DIN EN 15415-1:2011-11 EN 15415-1:2011 (E) 4 1 Scope This European Standard specifies the determination of particle size distribution of solid recovered fuels by a machine or manual sieving method. It applies to particulate agglomerated and non-agglomerate

23、d fuels, such as fluff, pellets, briquettes, pulverised solid recovered fuels. This sieving method is not applicable to large pieces with irregular shape such as the pieces of shredded tyres or of demolition wood. In the case, of large pieces of irregular shape, prEN 15415-2 and prEN 15415-3 are app

24、licable. NOTE 1 For fine particles 3,15 mm, it is recommended to use sieves with hole diameters of 3,15 mm, 6,3 mm, 12,5 mm, 25 mm, 50 mm, 100 mm and 125 mm, and for solid recovered fuels 125 Manual sorting 100 to 125 1stsieve (50 mm) 50 to 100 2ndsieve (25 mm) 25 to 50 3rdsieve (12,5 mm) 12,5 to 25

25、 4thsieve (6,3 mm) 6,3 to 12,5 5thsieve (3,15 mm) 3,15 to 6,3 Collecting pan 125 mm) Number of overlong (100 mm to 125 mm) Length of longest particle overall, in millimetres (if required) Difference between the total mass of test portion and the total mass of all fractions (column 4), in percent of

26、the total test portion Moisture content of the sample, in percent Raw or air-dried sieving Manual or machine sieving Metal wire cloth or perforated metal plate Trade form (e.g. fluff, pellets, briquettes) NOTE 1 For smaller sieves, it can be convenient to combine two or more sieves in the same sievi

27、ng operation. Ensure that the sieves (particularly the lower sieves) do not clog because of a too great mass on the upper sieve. If a sieve is mostly or entirely clogged, decrease the mass of the sub-samples such that there is no clogging on any sieves and repeat the test. NOTE 2 In many cases, it i

28、s useful to identify the greatest particle (maximum dimension) and record it in a scheme according to Table 1. The information on the longest particle can be required for computing the median particle size or for illustrating the results in a cumulative size distribution curve. DIN EN 15415-1:2011-1

29、1 EN 15415-1:2011 (E) 9 When classifying size by sieving, some of the thin particles longer than the hole diameter will pass through the sieve and mix with the particles in the smaller size fractions. Most of these particles remain in that fraction. Only particles greater than 100 mm (maximum dimens

30、ion) shall be manually sorted as specified above. 7.3 Mechanical sieving Assemble and operate the mechanical shaking device with the appropriate sieve sizes with decreasing aperture size ending with the collecting pan. Weigh the sample to the nearest 0,1 g. Spread the sample (sub-sample) in an even

31、layer on the top sieve and start the sieving operation. Weigh the retained net material on each sieve and in the collecting pan to the nearest of 0,1 g. In the case that a particle sticks in a sieving hole, it shall be removed and added to the fraction, which has remained on the sieve (as if it did

32、not pass the hole). All particles greater than 100 mm (maximum dimension) shall be manually classified into one or more fractions regardless of which sieve or collecting pan they are collected in. In this case, the size is defined as maximum length of the particle. Record the mass of each fraction i

33、n a scheme according to Table 1. Ensure that the sieves (particularly the lower sieves) do not clog because of a too great mass on the upper sieve. If a sieve is mostly or entirely clogged, decrease the mass of the sub-samples such that there is no clogging on any sieves and repeat the test. When cl

34、assifying size by sieving, some of the thin particles longer than the hole diameter will pass through the sieve and mix with the particles in the smaller size fractions. Most of these particles will remain in that fraction. Only particles greater than 100 mm (maximum dimension) shall be manually sor

35、ted as specified above. NOTE 1 In many cases, it is useful to identify the largest particle (maximum dimension) and record it in a scheme according to Table 1. The information on the longest particle can be required for computing the median particle size or for illustrating the results in a cumulati

36、ve size distribution curve. NOTE 2 During the sieving operation, particularly fine particles can stick to the edge of the sieves due to static electricity. Since this problem is mostly connected to the intensity of the mechanical shaking operation, it should be taken into consideration in a separate

37、 pre-test for each equipment and solid recovered fuel sample materials. Grounding the sieves using a copper wire can reduce the problem with static electricity. 8 Calculation of results The results shall be expressed as a percentage of the total mass of all fractions. If more than one sample (sub-sa

38、mple) is processed, the mass of the respective fractions shall be added up before calculating the overall percentage of each class. An example of this procedure is shown in Table 1. The difference between the total mass of test portion and the total mass of all fractions shall be less than 2 %. Larg

39、er differences can occur due to lost or retained particles or due to changes in moisture content. In this case, the causes for the deviation shall be investigated and the measurement repeated. In case this is impossible or the result still deviates more than accepted, this shall be reported. 9 Preci

40、sion Because of the varying nature of solid recovered fuels covered by this document, it is not possible at the present time to give a precision statement (repeatability or reproducibility) for this test method. DIN EN 15415-1:2011-11 EN 15415-1:2011 (E) 10 10 Test report The test report shall inclu

41、de at least the following information: a) name of the testing establishment; b) date of the test; c) a reference to this European Standard, i.e. EN 15415-1; d) identification of the product or sample tested; e) test results as shown in Table 1; f) if the difference of 2 % between the total mass of t

42、est portion and the total mass of all fractions, in percent, of the total test portion according to Table 1, column (4), has been exceeded, it shall be clearly stated and, if necessary, founded why the test has not been repeated; g) any deviation from this European Standard; h) any unusual features

43、observed during the determination which may affect the result and details of any operations not included in this European Standard or regarded as optional.
