EN 12506:2003 (E)3ForewordThis document (EN 12506:2003) has been prepared by Technical Committee CEN/TC 292 "Characterization ofwaste", 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of an identical text orby endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latestby December 2003.This document supersedes ENV 12506:2000.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 12506:2004
EN 12506:2003 (E)4IntroductionThis standard is intended to be used for the characterization of waste as defined in the Council Directive75/442/EEC on waste, as amended by Council Directive 91/156/EEC of 18th March 1991, and national regulations,whose final destination for disposal is landfill.It deals with the determination of pH and chemical constituents which have been extracted by leaching of wastesamples for example using EN 12457 Characterisation of waste - Leaching - Compliance test for leaching ofgranular waste materials and sludges – Part 1 - 4.This European Standard together with EN 13370 is intended to define analytical methods for eluates. A largenumber of compounds can interfere with the determination of the parameters concerned. These potentialinterferences are listed in the individual standards in question.For the analytical determinations ENV ISO 13530 and EN ISO/IEC 17025 should be considered.1 ScopeThis European Standard specifies methods for the determination of the parameters pH, As, Ba, Cd, Cl-, Co, Cr,Cr°VI, Cu, Mo, Ni, NO2-, Pb, total S, SO42-, V and Zn in aqueous eluates for the characterization of waste.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

EN 12506:2003 (E)64 Sample pre-treatmentThe eluate shall be analysed for its total content. If precipitation occurs between the preparation of the eluate andthe analysis it is necessary to ensure by appropriate methods (e.g. redisolution, separate analysis of solution andprecipitate) that the total content of the parameters of interest is determined. If the eluate results from a procedureincluding 0,45 m membrane filtration analytical results refer to the content dissolved by the leaching process.Eluates are susceptible to be changed to different extents as a result of physical, chemical or biological reactionswhich may take place between the time of leaching and the analysis. pH shall be determined immediately afterpreparation of the eluates and prior to sample pre-treatment.It is therefore essential to take the necessary precautions to minimize these reactions and in the case of manyparameters to analyse the eluate sample with a minimum of delay. The maximum delay is given in EN ISO 5667-3or in the analytical standards.Precautions should be taken before and during transport as well as during the time in which the samples arepreserved in the laboratory before being analysed, to avoid alteration of the test portion.Split the eluate in an adequate number of test portions for different chemical analysis and preserve them accordingto the requirements in the analytical standards or EN ISO 5667-3.One specific test portion may be an untreated aliquot of the laboratory sample for analysis of anions such aschloride, sulfate, nitrite and chromium VI.For trace metal analysis test portions usually need to be acidified to pH
2.NOTE 1For safety reasons it is recommended to acidify the test portion under a hood as volatile toxic substances can begenerated.NOTE 2In cases where high contents of soluble solids are leached, acidification of the eluates can lead to precipitation of salts.This can be avoided by dilution prior to acidification.5 Blank determinationThe blank contribution of the analysing procedures shall be determined as described in the analytical standardsand considered in the calculation of the results when appropriate.6 InterferenceSeveral types of interference effects can contribute to inaccuracies in the determination of the various parameters,especially at low concentrations. These potential interference effects are listed in the individual standards and shallbe considered separately for each analytical technique.Chemical interference is characterized by molecular compound formation, ionization effects, solute vaporization,precipitation and effects of decomposition of organic matter. Addition of buffer and/or preservation methods mayreduce these effects.Physical interference can be caused by changes of viscosity and surface tension. They can cause significantinaccuracies especially in eluate samples containing high concentrations of acids and/or dissolved components.The colour or turbidity of eluates can cause interference in spectrometric determination.Standard addition may be used to visualise and correct for interference effects (see ISO 8466-3).SIST EN 12506:2004
EN 12506:2003 (E)77 Selection of the suitable test methodSelect the appropriate standardized test method listed in Table 1 according to the type of waste eluate, theconcentration range of the parameter of interest and the expected interference.It is pointed out that the standardized test methods listed in Table 1 have primarily been developed for the analysisof water samples. They were validated in a new interlaboratory trial for a limited number of waste eluate matrices(see annex A) performed by CEN/TC 292. Their suitability for other waste eluates has to be checked in thelaboratory performing the analysis.If the methods referred to in Table 1 are found to be inappropriate by reason of, for example, detection limits,repeatability or interference, other methods validated for water analysis such as GF-AAS, ICP-MS can be used.Their suitability for waste eluates has to be checked in the laboratory performing the analysis. The reason for thedeviation shall be stated in the test report.Table 1 — Parameters and test methodsParameterTest methodpHaISO 10523AsEN ISO 11885EN ISO 11969BaEN ISO 11885CdISO 8288EN ISO 11885Cl-ISO 9297EN ISO 10304-1EN ISO 10304-2CoEN ISO 11885CrEN ISO 11885Cr VIISO 11083CuISO 8288EN ISO 11885MoEN ISO 11885NiISO 8288EN ISO 11885NO2-EN 26777EN ISO 10304-1EN ISO 10304-2EN ISO 13395PbISO 8288EN ISO 11885total SEN ISO 11885SO4 2-EN ISO 10304-1EN ISO 10304-2VEN ISO 11885ZnISO 8288EN ISO 11885aat pH < 3 or pH > 10 use the same method but be aware thatinaccuracy can increaseSIST EN 12506:2004
