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.

This European Standard is an index test used to determine the efficiency with which a geosynthetic product will protect a geosynthetic barrier or other contact surface against the mechanical long term effects of static point loads.
The test is performed on the geosynthetic product in isolation. It measures the strains experienced by a geosynthetic product in contact with a deformable pad.
NOTE   Other properties relevant to the protection of geosynthetic barriers against differing actions are covered by other standards, e.g. dynamic perforation is covered in EN ISO 13433.
A related performance test simulating specific site conditions is described in Annex B (informative).

This document specifies index test methods for determining the compressive creep properties of geosynthetic products. The test specimens are subjected either to normal compressive loading or to a combination of normal compressive loading and shear loading.
The test method with a normal load only (see Clause 5) is the standard method.
The test method in which combined normal and shear loads are applied (see Clause 6) is intended for products that are sensitive to shear failure, i.e. which have a columnar or cuspated structure.
The tests are carried out on dry specimens or on specimens immersed in water. The test is intended to be carried out with the specimen immersed in water when any part of the geosynthetic product contains a hydrophilic polymer.

ISO 13433:2006 specifies a method to determine the resistance of geosynthetics to penetration by a steel cone dropped from a fixed height. The degree of penetration is an indication of the behaviour of the geosynthetic when sharp stones are dropped on its surface.
The method is generally applicable to geosynthetics. However, the validity of this test for some types of products should be considered carefully, as the test principle may not be applicable.

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.
