This International Standard specifies a method for measuring gas flow through a clay geosynthetic barrier. As clay geosynthetic barriers are used to seal off gases in long-term applications, this test especially focuses on the steady state of this phenomenon. The test method and described apparatus allow the measurement of gas flows in the range 0,1 ml/min to 5 l/min on specimens with moisture contents in the range of 90 % to 130 %. This International Standard has been prepared by Technical Committee ISO/TC 221 "Geosynthetics", in collaboration with CEN/TC 189 "Geosynthetics" (secretariat: IBN, Belgium). NA 106-01-11 AA "Geotextilien und Geokunststoffe" ("Geotextiles and geosynthetics") of the Textiles and Textile Machinery Standards Committee (Textilnorm) is responsible for the German collaboration.
