GB/T 25266-2010 "Paints — Determination of particle size distribution of paint fillers by Anderson pipette method" is applicable for determining the mass fraction of paint filler particles with Stokes diameters greater than 2 μm. The principle is based on the differences in sedimentation velocities of particles with varying sizes. After dispersion treatment, samples are collected at specific intervals using a 10 mL Anderson pipette, and the particle size distribution is calculated after drying and weighing. The test requires specialized instruments such as an Anderson pipette and drying equipment, providing a standardized method for controlling the particle size of paint fillers.
