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. This Technical Specification was elaborated on the basis of: NEN 7343:1995 NT ENVIR 002:1995 This Technical Specification specifies an up-flow percolation test to determine the leaching behaviour of granular waste materials under standardized percolation conditions. Another Technical Specification will be produced to specify a percolation test for simulating conditions of specific scenarios. For a more complete characterization of the leaching behaviour of waste under specified conditions the application of other test methods is required (see ENV 12920).
