Conclusions:
In conclusion, the median particle size D50 of the test item was determined to be 1197 µm.
Executive summary:

In a GLP study according to OECD 110 and CIPAC MT 59 the particle size distribution of succinic anhydride has been determined. The particle size distribution was performed by sieve analysis. The results are as follows:

D10 = 377 μm

D50 = 1197 μm

D90 = 2309 μm
