36、the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, e.g. wood chips, hog fuel, olive stones, etc. The method is intended to characterize material up to a particle size class of P63. For larger P-classes, the character

37、ization is mainly done by hand sorting.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

43、 either circular or rectangular sieves with a minimum effective sieve area of 1 200 cm2is required for the test.The sieves shall have round perforated holes in metal plate in accordance with ISO 3310-2. The frame of the sieves shall have a height that will enable the sieves to contain the sample and

44、 allows a free movement of the sample during the sieving process.The number of sieves and the aperture sizes of the sieves shall be chosen in accordance with the size specification for the actual test sample material (see also ISO 17225-1).NOTE 1 For laboratory samples with a nominal top size of les

45、s than 10 mm, an effective sieve area of less than 1 200 cm2is adequate.NOTE 2 For laboratory samples such as wood chips, the following set of sieves may be selected: 3,15 mm; 8,0 mm; 16 mm; 31,5 mm; 45 mm; 63 mm. If no particles are caught by the larger sieves, these can be omitted from the set. Fo

46、r further size distribution determination of the fraction passing through the 3,15 mm sieve, see ISO 17827-2.NOTE 3 Sieve sizes above 63 mm are not useful since the oscillation might not force the particles to orientate perpendicular to the plane of the sieves. Furthermore, the distance to the sieve

47、 below will have to be longer than the usual 80 mm in order to allow the long and slim particles to pass through the holes.For checking compliance with particle size specification in ISO 17225-1, only those sieve sizes which have limit values are required.5.2 Collecting pan, a collecting pan of adeq

48、uate size is required for collection of material passing through the sieves.5.3 Weighing containers, an adequate number of weighing containers are required.The weighing of the sieved particle fractions can be performed either by weighing the remaining material directly on the tarred weighed sieves or by collecting and weighing the material in weighing containers. 5.4 Mechanical sieving equipmentThe sieving operation shall be horizontally
