Determination of particle size distribution by centrifugal liquid sedimentation methods - Photocentrifuge method PAS 15 Simplified representation of centre holes1 Scope 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 conversion to a particle size distribution. The method of determining the particle size distribution described in this part of ISO 13318 is applicable to powders that can be dispersed
