Particle size analysis. Laser diffraction methods Ingestion-build-115288 Test methods and a recommendedWhat is ISO 13320 Laser diffraction method about? ISO 13320 provides guidance on instrument qualification and size distribution measurement of particles in many two phase systems (e. g., powders, sprays, aerosols, suspensions, emulsions, and gas bubbles in liquids) through the analysis of their light scattering properties. ISO 13320 is applicable to particle sizes ranging from approximately 0,1 m to 3 mm. With special instrumentation and conditions,
