This Part of EN 964 specifies a method for the determination of the thickness of geotextiles and geotextile-related products at specified pressures and defines the pressure at which the nominal thickness is determined. The method is applicable to all geotextiles and geotextile-related products.
NOTE. The thickness of geotextiles and geotextile-related products should normally be determined by measuring one layer of the product. When two or more layers are used on top of each other in a design, a test may be made in accordance with this European Standard with the agreed number of layers. When testing structured geotextiles or geotextile-related products care should be taken to ensure that the results are meaningful for the particular product.
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.
