Application Summary AI generated
This standard specifies the photocentrifuge method for determining particle size distribution in liquid suspensions, where sedimentation is accelerated by centrifugal force and particle concentration is monitored optically. It is applied in industries such as pharmaceuticals, pigments, ceramics, and fine chemicals for quality control and research, particularly for analyzing submicron to micron-sized particles in stable dispersions. The method is used in laboratory testing contexts where precise, repeatable particle size data is required for product development or compliance with material specifications.
