Characterization of bulk materials - Determination of a size-weighted fine fraction and crystalline silica content - Part 3: Sedimentation method; German version EN 17289-3:2020


The purpose of this document is to allow users to determine a sizeweightedfine fraction by the sedimentation method. The method in this part uses a liquid sedimentation technique to separate the fine fraction, which is then analysed for its substance of interest, e.g. crystalline silica. Informative annexes within this document describe specific methods for the evaluation of FF forspecific bulk materials.This document is applicable for bulk materials that contain particles in the size range from 0,1 micrometer to 125 micrometer satisfying with the criteria given in this part and Part 2 of the document series.
