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

Publication date:   Feb 8, 2005

Scope

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.
