GB/T 26645.4-2018 is part of the series of standards for particle size analysis, focusing on the Balance method in the liquid gravity sedimentation method. It details the method of using Balance measurement to determine the particle size distribution of particles in liquids due to gravity sedimentation. Starting from the measurement principle, the required instruments such as Balance accuracy requirements are specified, the preparation process of the sample in the liquid is standardized, and the test steps and the presentation of the particle size distribution results are clarified. It provides standardized and actionable guidance for accurate particle size analysis.
