Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
Deviations:
no
Principles of method if other than guideline:
Equipment: SYMPATEC
method: laser diffraction
test item used as received
GLP compliance:
not specified
Type of method:
Laser scattering/diffraction
Type of distribution:
volumetric distribution
Percentile:
D50
Mean:
5.5 mm
Remarks on result:
other: Pelletised form,width 5 to 6 mm, length 5 to 15 mm(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
Percentile:
D50
Mean:
5.5 mm
St. dev.:
0.5
Remarks on result:
other: Pelletised form,width 5 to 6 mm, length 5 to 15 mm

The calcuation of the standard deviation is not possible, due to the fact that only one determination was performed.

Conclusions:
The median particle size L50 of the test items deduced from the particle size distributions is 5.5 mm.
