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:
- 2019-03-28 - 2019-03-28
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius)
- Version / remarks:
- OECD Guideline 110 (1981): Particle size distribution
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Version / remarks:
- ISO 13320 (2009): Particle size analysis - Laser diffraction methods
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Percentile:
- D10
- Mean:
- 222 µm
- St. dev.:
- 9.28
- Key result
- Percentile:
- D50
- Mean:
- 502 µm
- St. dev.:
- 1.99
- Percentile:
- D90
- Mean:
- 907 µm
- St. dev.:
- 4.18
- Conclusions:
- The study was conducted under GLP according to OECD TG 110 and ISO 13320 without deviations and therefore reliability of Klimisch 1 has been assigned. Based on the obtained results the test item Magnesium perchlorate has a median particle size of D50 = 502 µm.
- Executive summary:
The test item Magnesium perchlorate has a median particle size of D50 = 502 µm, which was determined by laser diffraction measurement according to OECD Test Guideline 110 (1981) and ISO 13320 (2009).
