GB/T 26645.4-2018 "Particle size analysis - Liquid gravitational sedimentation method - Part 4: Balance method": This standard is part of the series of standards for particle size analysis using the liquid gravitational sedimentation method, and specifies a method for analyzing particle size distribution by weighing the mass of particles settled by gravity in a liquid. The method determines the particle size distribution of equivalent spherical diameters by directly measuring particle mass, and is applicable to typical sample particle sizes ranging from 1 μm to 100 μm, with the condition that the Reynolds number does not exceed 0.25. It provides a standardized testing approach for particle size analysis of relevant particulate materials.
