- Executive summary:
The particle size distribution of the test material was investigated in accordance with the standardised guidelines OECD 110, under GLP conditions.
The particle size of the test material was determined from an enlarged photograph of the particles. The particles of the test material were observed to be rod-like in shape. The particle length ranged from 0.32 – 1.27 mm with an average of 0.70 ± 0.27 mm. The particle width ranged from 0.14 – 0.36 mm with an average of 0.23 ± 0.06 mm.
Under the conditions of this study the particle size distribution D50 (median) of the test material was determined to be 0.23 mm (width) and 0.73 mm (length).
