Geotextiles and geotextile-related products - Determination of the long term protection efficiency of geotextiles in contact with geosynthetic barriers

This European Standard is an index test used to determine the efficiency with which a geotextile or geotextile related product will protect a geomembrane or other contact surface against the mechanical long term effects of static point loads. The test is performed on the geotextile or geotextile related product in contact with a deformable pad. NOTE: Other properties relevant to the protection of geomembranes against differing actions are covered by other standards e.g. dynamic perforation is covered in EN 918. A related performance test simulating specific site conditions is described in Annex B.

Geotextilien und geotextilverwandte Produkte - Bestimmung der langfristigen Schutzwirksamkeit von Geotextilien, im Kontakt zu Dichtungsbahnen

Diese Europäische Norm legt ein Indexprüfverfahren fest, mit dessen Hilfe die Wirksamkeit von Geotextilien oder geotextilverwandten Produkten bestimmt werden kann, die dazu vorgesehen sind, Geomembranen oder andere benachbarte Obeflächen gegen die langfristigen mechanischen Auswirkungen von statischen Punktlasten zu schützen.

Géotextiles et produits apparentés - Détermination de l'efficacité de protection à long terme des géotextiles en contact avec les barrières géosynthétiques

La présente Norme européenne est un essai de référence utilisé pour déterminer l'efficacité avec laquelle un géotextile ou un produit apparenté à un géotextile protège une géomembrane ou une autre surface de contact contre les effets mécaniques à long terme des charges statiques ponctuelles.
L'essai est effectué sur le géotextile ou le produit apparenté à un géotextile isolé. Il mesure les déformations subies par un géotextile ou un produit apparenté à un géotextile en contact avec un support déformable.
NOTE   D'autres propriétés relatives à la protection des géomembranes contre différentes actions sont couvertes par d'autres normes, comme par exemple la perforation dynamique qui est traitée dans l'EN 918.
Un essai de performance voisin simulant les conditions spécifiques sur site est décrit dans l'Annexe B.

EN 13719:2002 (E)41 ScopeThis European Standard is an index test used to determine the efficiency with which a geotextile or geotextile-related product will protect a geosynthetic barrier or other contact surface against the mechanical long term effectsof static point loads.The test is performed on the geotextile or geotextile-related product in isolation. It measures the strainsexperienced by a geotextile or geotextile-related product in contact with a deformable pad.NOTE
