| Predmet normy: | This document specifies a method for the determination of the content of heavy extraneous materials (HEM) larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225-1, and especially for hogfuel in accordance with ISO 17225-9. NOTE 1 This method is designed to determine the level of impurities larger than 3,15 mm with a specific density >1 g/cm3, such as stones, 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. NOTE 3 Some heavy extraneous materials (e.g. lumps of clay) can fall apart when submerged in water. NOTE 4 Heavy extraneous materials smaller than 3,15 mm can damage milling equipment, when reducing the material in size to produce laboratory samples. |
