Clay geosynthetic barriers. Determination of permeability to gases Ingestion-build-117251 6 Calibration report1 Scope This International Standard specifies a method for measuring gas flow through a clay geosynthetic barrier. As clay geosynthetic barriers are used to contain gases in long term applications, this test especially focuses on the steady state of the phenomenon. The test is conducted with nitrogen, e. g. N2 ( = 1,75 10 5 Pas, = 1,15 kg m3 at 20 C). The test method and described apparatus allow the measurement of gas flows in the range 0,1 ml min to
