Measurement and characterization of particles by acoustic methods - Guidelines for linear theory Ingestion-build-205840

Measurement and characterization of particles by acoustic methods - Guidelines for linear theory Ingestion-build-2058401 Scope This part of ISO 20998 describes ultrasonic attenuation spectroscopy methods for determining the size distributions of a particulate phase dispersed in a liquid at dilute concentrations, where the ultrasonic attenuation spectrum is a linear function of the particle volume fraction. In this regime, particleparticle interactions are negligible. Colloids, dilute dispersions, and emulsions are within the scope of this part of ISO 20998. The
