ISO 13317-4:2014 Determination of particle size distribution by gravitational liquid sedimentation methods - Part 4: Balance method

standard by International Organization for Standardization, 11/15/2014

Full Description

ISO 13317-4:2014 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 number less than 0,25 is satisfied.
