The method described is meant for p

37、articulate biofuels only, namely, materials that either have been reduced in size, such as most wood fuels, or are physically in a particulate form. This part of ISO 17827 applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and below (e.g. sawdust).2 Normative referencesThe

42、 by mechanical means.NOTE Manual sieving is excluded due to the fact that small sieve holes could easily be clogged by particles.1) To be published.DIN EN ISO 17827-2:2016-10 EN ISO 17827-2:2016 (E) 5 5 Apparatus5.1 SievesFor the test, an appropriate number of either circular or rectangular sieves w

43、ith a minimum effective sieve area of 250 cm2is required. For laboratory samples with a top size below 3,15 mm, the sieves shall have an aperture geometry in accordance with ISO 3310-1 (metal wire cloth) and for test materials with a top size 3,15 mm or above, the sieves shall have round perforated

44、holes in metal plate in accordance with ISO 3310-2 (perforated metal plate). The frame of the sieves shall have a height that enables the sieves to contain the samples and allows a free movement of the sample during the sieving process.The number of sieves and the aperture sizes of the sieves shall

45、be chosen with the size specification for the actual laboratory sample material in accordance with ISO 17225-1. For sawdust and similar fine grade materials, the following set of sieves is recommended: 3,15 mm round holes; 2,8 mm metal wire cloth; 2,0 mm metal wire cloth; 1,4 mm metal wire cloth; 1,

46、0 mm metal wire cloth; 0,5 mm metal wire cloth; 0,25 mm metal wire cloth.NOTE If further classification of larger particles is required, sieves with round holes with an aperture of 4,0 mm and 5,6 mm can be applied.5.2 Collecting panFor collection of material passing through the sieves, a collecting

47、pan of adequate size is required.5.3 Weighing containersThe 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. For this purpose, an adequate numb

48、er of weighing containers are required.5.4 BrushFor cleaning the sieves, a brush is required.5.5 Mechanical sieving equipmentThe mechanical device (sieving machine) shall apply a vibration on the sieves. Some sieving machines have adjustable parameters. The results of the sieving may differ depending on how adjustable parameters are controlled. It is therefore important for comparative purposes to report how adjustable parameters h
