DIN EN ISO 10319:2015-09

This 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. This method is applicable to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles, geonets, geomats, and metallic products. The method is also applicable to geogrids and similar open-structure geotextiles, but specimen dimensions need to be altered, if required. The method is applicable to metal products, in particular, double twisted steel wire mesh. This method 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 International Standard. The committee responsible for this standard is NA 106-01-11 AA "Geotextilien und Geokunststoff; SpA zu CEN/TC 189 und ISO/TC 221" ("Geotextiles and geosynthetics; mirror committee to CEN/TC 189 and ISO/TC 221") at DIN.
