This document specifies test methods for the determination of tensile properties of polymeric geosynthetic barriers (PE (PEHD and PELLD, FPO (EVA, FPP, and PEVLD), PVC-P and EPDM). Method A is suitable for testing polymeric geosynthetic barriers (GBRP), PVC, EPDM and FPO (EVA, FPP and PEVLD), non-reinforced (including 80gsm glass fleece) and without backing. Method B is suitable for testing polymeric geosynthetic barriers (GBRP), PE (HDPE and PELLD), non-reinforced and without backing. Method C is suitable for testing polymeric geosynthetic barriers (GBRP), reinforced and/or with backing. Method D is suitable for measuring modulus (if required) of all non-reinforced products.

This standard specifies methods for screening the resistance of geotextile products to liquids while not subjecting them to external mechanical stress. The standard is applicable to all geotextiles and geotextile related products. Method A applies particularly to polyamides and method B to polyesters and polyamides. The test results should be interpreted in the context of site conditions. NOTE This standard only considers conditions where the specimens are fully immersed in the liquids. Though outside the scope of this standard, the test conditions may be modified to accommodate particular applications, e.g. gaseous media. This standard does not preclude use for test specimens that are pre-treated by some method, e.g. by weathering, aqueous extraction conditions or installation damage.
