35、n This European Standard specifies an up-flow percolation test to determine the leaching behaviour of inorganic and non-volatile organic substances from granular waste materials under standardized percolation conditions. NOTE Validation data for non-volatile organic substances are not currently avai

36、lable, but will be added on revision when available. For the complete characterization of the leaching behaviour of waste under 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

37、 that kind of material irrespective of the parameter to be determined. Waste and sludge samples can contain hazardous (e.g. toxic, reactive, flammable, infectious) substances, which can be liable to biological and/or chemical reaction. Consequently these samples should be handled with special care.

38、Gases which can be produced by microbiological or chemical activity are potentially flammable and will pressurize sealed bottles. Bursting bottles are likely to result in hazardous shrapnel, dust and/or aerosol. National regulations will be followed with respect to all hazards associated with this m

39、ethod. In the different European countries, tests have been developed to characterize and assess the substances which can be leached from waste materials. The release of soluble substances upon contact with water is regarded as one of the main mechanism of release which results in a potential risk t

40、o the environment during life-cycle of waste materials (disposal or re-use scenario). The intent of these tests is to 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

41、 be addressed in one single standard. Procedures to characterize the behaviour of waste materials can generally be divided into three steps, using different tests in relation to the objective. The following test hierarchy is taken from the Landfill Directive1and the Decision on Annex II of this Dire

42、ctive2for disposal of waste. a) Basic characterization constitutes a full characterization of the waste by gathering 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,

43、 consistency, leachability, etc.), information for understanding the behaviour of waste in the considered management scenario, comparison of waste properties against limit values, and detection of key variables (critical parameters as liquid/solid (L/S) ratios, leachant composition, factors controll

44、ing leachability such as pH, redox potential, complexing capacity and physical parameters) for compliance testing and options for simplification of compliance testing. Characterization may deliver ratios between test results from basic characterization and results from simplified test procedures as

45、well as information on a suitable frequency for compliance testing. In addition to the leaching behaviour, the composition 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 tes

46、ting is used to demonstrate that the sample of today fits the population of samples tested before by basic characterization 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 c

47、ompliance test focuses on key variables and leaching behaviour identified by basic characterization tests. Parts of basic characterization tests can also be used for compliance purposes. 1Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste. 2Council Decision 2003/33/EC of 19 Decem

48、ber 2002. DIN EN 14405:2017-05 EN 14405:2017 (E) 6 c) On-site verification tests are used as a rapid check to 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

49、 described in this document is a basic characterization test and falls in category a).
