DIN EN 15863:2015-06 EN 15863:2015 (E) 5 Introduction This document has been developed primarily to support the requirements for

33、leaching behaviour testing within EU and EFTA countries. This document specifies a dynamic leaching test for monolithic waste materials, to determine key parameters to address the leaching behaviour of monolithic waste materials. For the complete characterization of the leaching behaviour of waste u

34、nder specified conditions the application of other test methods is required (see EN 12920). Anyone dealing with waste and sludge analysis should be aware of the typical risks of that kind of material irrespective of the parameter to be determined. Waste and sludge samples can contain hazardous (e.g.

35、 toxic, reactive, flammable, infectious) substances, which can be liable to biological and/or chemical reaction. Consequently these samples should be handled with special care. Gases which can be produced by microbiological or chemical activity are potentially flammable and will pressurize sealed bo

36、ttles. Bursting bottles are likely to result in hazardous shrapnel, dust and/or aerosol. National regulations should be followed with respect to all hazards associated with this method. In the different European countries, tests have been developed to characterize and assess the constituents which c

37、an be leached from waste materials. The release of soluble constituents upon contact with water is regarded as one of the main mechanism of release which results in a potential risk to the environment during life-cycle of waste materials (disposal or re-use scenario). The intent of these tests is to

38、 identify the leaching properties of waste materials. The complexity of the leaching process makes simplifications necessary. Not all of the relevant aspects of leaching behaviour can be addressed in one single standard. Procedures to characterize the behaviour of waste materials can generally be di

39、vided into three steps, using different tests in relation to the objective. The following test hierarchy is taken from the Landfill Directive 1)and the Decision on Annex II of this Directive 2)for disposal of waste. a) Basic characterization constitutes a full characterization of the waste by gather

40、ing all the necessary information for a safe management of the waste in the short and long term. Basic characterization may provide information on the waste (type and origin, composition, consistency, leachability, etc.), information for understanding the behaviour of waste in the considered managem

41、ent scenario, comparison of waste properties against limit values, and detection of key variables (critical parameters as liquid/solid (L/S) ratios, leachant composition, factors controlling leachability such as pH, redox potential, complexing capacity and physical parameters) for compliance testing

42、 and options for simplification of compliance testing. Characterization may deliver ratios between test results from basic characterization and results from simplified test procedures as well as information on a suitable frequency for compliance testing. In addition to the leaching behaviour, the co

43、mposition of the waste should be known or determined by testing. The tests used for basic characterization should always include those to be used for compliance testing. b) Compliance testing is used to demonstrate that the sample of today fits the population of samples tested before by basic charac

44、terization and through that, is used to carry out compliance with regulatory limit values. The compliance test should therefore always be part of the basic characterization program. The compliance test focuses on key variables and leaching behaviour identified by basic characterization tests. Parts

45、of basic characterization tests can also be used for compliance purposes. 1) Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste. 2) Council Decision 2003/33/EC of 19 December 2002. DIN EN 15863:2015-06 EN 15863:2015 (E) 6 c) On-site verification tests are used as a rapid check to

46、 confirm that the waste is the same as that which has been subjected to characterization or compliance tests. On-site verification tests are not necessarily leaching tests. The test procedure described in this document is a basic characterization test and falls in category a). According to EN 12920

47、the evaluation of the release of constituents from waste materials in a certain scenario involves the performance of various tests. This document describes one of the parametric test that can be used for such purposes, especially for monolithic waste. The test procedure allows the determination of t

48、he release under dynamic conditions of constituents from a monolithic waste material, as a function of time. This release is calculated from the concentrations of the constituents measured in the solution (eluate) that is collected in a fixed number of separate fractions. Besides, the following test

49、 conditions are fixed: the type of leachant, the temperature, the liquid to surface area ratio (L/S), and the duration of the test. Results of this test, combined with those from other tests (e.g. EN 14429) and the use of more or less sophisticated models, allow the identification of the main leaching mechanisms that can be distinguished, such as diffusion, dissolution of constituents, initial surface wash-off, dissolution of the matrix (see Annex A). These intrinsic properties can be used to predict the release of constituents at a give
