Particle size distribution (Granulometry)
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:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: internal certified procedure N° STR 071ed. 1
- Version / remarks:
- internal certified procedure N° STR 071ed. 1
- Deviations:
- no
- Principles of method if other than guideline:
- About 10g of sample were sieved with 500um pore sieve. The lower fraction was weighted to assess its percentage on the whole, and the lower fraction was analysed by laser method for particle size distribution.
Particle size was assessed by laser diffraction technique using an instrument Malvern Mastersizer 2000 dispersing the sample in silicon oil Tegiloxan - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- <= 26.229 µm
- St. dev.:
- 0
- Percentile:
- D50
- Mean:
- <= 80.945 µm
- St. dev.:
- 0
- Percentile:
- D90
- Mean:
- <= 149.66 µm
- St. dev.:
- 0
- Conclusions:
- Particle size distribution is:
Fraction 0.2: 26.3um
Fraction 0.5: 80.9um
Fraction 0.9: 149.7um - Executive summary:
Particle size distribution was assesed by laser diffraction technique.
Particle size distribution is:
Fraction 0.2: 26.3um
Fraction 0.5: 80.9um
Fraction 0.9: 149.7um
Reference
The average particle size is.
D10 ≤ 26.229 µm
D50 ≤ 80.945 µm
D90 ≤ 149.66 µm
