Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- January 02nd, 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:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- 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:
- 75 - 250 µm
- Remarks on result:
- other: 96.38 % of particles have a size higher than 75 µm
- Conclusions:
- D50: 75 - 250 µm
- Executive summary:
The dry sieve test of test item was determined as per CIPAC MT 59, “Dry Sieve test”. The dry sieve test with the test item was carried out in single replicate. The sieve with 75 µm size retained ≥ 90 % of the particles; the sieve with 750 µm size, retained ≤ 10 % of the particles.
Conclusion
D50: 75 - 250 µm
