This part of ISO 13318 covers methods for determining the particle size distribution of particulate materials by means of centrifugal sedimentation in a liquid.Solids concentrations are determined by the transmission of a light beam.The resulting signal enables converison to a particle size dustribution.The method of determining the particle size distribution described in this part of ISO 13318 is applicable to powders that can be dispersed in liquids,powders that are present in slurry form and some emulsions.Typical paticle size range for analysis is from about 0,1μm to 5μm. The method is applicalbe to powders in which all particles have the same density and comparable shapes and do not undergo chemical or physical change in the suspension liquid.It is usually necessary that the particles have a density higher than that of the liqud.
