34、d by Technical Committee CEN/TC 444 “Test methods for environmental characterization of solid matrices”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Se

35、ptember 2017, and conflicting national standards shall be withdrawn at the latest by September 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

36、This document supersedes CEN/TS 14405:2004. The following significant technical changes have been implemented in this new edition of the text: the status of the document has been changed from Technical Specification (CEN/TS) into a European Standard; based on CEN ISO/TS 21268-3 and CEN/TS 16637-3 th

37、e option for analysis of non-volatile organic substances has been added; performance data for inorganic substances has been added (see Annex D). This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association This European Standard has

38、been developed primarily to support the requirements for leaching behaviour testing within EU and EFTA countries. This European Standard was elaborated on the basis of: NEN 7343:1995; NT ENVIR 002:1995. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the fo

41、tion 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 available, but will be added on revision when available.

42、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 that kind of material irrespective of the parameter

43、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. Gases which can be produced by microbiological or che

44、mical 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 method. In the different European countries, tests hav

45、e 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 to the environment during life-cycle of waste material

46、s (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 be addressed in one single standard. Procedures to c

47、haracterize 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 Directive2for disposal of waste. a) Basic characterizatio

48、n 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, consistency, leachability, etc.), information for un

49、derstanding 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 controlling 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 well as information on a suitable frequ
