Measurement and characterization of particles by acoustic methods - Concepts and procedures in ultrasonic attenuation spectroscopy Ingestion-build-111333 Annex N gives an assessment1 Scope This part of ISO 20998 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 ISO 20998. The typical particle size for such analysis ranges from 10 nm to 3 mm, although particles outside this range have also been successfully measured. Measurements can be made for concentrations of the dispersed
