TIC2782 (T002907) is a white crystalline powder.

The fraction, which passes the 250 μm sieve, is usually used for the measurement using the laser diffraction apparatus. Only about 12.5 % of the test item passed the 250 μm sieve. This amount of test item is insignificant for the evaluation of the particle size distribution.

Conclusions:
T002907 is a white crystalline powder. The particle size distribution of T002907 was determined by the sieving test (following European Commission Guidelines). Only about 12.5% of the test item passed the 125 µm sieve. This amount of the test item is insignificant for the evaluation of the particle size distribution. The results of the study can be considered reliable without restriction.
