Applicant's summary and conclusion

Conclusions:
A range of > 2 - 5 mm covers more than 80 % of the particle size distribution of the test substance. No particles < 0.063 mm were found.
Executive summary:

Applying dry sieve analysis a range of > 2 -5 mm were determined to cover more than 80 % of the particle size distribution of the test substance. No particles < 0.063 mm were found.
