Scope

This Part of GB/T 21649 describe a method for controlling the position of moving
particles in a liquid or gas and on a conveyor, as well as the image capture and image
analysis of the particles. The method is used to measure the particle sizes and their
distributions, the particles being appropriately dispersed in the liquid or gas medium or
on the conveyor.
