Scope: This part provides guidance for measuring the particle size distribution of any two-phase system by analyzing the angular light scattering diagram of the particle. These two-phase systems include: powders, water mist, aerosols, suspensions, emulsions, and bubbles in liquids, etc. . This standard does not put forward specific requirements for the particle size measurement of specific products, and can be used to measure particles with a particle size ranging from 0.1 um to 3 mm. For non-spherical particles, since this technique assumes that the particles in its optical model are spherical, an equivalent spherical particle size distribution can be obtained. The result of this particle size distribution may differ from that obtained by measurement methods based on other physical principles (eg sedimentation, sieving).
