Fixed firefighting systems - Powder systems - Part 1: Requirements and test methods for components

This document specifies requirements and test methods for materials, construction and performance of components intended for use in powder firefighting systems complying with EN 12416-2:2001+A1:2007.
The components covered are as follows:
-   powder containers;
-   expellant gas container assemblies;
-   pressure regulators and gauges;
-   actuators;
-   main isolating valves and selector valves;
-   nozzles.
The components are suitable for powder firefighting systems for general use in buildings and other construction works. In areas with a risk of explosion, earthquake zones, extreme environmental conditions, e.g. marine, offshore, mining or aircraft additional considerations apply.
This document covers components for use in powder extinguishing systems complying with EN 12416-2:2001+A1:2007. It does not cover, for example, pipes and fittings which are covered by more general standards for which requirements and recommendations are given in EN 12416-2:2001+A1:2007. Nor does it cover fire detectors or electrical control and indicating equipment.

Ortsfeste Brandbekämpfungsanlagen - Pulverlöschanlagen - Teil 1: Anforderungen und Prüfverfahren für Bauteile

Dieses Dokument legt Anforderungen und Prüfverfahren für Werkstoffe, Konstruktion und Leistungsmerkmale von Bauteilen fest, die für die Anwendung in Pulverlöschanlagen nach EN 12416 2:2001+A1:2007 bestimmt sind.
Folgende Bauteile werden beschrieben:
   Pulverbehälter;
   Treibgasbehältergruppen;
   Druckregler und Druckmessgeräte;
   Auslöseeinrichtungen;
   Hauptabsperr- und Bereichsventile;
   Düsen.
Die Bauteile sind für Pulverlöschanlagen für die allgemeine Verwendung in Gebäuden und sonstigen Bauwerken geeignet. Beim Einsatz in explosionsgefährdeten Bereichen, Erdbebengebieten oder unter extremen Umweltbedingungen, wie in der Seefahrt, auf Bohrinseln, im Bergbau oder in der Luftfahrt, können weitere Anforderungen gelten.
Dieses Dokument behandelt Bauteile für die Anwendung in Pulverlöschanlagen nach EN 12416 2:2001+A1:2007. In dem vorliegenden Dokument werden, z. B. Rohre und Fittings, nicht behandelt, die in anderen allgemeinen Normen beschrieben sind und für die Anforderungen und Empfehlungen in EN 12416 2:2001+A1:2007 gegeben werden. Außerdem werden weder Brandmelder noch Brandmelderzentralen behandelt.

Installations fixes de lutte contre l’incendie - Systèmes d’extinction à poudre - Partie 1 : Exigences et méthodes d’essai des éléments constitutifs

Le présent document spécifie les exigences et les méthodes d’essai s’appliquant aux matériaux, à la construction et aux performances des éléments destinés à un usage au sein d’installations de lutte contre l’incendie utilisant de la poudre conformes à l’EN 12416-2:2001+A1:2007.
Les éléments faisant l’objet de la présente norme sont les suivants :
-   réservoirs de poudre ;
-   systèmes de réserve du gaz propulseur ;
-   régulateurs de pression et manomètres de pression ;
-   déclencheurs ;
-   vannes d’isolation principales et vannes directionnelles ;
-   diffuseurs.
Ces éléments sont adaptés aux installations de lutte contre l’incendie d’usage général utilisant de la poudre, situées dans les immeubles et autres ouvrages de construction. Les surfaces où existent des risques d’explosion, ainsi que les zones de tremblement de terre ou celles dans lesquelles règnent des conditions d’environnement extrêmes, telles que les zones marines, de grand large, minières ou aériennes, peuvent faire l’objet de dispositions complémentaires.
Le présent document s’applique aux éléments destinés à un usage au sein de systèmes d’extinction d’incendie à poudre conformes à l’EN 12416-2:2001+A1:2007. Il ne s’applique pas, par exemple, aux tuyaux et raccords faisant l’objet de normes plus générales, dont les exigences et recommandations sont indiquées dans l’EN 12416-2:2001+A1:2007. Par ailleurs, il ne s’applique pas aux détecteurs ni aux équipements électriques de commande ou d’indication.
