Description of key information
Determination of the Particle Size Distribution FAT 20044/C TE was carried out according to CIPAC MT 187 (Particle Size Analysis by Laser Diffraction) and ISO 13320-1 (Particle Size Analysis – Laser Diffraction Methods). Based on the study results, the median particle size (L50D) of FAT 20044/C is 79.392 μm. This value is also taken forward as the Mass Median Aerodynamic Diameter (MMAD).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
