Stones a

38、nd other impurities contained in biomass from stumps, roots, mill residue and harvest and landscape management residues may cause problems during size reduction, as well as during combustion.Impurities smaller than 3,15 mm are not considered as part of this testing method but may still contribute to

ISO 2017 All rights reserved vBS EN ISO 19743:2017BS EN ISO 19743:2017Solid biofuels Determination of content of heavy extraneous materials larger than 3,15 mm1 ScopeThis document specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm

40、by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225-1:2014, Table 1.NOTE 1 This method is designed to determine the level of impurities larger than 3,15 mm top size with a specific density 1 g/cm3such as stones,

41、 glass, rubber, metal and certain types of plastics.NOTE 2 During the processing of the sample, hand sorting of light impurities with a specific density 1 g/cm3(e.g. plastic foil) can also be done.2 Normative referencesThe following documents are referred to in the text in such a way that some or al

48、nk-and-float separation combined with elutriation in water. The content of heavy extraneous materials is calculated by dividing the dry weight of the obtained material by the dry weight of the original sample and is thus expressed as a percentage on dry weight basis.5 Apparatus5.1 Water container.Th

The height-diameter-ratio shall be within 1,0 and 1,3. The container shall have a circular bottom to enable the free movement of the particles in the flow of water when stirred. The container shall be cylindrical or with conical sidewalls with a maximum inclination of 15 to facilitate the overflow of the bioma
