Any other information on results incl. tables
T002680 is a slightly yellow to brown, granular powder.
The fraction, which passes the 250 μm sieve, is usually used for the measurement using the laser diffraction apparatus. Only about 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.
Applicant's summary and conclusion
- Conclusions:
- T002680 is a slightly yellow to brown, granular powder. The particle size distribution of T002680 was determined by the sieving test. Only about 5% of the test item passed the 250 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.
