When applying the methodologies to assess the de-pollution monitoring the sampling protocols shall be used (normative annex). 4.2 Target value methodology This methodology uses the following approach: establish targets: these masses per uni

5、t of input mass are obtained either by using the formula given in 6.2, 7.2, 8.2 and 10.2 or by using the values given in Table C.1 and Table C.2 of Annex C (which are based on the background of comparable studies developed in Europe (see Bibliography); perform a batch process: determine the mass of

6、the specified components removed by performing a batch process according to the methodology of Annex D of EN 50625-1:2014; evaluate the de-pollution performances: compare the results of the batch process with the specified target values. As stated in B.2 of EN 50625-1:2014, to verify the efficiency

7、of de-pollution during the performing of a batch process, corresponding target value(s) shall be reached. PD CLC/TS 50625-3-1:2015CLC/TS 50625-3-1:2015 (E) 8 4.3 Mass Balance methodology This methodology uses the following approach: establish target values in terms of share of a pollutant in the out

8、put compared to the input of this pollutant (100 %); assess the quantity of a defined pollutant in the input of a batch and measure the quantity of that pollutant in the output fraction(s); evaluate the de-pollution performances by comparing the results of the batch process with the specified target

9、 values. As stated in 5.6 and B.1 of EN 50625-1:2014, to verify the efficiency of de-pollution for specific type of WEEE, e.g. temperature exchange equipment, a mass balance shall be performed and the corresponding target values shall be achieved. 4.4 Analysis methodology This methodology uses the f

10、ollowing approach: establish the limits: these values are defined in this Technical Specification and are based on the background of comparable studies and legislation; sample the output fractions: the sample for the analysis shall be prepared according to the sampling procedure defined in this Tech

11、nical Specification; evaluate the analysis results: the concentration of substances shall be determined according to the analysis procedure defined in this Technical Specification; evaluate the de-pollution performance: compare the results of the analysis with the defined limit values. If the result

12、s of the analysis are below the limit values then the performance of de-pollution fulfils the requirements. As required by B.3 and B.4 of EN 50625-1:2014, the quality of de-pollution shall be measured by comparing the results of the analysis with the corresponding limit values. The analysis establis

13、hes the amount of substances or substances that indicate the presence of items included in Annex F of EN 50625-1:2014 in the output fractions (if applicable to the treatment process). A laboratory shall perform the analysis on the samples for the residual amount of PCB, cadmium and bromine. Dependin

14、g on the treatment process used, one of the techniques below, as used in Annexes A and B, shall be used to obtain a representative mixed sample: sampling during a treatment process; post process sampling. NOTE 1 All the sampling protocols are based on EN 14899. Analysis protocols will be implemented

15、 by laboratories. There are many types of physical-chemical analysis and this Technical Specification describes the suitable method for each type of sample. NOTE 2 In related standards and in chemical analysis processing a sample is often called digestion of a sample. Chemical analysis including pro

16、cessing of the samples should be performed by a laboratory that complies with EN ISO/IEC 17025. If the laboratory does not comply with EN ISO/IEC 17025 then duplicate samples PD CLC/TS 50625-3-1:2015CLC/TS 50625-3-1:2015 (E) 9 shall be sent for checking to laboratory that does meet EN ISO/IEC 17025

17、on a regular basis, according to a defined process. NOTE 3 The laboratory can be internal to the treatment operator or a third party laboratory. The preparation of the test portion of the sample to be analyzed shall be carried out according to EN 15002 and then: for cadmium, the digestion of the sam

18、ple and the subsequent analysis shall be carried out by ICP-OES or ICP-MS according to EN 62321-5. As an alternative the digestion shall be carried out according to EN 13656 and the subsequent analysis performed according to EN ISO 11885 or the EN ISO 17294 series; for bromine, the digestion of the

19、sample and the subsequent analysis shall be carried out in accordance with EN 14582; for PCB, the digestion (e.g. homogenization) of the sample and the subsequent analysis shall be carried out in accordance with EN 15308 or US EPA 8082A/2007, quantification of PCBs as congeners. NOTE 4 ICP-OES is an abbreviation for Inductively Coupled Plasma/Optical Emission Spectrometry and ICP-MS is an abbreviation for Inductively Coupled Plasma Mass Spectrometry, which are the two methods of chemical analysis to be used when analyzing cadmium.
