ASTM D6941
Fluidization Segregation Tester
Provides a controlled fluidization environment to assess how differences in particle size, density, shape and aerodynamic behaviour produce separation within a powder bed. Section-wise samples reveal stratification and determine the Fluidization Segregation Index.
