Fixed firefighting systems - Automatic sprinkler systems - Design, installation and maintenance

This standard specifies requirements and gives recommendations for the design, installation and maintenance of fixed fire sprinkler systems in buildings and industrial plant, and particular requirements for sprinkler systems, which are integral to measures for the protection of life.
This standard covers only the types of sprinkler specified in EN 12259-1 (see annex L).
The requirements and recommendations of this standard are also applicable to any addition, extension, repair or other modification to a sprinkler system. They are not applicable to water spray or deluge systems.
It covers the classification of hazards, provision of water supplies, components to be used, installation and testing of the system, maintenance, and the extension of existing systems, and identifies construction details of buildings which are the minimum necessary for satisfactory performance of sprinkler systems complying with this standard.
This standard does not cover water supplies to systems other than sprinklers. Its requirements can be used as guidance for other fixed fire fighting extinguishing systems, however, provided that any specific requirements for other fire fighting extinguishing supplies are taken into account.
This standard also covers sprinkler system kits.
The requirements are not valid for automatic sprinkler systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry.

Ortsfeste Brandbekämpfungsanlagen - Automatische Sprinkleranlagen - Planung, Installation und Instandhaltung

Diese Norm legt Anforderungen fest und gibt Empfehlungen für die Planung, den Einbau und die Instandhaltung von ortsfesten Sprinkleranlagen in Gebäuden und Industrieanlagen. Sie legt Anforderungen an besondere Sprinkleranlagen fest, die für Maßnahmen zum Schutz des menschlichen Lebens wesentlich sind.
Diese Norm gilt nur für die in EN 12259-1 festgelegten Sprinklerarten (siehe Anhang L).
Die Anforderungen und Empfehlungen dieser Norm gelten auch für jede Ergänzung, Erweiterung, Reparatur oder sonstige Veränderung an Sprinkleranlagen. Sie gelten nicht für Sprühwasser-Löschanlagen.
Diese Norm umfasst die Klassifizierung von Gefahren, die Art der Wasserversorgung, die zu verwendenden Bauteile, den Einbau und die Prüfung der Anlage, die Instandhaltung und Erweiterung bestehender Anlagen. Sie weist Konstruktionsdetails von Gebäuden aus, die für das ordnungsgemäße Funktionieren von Sprinkleranlagen nach dieser Norm erforderlich sind.
Diese Norm gilt nicht für Wasserversorgungen für andere als Sprinkleranlagen. Ihre Anforderungen können als Leitfaden für andere ortsfeste Brandbekämpfungsanlagen verwendet werden, wobei jedoch vorausgesetzt wird, dass für andere Löschmittel besondere Anforderungen zu berücksichtigen sind.
Diese Norm gilt auch für Bausätze von Sprinkleranlagen.
Die Anforderungen gelten nicht für automatische Sprinkleranlagen auf Schiffen, in Flugzeugen, auf Fahrzeugen und mobilen Brandbekämpfungseinrichtungen oder für unterirdische Anlagen in der Bergbauindustrie.

Installations fixes de lutte contre l'incendie - Systèmes d'extinction automatiques du type sprinkleur - Calcul, installation et maintenance

La présente norme spécifie des exigences et fournit des recommandations pour la conception, l'installation et la maintenance d'installations fixes de lutte contre l'incendie de type sprinkleur dans des bâtiments et des installations industrielles et spécifie des exigences particulières pour les systèmes d'extinction de type sprinkleur faisant partie intégrante de mesures de protection des personnes.
La présente norme ne concerne que les types de sprinkleur spécifiés dans l'EN 12259-1 (voir annexe L).
Les exigences et recommandations de la présente norme sont également applicables à tout ajout, extension ou autre modification apportée à un système d'extinction de type sprinkleur. Elles ne sont pas applicables aux installations à pulvérisation d'eau ou de type déluge.
La présente norme couvre la classification des dangers, l'installation de sources d'eau, les éléments à utiliser, l'installation et les essais du système, la maintenance et l'extension de systèmes existants, et elle identifie les détails de construction des bâtiments qui sont nécessaires au fonctionnement satisfaisant des systèmes d'extinction de type sprinkleur conformes à la présente norme.
La présente norme ne couvre pas les sources d'eau alimentant des systèmes autres que les systèmes de type sprinkleur. Cependant, Ses exigences peuvent être utilisées comme guide pour les autres installations fixes de lutte contre l'incendie, ceci sous réserve que les exigences spécifiques à ces autres systèmes de lutte contre l'incendie soient prises en compte également.
La présente norme couvre également les kits de sprinkleurs en kit.
Les exigences ne sont pas valables pour les systèmes d'extinction automatiques de type sprinkleur installés sur des bateaux, dans des aéronefs, sur des véhicules et des engins mobiles d'incendie, ni pour les systèmes d'extinction souterrains dans l'industrie minière.
