标准范围
This document specifies a method for the determination of content of heavy extraneous materials
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 17225-1:2014, 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/cm3 such as stones, glass, rubber, metal and certain types of lastics.
NOTE 2 During the processing of the sample, hand sorting of light impurities with a specific density ≤1 g/cm 3(e.g. plastic foil) can also be done.
