DIN EN ISO 10319:2013-08

This draft International Standard describes an index test method for the determination of the tensile properties of geosynthetics (polymeric, glass and metallic), using a wide-width strip. The method is applicable to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles, felts and metallic products The method is also applicable to geogrids and similar open-structure geotextiles, but specimen dimensions might need to be altered. The method is applicable to metallic products, in particular to double twisted steel wire mesh. This test is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay geosynthetic barriers. The tensile test method covers the measurement of load elongation characteristics and includes procedures for the calculation of secant stiffness, maximum load per unit width and strain at maximum load. Singular points on the load-extension curve are also indicated. Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this draft International Standard.
