The particle size distribution was found to be 125 μm - 500 μm.

Conclusions:
The particle size distribution was found to be 125 μm - 500 μm. Less than 10% are <= 63 μm.
Executive summary:

The study was performed according to CIPAC methods MT 169 & 170, using the sieving method. The particle size distribution of the test item was found to be 125 - 500 μm. Less than 10% are <= 63 μm.
