This standard specifies a method for the on-site installation, retrieval and
testing of geotextile samples, irrespective of the particular degradation
mechanisms to which they are exposed_
The method is also appropriate to test for mechanical damage, much of which
occurs during installation, and to provide an owner with information about the
state of the geotextile or geotextile-related product in his structure.
NOTE : The durability of geotextiles or geotextile-related products is
assessed by short-term accelerated tests under conditions more
extreme than those experienced in service. In order to establish the
validity of these tests it is essential to compare their predictions with
tests made on material extracted from site_
Diese ÖNORM beschreibt, wie die Proben auf der Baustelle einzubauen sind und wie sie entnommen und geprüft werden, unabhängig von den speziellen Alterungsmechanismen. Dieses Verfahren ist auch als Prüfung für mechanische Schäden geeignet, die oft direkt beim Einbau entstehen, und informiert den Eigentümer über den Zustand seines Bauwerks.
