Description of key information

A study was performed to evaluate the particle size distribution for the test substance FAT 20004, according to the following guidelines


CIPAC MT 187: Particle Size Analysis by Laser Diffraction


ISO 13320-1: Particle Size Analysis – Laser Diffraction Methods


The Median particle size (L50) of FAT 20004 is found to be 5.77 μm. This value is also taken forward as the Mass Median Aerodynamic Diameter (MMAD).
