Annotation of standard text ÖNORM EN 12447 :

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Beständigkeit von Geotextilien und geotextilverwandten Produkten gegen Hydrolyse fest, indem Messproben bei erhöhten Temperaturen Wasser ausgesetzt und dann bewertet werden, um die durch diese Einflüsse bedingten Eigenschaftsänderungen zu ermitteln. Das Prüfverfahren ist zur Festlegung einer Mindestanforderung für die Beständigkeit vorgesehen. Die in diesem Dokument beschriebenen Prüfungen erlauben keine Bestimmung von Reduktionsfaktoren. Die in diesem Dokument beschriebenen Prüfungen sind Auswahlprüfverfahren, die die Funktionsfähigkeit eines Produkts über einen bestimmten Zeitraum aufzeigen. Die Referenzfestigkeit und die Restfestigkeit der in diesem Dokument untersuchten Produkte müssen auf dieselbe Art und Weise nach EN 12226 bestimmt werden. Die Prüfung ist auf alle hydrolyseanfälligen Geotextilien und geotextilverwandten Produkte anwendbar, besonders auf Materialien auf Polyester- und Polyamidbasis und zusätzlich auf die Garne, aus denen diese Geotextilien hergestellt sind. Dieses Verfahren ist nicht zur Bestimmung der Beständigkeit von Geotextilien gegen Hydrolyse unter stark sauren oder alkalischen Bedingungen vorgesehen.
