This document specifies methods for sample preparation to determine the size distribution of separate particles of a single pigment or extender, which is or is to be dispersed in a liquid by application of a standardized dispersion procedure using an ultrasonic device or a shaker device or a wet jet mill. The described sample preparation methods are optimized for measurements carried out with a particle sizing technique based on sedimentation. This technique relies on particle migration due to gravitation or centrifugal forces and requires a density contrast between the particles and the liquid phase.
