floors. c) products and systems for protecting elements or parts of the works ceilings with no independent fire resistance; fire protective coatings, claddings and screens; d) non-loadbearing elements or parts of works, with or without glazing, services and fixtures: partitions; facades (curtain walls) and external walls; ceilings with independent fire resistance; fire doors and shutters and their closing devices; smoke control doors; conveyor systems and their closures; penetration seals; linear joint seals; service ducts and shafts; chimneys. e) wall and ceiling coverings with fire protection ability. f) lift landing doors which are tested according to EN 81-58 are excluded from this European Standard. Lift landing doors which are tested according to EN 1634-1 are classified in accordance with 7.5.5. Relevant test methods which have been prepared for these elements are listed in Clauses 2 and 7.
