- Scope
- This part of GB/T 26645 specifies the method for analyzing the particle size distribution of particulate materials by liquid gravity sedimentation method. The typical particle size measurement range is 0.5 μm to 100 μm. This section applies to the measurement of particle size distribution of slurries or particulate materials that can be dispersed in liquids. Normally the density difference between the dispersed and continuous phases is positive, but it can also be used to measure the size distribution of emulsion droplets which are less dense than the dispersed phase. Particles cannot undergo physical or chemical changes in suspension. Basic protective measures are required for hazardous materials, especially when volatile liquids with low boiling points are used as the continuous phase, the analyst must first conduct an explosion-proof test. NOTE: This section may contain hazardous materials, procedures, and equipment. This section does not indicate all the safety issues involved in the use process. For users, safety should be fully considered before use, understanding of operating rules, and training on operating skills.
