This document specifies a test method for screening the resistance of polymeric geosynthetic barriers to stress cracking. The test is applicable to polyethylene based products which meets at least one of the following requirements: - there is a pronounced yield point; - density of the final product is > 0.939 g/cm3. NOTE – The described method is suitable for conformance testing of smooth surfaced (non-textured) geosynthetic barriers. However the resistance to stress cracking of the resin used in the manufacture of structured surface materials can be evaluated by carrying out the test where structuring is carried out as a separate processing step, on a preformed smooth surface geosynthetic barrier, the test can be performed on the intermediate smooth material. The data are suitable for screening and determination of conformity but not for deriving performance data such as lifetime, unless supported by further evidence
