This Technical Specification is applicable to determine the leaching behaviour of inorganic constituents from granular waste (without or with size reduction (see 6.2)). 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.
