This European Standard describes a test method to determine the chemical resistance of geosynthetics to liquid municipal, agricultural and industrial wastes, using a laboratory immersion procedure. The procedure includes three chemical compounds chosen to initiate known types of chemical degradation, and a synthetic leachate representative of a landfill containing domestic waste. The procedure can also be applied using a site-specific leachate. These options are denoted by methods A to E: method A: hydrolysis under acidic conditions; method B: hydrolysis under basic conditions; method C: solvation/swelling; method D: synthetic leachate; method E: any site-specific leachate; The method of evaluation (see clause 9) differs according to whether the material is a geotextile, a polymeric or bituminous geosynthetic barrier, or a geosynthetic clay barrier. In the case of geosynthetic clay barriers only the polymeric component will be tested.
