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.
