With granulometry the particle size distribution according to DIN 66165, April 1987 for sieves with a mesh size from 63 to 1400 µm, has to be determined.

Conclusions:
Mean particle size of 63 - 1400 µm was determined for the substance using a relevant test method. The result is considered to be reliable.
