Fixed firefighting systems - Water mist systems - Part 3: Requirements and test methods for check valves
This document specifies the requirements and describes the test methods for check valves for water mist firefighting systems.
Check valves allow the passage in the direction of flow and they prevent flow in the reverse direction.
This document is applicable to check valves installed in the pipework of water mist firefighting systems.
Ortsfeste Brandbekämpfungsanlagen - Wassernebelsysteme - Teil 3: Anforderungen und Prüfverfahren für Rückschlagventile
Dieses Dokument legt die Anforderungen fest und beschreibt die Prüfverfahren für Rückschlagventile für Wassernebel-Brandbekämpfungsanlagen.
Rückschlagventile lassen den Durchfluss in Durchflussrichtung zu und verhindern den Durchfluss in der umgekehrten Richtung.
Dieses Dokument ist anwendbar für Rückschlagventile, die im Rohrleitungssystem von Wassernebel-Brandbekämpfungs¬anlagen eingebaut sind.
