BS EN 14429 specifies a method for the determination of the influence of pH on the leachability inorganic constituents from a waste material. The equilibrium condition as defined in the standard established by addition of pre-determined amounts of acid or base to reach desired end pH values.
The method described in BS EN 14429 produces eluates, which are subsequently characterized physically and chemically.
BS EN 14429 is a parameter specific test as specified in EN 12920. The application of this method alone is not sufficient for the determination of the detailed leaching behaviour of a waste under specified conditions.
BS EN 14429 on water quality is relevant to:
Leaching is the loss of soluble substances and colloids from the top layers of soil through percolation.
BS EN 14429 specifies a test method for the determination of the influence of pH on the leachability with initial acid/base addition in organic constituents from waste materials.
BS EN 14429 specifies the influence of pH on the leaching behaviour of inorganic and non-volatile organic substances from granular waste materials under standardized conditions.
BS EN 14429 benefits occupational biologists and researchers in understanding the leaching behaviour of inorganic and non-volatile organic substances from granular waste materials. You can determine the leaching behaviour of waste from granular waste by applying BS EN 14429, which can lead to better decomposition of waste and help protect the environment.
