This European Standard specifies a method for measuring the steady-state liquid flow through a geosynthetic
barrier, used to contain liquids in long-term applications.
The test method and described apparatus allow the measurement of flows accurately down to 10-6 m3/m2/day.
In particular circumstances where testing indicates that values obtained for a geosynthetic barrier lie below the
threshold of sensitivity of this test method, then the value of liquid flow is declared as being less than
10-6 m3/m2/day.
Due to its long duration this test method is not suitable for production control testing.
Geosynthetic clay liners cannot be tested with this apparatus.
