Geosynthetics - Determination of friction characteristics - Part 2 : inclined plane test

ISO 12957-2:2005 describes a method of determining the friction characteristics of geosynthetics (geotextiles and geotextile-related products, geosynthetic barriers), in contact with soils, at low normal stress, using an inclining plane apparatus. This method is primarily intended as a performance test to be used with site-specific soils but may also be used as an index test with standard sand. Test data obtained for geogrids tested with a rigid support are not necessarily realistic as the results depend on the friction support.

Geomembranes. Measurement of the geomembrane lining systems slipping angle by means of an inclined plane test.

Le présent document définit une méthode de détermination, à l'aide d'un plan incliné, de l'angle de glissement des différentes interfaces d'un DEG (dispositif d'étanchéité par géomembrane) tels que : sol (ou matériau rigide), géomembrane, géotextile, Les résultats obtenus permettent d'analyser la stabilité au glissement des DEG avec les sols et les matériaux utilisés sur le chantier, dans le cas de faibles contraintes normales. Cette méthode d'essai constitue un essai de performance ; elle complète l'essai d'identification défini par la norme NF P 84-505.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
