Clay geosynthetic barriers — Determination of permeability to gases

active, Most Current
Organization: ISO
Publication Date: 1 May 2011
Status: active
Page Count: 14
ICS Code (Geotextiles): 59.080.70
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 (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 5 l/min on specimens with moisture contents in the range of 90 % to 130 %.
