METHOD AND DEVICE FOR TESTING THE LEAKAGE RESISTANCE OF A MATERIAL

摘要

The invention relates to a method and an apparatus for testing of a material (M), especially of melt granules from a waste treatment plant. In the process, the material (M) is introduced into a liquid (F) and its resistance to leaching is tested. After the material (M) has been introduced into the liquid (F), it is provided that at least one variable of state is changed continuously, discontinuously or periodically, and that, in doing so, the course of the same or a different variable of state is recorded as the test course. Prior to this, under the same conditions but without the material (M) a calibration course is determined. The difference of test course and calibration course is then a measure for the resistance of the material (M) to leaching. The method employs a container (1) for liquid (F) and material (M) with a port for feeding in at least one reagent (R), by means of which at least one variable of state of the liquid (F) is changed. Assigned to the container (1) there is at least one measuring instrument (7) for measuring the test course and calibration course. The measuring instrument (7) is connected to an analysis unit (11).
