NOTE EN 14899:2005 (Characterizati

23、on of waste, Sampling of waste materials, Framework for the preparation and application of a sampling plan) contains basic sampling requirements. The sampling and subsequent sample preparation shall be carried out by someone who has the requisite competence. When conducting sampling, appropriate per

24、sonal protective equipment shall be used, in accordance with the facility requirements and current regulations. Two similar samples have to be taken in each case of sampling: One sample is for laboratory analysis and the other one has to be kept as backup for minimum 1 year. Sample bottles and other

25、 sample vessels should be clearly labelled. The label shall contain at least the name of the treatment facility (or a code), WEEE stream, location of sampling, name of fraction and date of sampling. PD CLC/TS 50574-2:2014CLC/TS 50574-2:2014 - 12 - 12 Bottles and sample vessels shall be selected acco

26、rding to the requirements of the contents concerning pressure and gas tightness. Because of the high-volatility of VFCs and VHCs, all samples containing these substances shall be sent as quickly as possible to the laboratory and store them between 1C and 4C whenever possible. The control sample has

27、to be stored at temperatures within a range from 1C to 4C. Photos of samples shall be taken and recorded. 8.2.2 Sampling of oil as base for the determination of residual VFC content This clause refers to 5.2 (3), 5.6 (1), 5.7 (2) and A.2.6 (f) and A.2.7 of EN 50574:2012. To ensure that the sample is

28、 representative for the complete circle of step 1 production (excluding oil coming from other sources), the sample shall be taken from oil that has undergone full treatment. The sampled oil shall be stored in a gastight vessel. The sample shall be taken at mid-height. Sampling vessel shall be filled

29、 up to top. NOTE The oil from the step 1 test on base of Annex A of EN 50574:2012, taken out of the tank to establish the mass balance might not have been fully degassed yet. Volume and mass of the sample should fit with the requirements of the laboratory. 8.2.3 Sampling of refrigerant as base for t

30、he determination of the chemical composition This clause refers to 5.2 (5), 5.5 (3), 5.6 (1) and Annex A of EN 50574:2012. As the sampling process is a part of the analysing, it is described in 8.2.2. NOTE Mobile gas analysers for refrigerants for sampling and analysing in one step can be used. 8.2.

31、4 Sampling of PU fraction as base for the determination of residual VFC, VHC and foreign matters content 8.2.4.1 General This clause refers to 5.3 (5), 5.6 (1), 5.7 (4) (5) and B.2.5.2 (a) (b) of EN 50574:2012. 8.2.4.2 Number and size of the sample Table 1 PU foam form Minimum vol. of single sample

PD CLC/TS 50574-2:2014- 13 - CLC/TS 50574-2:2014 13 8.2.4.3 Sampling technique Depending on the design of the process, one of the following techniques shall be used: a) Method 1: Sampling from a falling stream In this method,

34、samples are to be taken regularly at the outlet of a continuous mechanical treatment process The sampling period shall correspond to the processing time of 1000 appliances of input material. To define the sampling interval, the required processing time of the input material has to be divided by 10.

35、The first sample has to be taken after half of the time of the first calculated interval. The rest of the samples have to be taken at the calculated sampling intervals. If PU foam is in pellet form or powder samples shall be taken directly from the output flow of the fraction over the whole cross se

36、ction of the flow profile by applying the calculated sampling interval. If PU foam is in briquette form, one briquette per sampling interval shall be sampled. b) Method 2: Sampling from the container If it is not possible to sample the PU directly from a falling stream because PU is stored in closed

37、 containers, 10 single samples shall be taken directly in storage containers after the test. To determine the number of samples in each container, divide 10 by the number of containers containing the fraction corresponding to the input quantity. The location of where the samples shall be taken in on

38、e container is indicated in the picture below, depending on the calculated number of samples to take in each container. On the following pictures, the brown square stands for a top view of one container of the fraction to sample, and the red points indicate where, in this top view of the container,

39、shall be taken the samples, depending on the calculated number of samples to take per container. Samples are always taken on the top layer of the container.

41、014CLC/TS 50574-2:2014 - 14 - 14 For pellets and powder samples, after having applied the conical heap method, flatten the cone to form a flat heap of uniform thickness and diameter. Using a shovel inserted vertically into the material, divide the flat heap into four along two diagonals, intersectin

42、g at right angles. Discard one pair of opposite quarters and shovel the remainder into a stockpile. Repeat this action until the volume of remaining subsample is equal to the desired size. For briquette samples, randomly select 3 briquettes. From the same reduction operation, form 2 samples: The fir

43、st one for the analysis in laboratory The second one shall be retained for a minimum of 1 year in case further analysis is required. 8.2.5 Sampling of metallic and plastics fractions as base for the determination of remaining PU parts 8.2.5.1 General This clause refers to 5.3 (4), 5.6 (1), 5.7 (5 an

44、d 6) and B.2.5.2 (e) of EN 50574:2012. The sampling period shall correspond to the processing time of 1000 appliances of input material. This period varies depending on the recycling process. 8.2.5.2 Number and size of the sample Metallic and plastics fractions are sampled with a minimum of 5 single

45、 samples. These 5 single samples are mixed in order to form a mixed sample, which is then reduced at the size of the sample to be analysed. Table 2 Min. vol. of single sample Min. vol. of mixed sample Amount of sample to be analysed 1 l 5 l 1 l 8.2.5.3 Sampling technique To define the sampling inter

46、val, the required processing time of the input materials has to be divided by 5. Sampling shall be carried out at regular intervals. The first sample has to be done after half of the time of the first sampling interval. This applies for each single fraction (ferrous-metal, NON - ferrous metals, plas

47、tics or mix of them). Depending on the design of the process, one of the techniques as described in 8.2.4.3 shall be used. 8.2.5.4 Mixed sample reduction The same method as in 8.2.4.4 is applied. 8.2.6 Sampling of blowing agents as base for the determination of chemical composition This clause refer

48、s to the following clauses of EN 50574: 5.3:2012 (6), 5.5 (6), 5.6 (1), B.2.5.1 and B.2.5.2. The water volume in the vessel has to be determined before the samples are taken. PD CLC/TS 50574-2:2014- 15 - CLC/TS 50574-2:2014 15 NOTE Measurement systems in the vessel or implemented in the plant itself

49、 are deemed to be appropriate if there is a clear indication for the definite water content (in kg or litre) in the gross mass of blowing agents. The gross mass of the blowing agents (mass of pure blowing agents plus water plus other substances) have to be measured and recorded. The mass of water shall be deducted from the gross mass of the blowing agents. The result of this calculation is the output mass of blowing agents (outBA) as base for the further calculation according to B.2.5.1 (c) and B.2.5.2 (f) of EN 50574:2012. Representative samples shall be taken i
