This Technical Specification is applicable for determining the leaching behaviour of monolithic wastes under
dynamic conditions. The test is performed under fixed experimental conditions in this document. 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 behaviour 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 equations. The test method applies to low permeable monolithic
materials.
This procedure may not be applicable to materials reacting with the leachant, leading for example to
excessive gas emission or an excessive heat release.
This document 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.
