DIN EN 14405:2017-05

This Standard is applicable to determine the leaching behaviour of inorganic constituents from granular waste (without or with size reduction). The waste body is subjected to percolation with water as a function of liquid to solid ratio under specified percolation conditions. The waste is leached under hydraulically dynamic conditions. The method is a once-through column leaching test and the test results establish the distinction between different release patterns, for instance wash-out and release under the influence of interaction with the matrix, when approaching local equilibrium between waste and leachant.
