Fixed firefighting systems - Components for gas extinguishing systems - Part 13: Requirements and test methods for check valves and non-return valves
This European standard specifies the requirements and describes test methods for check and non-return valves. This standard is applicable to check valves installed between container valve and manifold and non-return valves installed in pilot lines except those valves, which are tested in combination with non-electrical control devices. Non-return and check valves shall allow the passage in the direction of flow and they shall prevent flow in the reverse direction.
Ortsfeste Brandbekämpfungsanlagen - Bauteile für Löschanlagen mit gasförmigen Löschmitteln - Teil 13: Anforderungen und Prüfverfahren für Rückflussverhinderer und Rückschlagventile
Anwendungsbereich
Diese Europäische Norm legt Anforderungen und Prüfverfahren für Rückflussverhinderer und Rück-
schlagventile für CO 2 -Feuerlöschanlagen, Inertgas-Feuerlöschanlagen oder Feuerlöschanlagen mit
halogenierten Kohlenwasserstoffen fest.
Rückflussverhinderer und Rückschlagventile ermöglichen den Durchfluss in Flussrichtung und verhin-
dern ihn in entgegengesetzter Richtung.
Diese Europäische Norm kann angewendet werden auf Rückflussverhinderer, die zwischen Behälter-
ventil und Sammelrohr installiert sind, und auf Rückschlagventile, die in Steuerleitungen installiert sind
außer denjenigen Ventilen, die in Kombination mit nichtelektrischen Steuereinrichtungen geprüft werden.

Installations fixes de lutte contre l'incendie - Eléments d'installation d'extinction a gaz - Partie 13: Exigences et méthodes d'essai pour clapets anti-retour
1 Domaine d'application
La présente Norme européenne spécifie les exigences et décrit les méthodes d'essai applicables aux clapets anti-retour des systemes d'extinction au CO2, a gaz inerte ou halogéné.
Les clapets anti-retour permettent le passage dans le sens de l'écoulement et l'empechent en sens inverse.
La présente Norme européenne est applicable aux clapets anti-retour installés entre la vanne du réservoir et le collecteur et aux clapets anti-retour de circuit de pilotage installés dans les canalisations pilotes, a l'exception de ceux dont les essais sont effectués en les associant aux dispositifs non électriques de commande.
