DESCRIPTION
BS EN ISO 10773:2011
This standard BS EN ISO 10773:2011 Clay geosynthetic barriers. Determination of permeability to gases is classified in these ICS categories:
- 59.080.70 Geotextiles
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 (
, 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 5 l/min on specimens with moisture contents in the range of 90 % to 130 %.
