19、tory does not comply with EN ISO/IEC 17025 then duplicate samples shall be sent for checking to a laboratory that does meet EN ISO/IEC 17025 on a regular basis, according to a defined process. NOTE 2 The laboratory can be internal to the treatment operator or a third party laboratory. The preparatio

24、e treatment standard for lamps EN 50625-2-1:2014, 5.6 (de-pollution monitoring). 9.2 Analysis methodology According to EN 50625-2-1:2014, 5.6, the limit value for mercury in lamp treatment fractions that shall apply is the following: 10 mg Hg/kg for glass fractions 100 mg Hg/kg for metal and mixed m

25、etal plastic fractions NOTE 1 The 10 mg Hg/kg value is appropriate for glass fractions from all types of lamps. 5 mg Hg/kg is recommended specifically for glass fractions of linear fluorescent tubes (excluding T12). The origin of the 5 mg Hg/kg value in the glass fraction from linear tubes comes fro

26、m the lamp industrys specification for the recycled glass used for new tubes. NOTE 2 The 100 mg Hg/kg value in metal fractions and mixed metal plastics fractions is based on high deviation of results. There is an objective to drive this figure down once more consistent test results are available to

27、support this. For powder-fractions intended to be recycled, a mercury removal technology shall be in place (downstream). 10 Small appliances This clause of CLC/TS 50625-3-1 is not applicable. 11 Protocol for components removed during a batch process This clause of CLC/TS 50625-3-1 is not applicable.

31、describes the sampling procedures, which shall be used to implement the analysis methodology stated in EN 50625-2-1:2014, 5.6. Sampling shall consider guidance in the following standards: CEN/TR 15310-1 to 5 and EN 14899. AA.2 Number and size of samples Samples shall be taken from fractions resultin

32、g: from the lamp treatment during a batch (see also EN 50625-1:2014, Table D.1), or; from longer periods of lamp treatment, which shall not exceed 3 months. The population is this whole amount of fraction produced during treatment of a given input amount. As a minimum, 10 samples shall be taken from

33、 each of the different lamp treatment fractions being analysed. For each lamp fraction, take the 10 single samples and combine them to form one “mixed sample”. Each of the resulting mixed samples for the different fractions shall be reduced to a size suitable for laboratory analysis (see Table AA.1)

34、. The number of samples for analysis depends on the amount of lamps treated per year as follows: - 1 sample per year for 500 t of lamps treated per year - 1 sample every 6 months for 500 t lamps treated per year. The sample size depends on the particles size of the sampled fraction according to Tabl

35、e AA.1.

36、0625-3-2:2016CLC/TS 50625-3-2:2016 16 AA.3 Principles of sampling AA.3.1 Sampling during treatment process The tool used for sampling shall be dimensioned such that the sample taken contains items of all sizes expected to be contained in the output stream. Samples shall be taken at the outlet of a c

37、ontinuous mechanical treatment process, directly from the output flow of the fraction on the whole cross section of the flow profile. Each sample shall be taken at regular intervals specified below but avoiding the start and finish of the treatment process. NOTE Start and the finish of the treatment

38、 process are less representative because separation results might not be representative during this period. The sampling interval is calculated by dividing the period processing the whole input amount by the number of samples to be taken plus 1. To take the sample, the following three circumstances

39、can be distinguished: If the width and the depth of the stream are small, put a sampling container into the stream using a single one-directional action. It is recommended to place the sampling container at 90 to the falling output flow. Hold the sampling container in place for the period specified

40、to gather the specified volume of material. If the width of stream is large and depth is small, insert the container at one end of the stream and, at a uniform rate designed to collect the required amount of material, move the container through the width of the stream to the opposite end. If width a

41、nd depth of stream are large, follow the method as described above but repeat procedure at 90 to the first direction of sampling. AA.3.2 Sampling after a treatment process The sample shall be representative of the whole population. The technique chosen shall depend on the number and size of the cont

42、ainers to collect fractions and the accessibility of fractions. To determine the number of samples required to be taken from each container, divide the numbers of samples by the number of containers containing the related amount to be represented. The location of where the samples shall be taken in

43、one container depends on the number of samples to be taken and shall consider that a container normally is filled from the bottom to the top. The type of sampling tool shall be adjusted to the sampling technique and the size distribution of the fraction. The location where the samples shall be taken

44、 in one container depends on the calculated number of samples to take in each container and for each container the locations should be different in order to achieve a representative sample for the whole batch. AA.4 Mixed sample preparation The aim of the mixing procedure in AA.2 is to obtain a thoro

45、ughly mixed sample from each fraction without it becoming contaminated. NOTE In a protected area it is suggested to install a protective floor covering, preferably unused plastic sheeting, on the ground to avoid any contamination. One technique is the “conical heap method” where a conical heap is fo

46、rmed by successively deposing the material on the peak of the cone in such a way that the sample runs down all sides of the cone. The size of PD CLC/TS 50625-3-2:2016CLC/TS 50625-3-2:2016 17 the tool used for sampling shall be of such that it can accommodate the entire range of particle sizes which

47、are present. AA.5 Mixed sample reduction The mixed sample shall be reduced to comply with the laboratory sample size. After having applied the conical heap method, flatten the cone to form a flat heap of uniform thickness and diameter. Divide in four the flat heap along the two diagonals intersectin

48、g at right angles. Discard one pair of opposite quarters and form the remainder into a stockpile. Repeat this action until the volume of remaining sub-sample is equal to the desired size. AA.6 Packaging of samples Containers for packaging samples shall be closed and airtight. Packaging material shal

49、l not contaminate the sample or adsorb mercury. A back-up sample of the same volume and mixture shall be retained until the analysis results have been returned and considered valid. Containers should be clearly labelled. The label should contain at least an identification of the location, WEEE stream, name of fraction and date of sampling. A colour photograph of the sample shall be taken and added to the batch documentation (see EN 488 and EN 50625-1:2014, Clause 6). PD CLC/TS 50625-3-2:2
