Fire resistance tests for service installations - Part 8: Smoke extraction ducts

This part of this European Standard specifies the test methods for fire resisting smoke extraction ducts and is currently restricted to smoke extraction ducts that pass through into other fire compartments. It represents fire exposure of a fully developed fire. This test has been designed to cover both vertical and horizontal smoke extraction ducts. This method of test is only suitable for ducts constructed from non-combustible materials. This method of test is only applicable to fire resisting ducts that have been tested to prEN 1366-1 (ducts A and B).

Feuerwiderstandsversuche an Installationen in Gebäuden - Teil 8: Entrauchungs- leitungen

Der vorliegende Teil dieser Europäischen Norm legt Prüfverfahren für feuer- widerstandsfähige Entrauchungsleitungen fest und ist bis jetzt auf Entrau- chungsleitungen beschränkt, die in weitere Brandbereiche führen. Er stellt dieBrandeinwirkung für einen Vollbrand dar. Diese Prüfung ist sowohl für sen- krechte als auch waagerechte Entrauchungsleitungen vorgesehen. Das Prüfverfah- ren ist nur für Leitungen aus nichtbrennbaren Baustoffen geeignet.

Essai de résistance au feu des installations de service dans les bâtiments - Partie 8: Conduits d'extraction de fumées

La présente partie de la norme européenne définit une méthode d'essai à laquelledoivent être soumis les conduits d'extraction de fumée résistants au feu et n'est applicable, en l'état actuel, qu'aux conduits d'extraction de fumée qui traversent les compartiments de feu. Elle décrit les conditions d'exposition à une combustion vive. Les essais sont conçus pour les conduits d'extraction de fumée verticaux et horizontaux. Ils concernent uniquement les conduits fabriqués avec des matériaux non-combustibles.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 127.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
