This European standard is applicable for determining the leaching behavior of monolithic wastes under dynamic conditions. The test is performed under fixed experimental conditions in this standard. This test is aimed at determining the release as a function of time of inorganic constituents from a monolithic waste, when it is put into contact with an aqueous solution (leachant). This Dynamic Monolithic Leaching Test (DMLT) is a parameter specific test as specified in EN 12920 and is therefore not aimed at simulating real situations. The application of this test method alone is not sufficient for the determination of the detailed leaching behaviour of a monolithic waste under specified conditions. In the framework of EN 12920 and in combination with additional chemical information, the test results are used to identify the leaching mechanisms and their relative importance. The intrinsic properties can be used to predict the release of constituents at a given time frame, in order to assess the leaching behavior of monolithic waste materials, placed in different situations or scenarios (including disposal and recycling scenarios). The test method applies to regularly shaped test portions of monolithic wastes with minimum dimensions of 40 mm in all directions, that are assumed to maintain their integrity over a time frame relevant for the considered scenario. The test method applies to test portions for which the geometric surface area can be determined with the help of simple geometric formulas. The test method applies to low permeable monolithic materials.This European Standard has been developed to determine the release of mainly inorganic constituents from wastes. It does not take into account the particular characteristics of organic constituents, nor the consequences of microbiological processes in organic degradable wastes.
