Fixed firefighting systems - Condensed aerosol extinguishing systems - Part 2: Design, installation and maintenance

This document specifies requirements and describes the methods for the design, installation, testing, maintenance and safety of condensed aerosol extinguishing systems and the characteristics of the extinguishant media and types of fire for which it is a suitable extinguishing medium.
This document also covers the use of condensed aerosol extinguishing systems for total flooding applications in normally unoccupied and unoccupiable areas, primarily related to buildings, plant and other specific applications, utilising electrically non-conducting aerosol fire extinguishants and for which there are sufficient data available to enable validation of performance characteristics by an appropriate independent authority.
This document is intended as a standard covering solely condensed aerosol.
This document is not applicable to explosion suppression applications.
This document is not intended to indicate approval of the extinguishants listed herein by the appropriate authorities, as other extinguishants may be equally acceptable.
This document is applicable to the extinguishants which fulfil CEN/TR 15276-1.

Ortsfeste Brandbekämpfungsanlagen - Löschanlagen für kondensierte Aerosole - Teil 2: Planung, Installation und Wartung

Dieses Dokument legt Anforderungen fest und beschreibt die Verfahren für die Planung, Installation, Prüfung,
Instandhaltung und Sicherheit von Aerosol-Löschanlagen sowie die Kenndaten der Löschmittel und deren
Eignung für die verschiedenen Brände.
Dieses Dokument beschreibt ebenfalls den Einsatz von Löschanlagen für kondensierte Aerosole als
Raumschutzanlagen in gewöhnlich unbesetzten und nicht begehbaren Räumen, hauptsächlich hinsichtlich
Gebäuden, Anlagen und weiteren besonderen Anwendungen, bei denen elektrisch nicht leitende Aerosol-Löschmittel
eingesetzt werden, über die gegenwärtig ausreichend viele Angaben verfügbar sind, so dass ihre
Kenndaten durch eine zuständige, unabhängige Institution bestätigt werden können.
Diese Europäische Norm gilt nicht für die Explosionsunterdrückung.
Dieses Dokument stellt keine Auflistung der von zuständigen Stellen zugelassenen Löschmittel dar, weitere,
hier nicht aufgeführte Löschmittel können ebenfalls akzeptabel sein.

Installations fixes de lutte contre l'incendie - Systèmes d'extinction à aérosol - Partie 2 : Calcul, installation et maintenance

Le présent document spécifie les exigences et décrit les méthodes de conception, d’installation, d’essai, de maintenance et sécurité des systèmes d'extinction à aérosol de condensation et les caractéristiques des agents d'extinction, et les types de feux pour lesquels ils sont appropriés.
Le présent document couvre également l'utilisation des systèmes d'extinction à aérosol de condensation pour des applications de noyage total dans des zones habituellement inoccupées et non occupables, principalement liées aux bâtiments, usines et d'autres applications spécifiques, utilisant des agents extincteurs en aérosol électriquement non conducteurs et pour lesquels des données suffisantes sont disponibles afin de permettre la validation des caractéristiques de performance par une autorité indépendante appropriée.
Ce document ne s’applique qu’aux aérosols de condensation.
Le présent document n'est pas applicable aux applications de suppression d'explosion.
Le présent document n'est pas destiné à indiquer l'approbation des agents extincteurs énumérés ici, par les autorités compétentes, car d'autres agents extincteurs peuvent être également acceptables.
Le présent document s'applique aux agents extincteurs qui satisfont au CEN/TR 15276-1.
