1.1 This Korean Industrial Standard specifies a method for the determination of the thickness of geotextiles at specified pressures and defines the pressure at which the nominal thickness is determined.
The test results are intended for identification purposes and for use in technical data sheets and/or as part of other test methods, e.g. tests of hydraulic properties.
1.2 The method is applicable to all geotextiles, but not necessarily to all geotextile-related products such as geogrids.
Remark Normally the thickness of a geotextile is determined by measuring one layer of the geotextile. In cases when two or more layers are used on top of each other in a design, the test may be made in accordance with this International Standard with the agreed number of layers instead of one. In such cases when testing structured geotextiles, consideration should be given to the relevance of such findings.
