EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 14415 testing. This European standard specifies a method for testing the leaching resistance of polymeric or bituminous geosynthetic barriers and the polymeric component of geosynthetic clay barriers in hot water (method A), aqueous alkaline liquids (method B) and organic alcohols (method C).
This European standard defines a method for testing the behavior of geosynthetic barriers in hot water, aqueous alkaline liquids and organic alcohols for washout, visible changes and tensile properties. Leakage of stabilizers can accelerate the oxidation of the geosynthetic barrier.
Sampling of geosynthetic clay barriers will be done in accordance with EN 12226. Bentonite will be removed from the geosynthetic clay barrier with the help of compressed air, washing or any other suitable method. Take one set of test specimens and one set of control specimens.
Weigh the samples and immediately place them in the holder with each sample separated by at least 10 mm from the other samples and the tank wall. Add the liquid and make sure it completely covers the samples. If necessary, equilibrate the samples to prevent them from floating. Only samples based on the same material will be placed in the same liquid bath.
Keep the test temperature of the liquid (method A, method B and method C) constant at (50 ± 2)°C. Completely replenish the volume of fluid at least every 12 to 14 days. Renewal will be done within 30 minutes. Throughout the entire test, the test liquid must be stirred continuously.
