Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and UnitedKingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latestby February 2004.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of the Construction Products Directive.CEN, CENELEC and EOTA committees preparing technical specifications which contain performance requirementsagainst resistance to fire tests should make reference to the resistance to fire classification given in this standard andnot refer directly to any specific fire test method.Some of the methods referred to by this standards are prENs which are still undergoing technical development. Usersof this standard should, therefore, check the availability and acceptability of these prENs before seeking to apply them.Currently EN 13501-2 cannot be applied to classify curtain walling for resistance to fire. This will be possible once eitherEN 1364-3 "Fire resistance tests for non-loadbearing elements – Part 3: Curtain walling – Full configuration (completeassembly)" is made available or alternative provisions for classifying curtain walling for resistance to fire are madeavailable.EN 13501 consists of the following parts:Part 1:Classification using test data from reaction to fire testsPart 2:Classification using data from fire resistance tests, excluding ventilation servicesPart 3:Classification using data from fire resistance tests on components of normal building service installationsPart 4:Classification using test data from fire resistance tests on smoke control systemsPart 5:Classification using test data from external fire exposure to roof testsAnnexes A and B are normative.This document includes a Bibliography.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

Further details relating to the practical application of this curve, and other test parameters e.g. tolerances, are given inEN 1363-2.4.4 The ‘semi-natural’ fireDuring the ‘semi-natural’ fire test the temperature of the fire gases adjacent to the soffit of the ceiling shall reach 1000 °C within 10 min to 20 min of the start of the test.Because of the difficulties in achieving the necessary thermal attack in a conventional furnace, the attack shall beprovided by fire from wooden cribs made from softwood.NOTE 1The ‘semi-natural’ fire is a fire which produces direct flame impingement with a high convective heat transfer contentwhich is not realised in furnace tests using the standard temperature/time curve. The term ‘semi-natural’ fire corresponds to thesingle burning item exposure required for ceilings in 4.3.1.3.4 (a) of the Interpretative Document 2 (not to be confused with the“single burning item” test for reaction to fire). It is relevant only for lightweight suspended horizontal protective membraneshaving a low thermal inertia.NOTE 2Further details relating to the practical application of this thermal attack, and other test parameters, are given inprENV 13381-1.
