Determination of particle size distribution by gravitational liquid sedimentation methods - Balance method Ingestion-build-209418 BS EN 15221-7:2012 Facility management1 Scope This part of ISO 13317 specifies the method for the determination of particle size distribution by the mass of particles settling under gravity in liquid. This method is based on a direct mass measurement and gives the mass distribution of equivalent spherical particle diameter. Typically, the gravitational liquid sedimentation method applies to samples in the 1 m to 100 m size range and where the sedimentation condition for particle Reynolds
