Fire classification of construction products and building elements - Part 5: Classification using data from external fire exposure to roofs tests
This European Standard provides the fire performance classification procedures for roofs/roof coverings exposed to external fire based on the four test methods given in ENV 1187:2002.
For the classification of a roof/roof covering, only those test methods need to be applied for which the corresponding classification is envisaged.
Products are considered in relation to their end use application.
NOTE The distinction between roofs with a steep slope and facades, in terms of the test and classification standard to be applied, may be subject to national regulations.
General information on the four test methods in ENV 1187:2002 is given in Annex A.
Klassifizierung von Bauprodukten und Bauarten zu ihrem Brandverhalten - Teil 5: Klassifizierung mit den Ergebnissen aus Prüfungen von Bedachungen bei Beanspruchung durch Feuer von außen
Diese Europäische Norm legt das Verfahren zur Klassifizierung des Brandverhaltens von Bedachungen/Dachhäuten, die durch Feuer von außen entsprechend den vier Prüfverfahren nach ENV 1187:2002 beansprucht wurden, fest.
Zur Klassifizierung von Bedachungen/Dachhäuten brauchen nur diejenigen Prüfverfahren angewandt zu werden, für die eine entsprechende Klassifizierung angestrebt wird.
Produkte werden in ihrer praktischen Anwendung betrachtet.
ANMERKUNG Die Unterscheidung zwischen Steildächern und Fassaden bezüglich der Prüfnorm und der anzuwendenden Klassifizierungsnorm kann Gegenstand nationaler Regelungen sein.
Allgemeine Informationen zu den vier in ENV 1187:2002 aufgeführten Prüfverfahren sind Anhang A zu entnehmen.
Classement au feu des produits et éléments de construction - Partie 5: Classement utilisant des données d'essais au feu des toitures exposées à un feu extérieur
Cette partie de la Norme européenne spécifie les méthodes de classement de performance au feu des toitures/couvertures de toiture exposées à un feu extérieur basées sur les quatre méthodes d'essais données dans l'ENV 1187:2002.
Pour le classement des toitures/couvertures de toiture, seules ces méthodes d'essai nécessitent être appliquées pour lesquelles le classement est envisagé.
Les produits sont considérés en relation avec leur application d'utilisation finale.
NOTE La distinction entre les toitures avec une pente prononcée et les façades, en termes de norme d'essai et de classement à appliquer, peut être soumise à des réglementations nationales.
L'Annexe A fournit des informations générales sur les quatre méthodes d'essai de l'ENV 1187:2002.

3 Foreword This European Standard (EN 13501-5:2005) 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 June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive. CEN, CENELEC and EOTA committees preparing technical specifications which contain performance requirements against external fire exposure of roofs should make reference to the classification given in this European Standard and not refer directly to any specific fire test method. EN 13501 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 components of normal 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
