标准范围
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 (η= 1,75 × 10(?5) Pa?s, ρ=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 5l/min on specimens with moisture contents in the range of 90% to 130%.
