GB/T 14563-2020 specifies the product classification, physicochemical requirements, test methods, and inspection rules for kaolin. It applies to various types of kaolin and calcined kaolin used in the papermaking, enamel, rubber and plastics, ceramics, and coatings industries. The testing indicators include whiteness, particle size distribution, aluminum oxide (Al₂O₃) content, among others. Instruments such as ultrasonic dispersion equipment, sedimentation bottles, centrifugal particle size analyzers, and light scattering particle size analyzers are used for testing. For particle size determination, the sedimentation method (arbitration method) and the instrumental method (alternative method) are employed.
