ENV 1187:2002

Test methods for external fire exposure to roofs

This European Standard specifies three methods for determining the performance of roofs to external fire exposure. The three methods assess the performance of roofs under the following conditions:
test 1 - with burning brands
test 2 - with burning brands and wind
test 3 - with burning brands, wind and supplementary radiant heat.
The tests assess the fire spread across the external surface of the roof, the fire spread within the roof, the fire penetration (tests 1 and 3) and the production of flaming droplets or debris falling from the underside of the roof or from the exposed surface (tests 1 and 3).
Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances e.g. ventilators and roof lights.
NOTE   The three tests listed above do not imply any ranking order. Each test stands on its own without the possibility to substitute or exchange one for another.

Prüfverfahren zur Beanspruchung von Bedachungen durch Feuer von außen

Diese Europäische Vornorm beschreibt drei Prüfverfahren, um das Brandverhalten von Bedachungen gegen Feuerbeanspruchung von außen zu ermitteln. Die drei Verfahren beurteilen das Brandverhalten von Bedachungen unter den folgenden Beanspruchungen:
¾ Prüfverfahren 1: Mit Beanspruchung durch Brandsätze
¾ Prüfverfahren 2: Mit Beanspruchung durch Brandsätze und Wind
¾ Prüfverfahren 3: Mit Beanspruchung durch Brandsätze, Wind und zusätzliche Strahlungswärme.
Die Prüfverfahren beurteilen die Brandausbreitung auf der Dachoberfläche, die Brandausbreitung innerhalb des Dachaufbaus, die Durchdringung des Daches durch Feuer (Prüfverfahren 1 und 3) und das Auftreten von brennendem Abtropfen oder brennenden Teilen entweder von der Dachunterseite fallend oder von der beanspruchten Dachoberfläche (Prüfverfahren 1 und 3).
Prüfverfahren 2 und 3 sind nicht zur Beurteilung von geometrisch unregelmäßigen Dächern oder auf Dächern befestigten Anlagen wie Abzüge und Lichtkuppeln geeignet.
ANMERKUNG  Die drei oben angeführten Prüfverfahren geben keine Rangfolge an. Jedes Prüfverfahren ist eigenständig, ohne ein anderes zu ersetzen oder auszutauschen.

Méthodes d'essai pour l'exposition des toitures à un feu extérieur

La présente Prénorme européenne spécifie trois méthodes permettant de déterminer les performances des toitures exposées à un feu extérieur. Les trois méthodes d'essai évaluent les performances des toitures dans les conditions suivantes :
essai 1 - avec brandons enflammés ;
essai 2 - avec brandons enflammés et vent ;
essai 3 - avec brandons enflammés, vent et chaleur rayonnante supplémentaire.
Les essais évaluent la propagation du feu sur la surface extérieure de la toiture, la propagation du feu à l'intérieur de la toiture, la pénétration du feu (essais 1 et 3) et la production de flammèches ou de débris enflammés tombant de la face inférieure de la toiture ou de la surface exposée de la toiture (essais 1 et 3).
Les essais 2 et 3 ne sont pas applicables aux toitures à géométrie irrégulière ou aux accessoires montés sur la toiture (par exemple : ouvrants de ventilation et lanterneaux d'éclairage).
NOTE   Les trois essais énumérés ci-dessus n'impliquent aucun ordre de classement hiérarchique. Chaque essai existe à part entière, sans aucune possibilité de remplacement ou d'échange réciproque.

This European Prestandard (ENV) was approved by CEN on 5 April 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.
