- Executive summary:
The determination of the particle size distribution of FAT 45176/A was performed under GLP compliance according to OECD 110 guideline. The substance FAT45'176/A is a powder with a rate of 0.55 mass-% greater than 200 µm. The particle size distribution further has been determined to be 9.9 % < 10 µm. 50 mass-% of the substance were smaller than 47 µm (MMD). The maximum of mass frequency was a about 15 µm.
