Geosynthetics - Determination of friction characteristics - Part 1: Direct shear test (ISO 12957-1:2005)

ISO 12957-1:2005 describes a method of determining the friction characteristics of geotextiles and geotextile-related products in contact with a standard sand, i.e. sand with a specified density and moisture content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus.
The procedure can also be used for testing geosynthetic barriers.

Geokunststoffe - Bestimmung der Reibungseigenschaften - Teil 1: Scherkastenversuch (ISO 12957-1:2005)

Diese Norm beschreibt ein Verfahren zur Bestimmung der Reibungskenngrößen von Geotextilien und geotextilverwandten Produkten in Kontakt mit einem Normsand, b ei genormter Dichte, Feuchte, Normalspannung und konstanter Verschiebegeschwi ndigkeit in einem Schergerät. Das Verfahren kann auch für Prüfungen mit Geomembranen/-Dichtungsbahnen benutzt werden.  Das angegebene Verfahren ist ein Inde xprüfverfahren.

Géosynthétiques - Détermination des caractéristiques de frottement - Partie 1: Essai de cisaillement direct (ISO 12957-1:2005)

L'ISO 12957-1:2005 décrit une méthode de détermination des caractéristiques en frottement des géotextiles et des produits apparentés, en contact avec un sable normalisé, à une masse volumique et avec une teneur en humidité spécifiées, sous l'effet d'une contrainte normale et à une vitesse de déplacement constante, en utilisant un dispositif de cisaillement direct.
Le mode opératoire peut également être utilisé pour les essais sur géomembranes et géosynthétiques bentonitiques.
