- Adequacy of study:
- key study
- Study period:
- March 20, 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 59 (Dry Sieve test)
- Deviations:

- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Specific details on test material used for the study:
- The test item was used in its initial form, without any pre-treatment.
- Percentile:
- D50
- Mean:
- 150 - 210 µm
- Remarks on result:
- other: sieve test
- Conclusions:
- D50: between 150 - 210 µm
- Executive summary:
The particle size distribution of the test item was determined as per CIPAC MT 59, “Dry Sieve test”.
The dry sieve test was carried out in single replicate. The sieve with 45 µm size retained more than 90 % of the particles; the sieve with 710 µm size, retained less than 10 % of the particles. The D50 was recorded between 150 - 210 µm.
Conclusion
D50: between 150 - 210 µm
