Describes ultrasonic methods for determining the size distributions of one or more material phases dispersed in a liquid.

This part of ISO20998 describes ultrasonic methods for determining the size distributions of one or more material phases dispersed in a liquid. Colloids, dispersions, slurries and emulsions are within the scope of this part of ISO20998. The typical particle size for such analysis ranges from 10nm to 3mm, although particles outside this range have also been successfully measured. Measurements can be made for concentrations of the dispersed phase ranging from 0,1%by volume up to 50%or more by volume, depending on the density contrast between the continuous and the dispersed phases. These methods can be used to monitor dynamic changes in the size distribution, including agglomeration or flocculation in concentrated systems.
