This document specifies an index test method to determine the friction characteristics of geosynthetics
in contact with a standard sand as described in EN 196-1, i.e. with a specified density and moisture
content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus.
The same testing procedure can be used with any type of soil with the density and moisture content
that are required to evaluate the performance under specific conditions or with another geosynthetic
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.
