Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
5.4.2019
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Qualifier:
no guideline followed
Principles of method if other than guideline:
Particle size/ Pellet size was manually measured using a digital caliper (Preisser, DIGI-MET, Germany). 50 pellets of the test material were randomly selected, and diameter and height measured.
GLP compliance:
no
Type of method:
other: manual measurement using a digital caliper
Specific details on test material used for the study:
Palsgaard PGMS 2202
-Id. 21055101.
-Batch 8332002.
Key result
Mean:
ca. 4.19 mm
St. dev.:
0.55
Remarks on result:
other: Pellet diameter

The measured diameter ranged from 2.4 mm to 5.38 mm with average and standard deviation (4.19 mm±0.55 mm).

The measured height ranged from 1.40 mm to 2.49 mm with average and standard deviation (1.83 mm±0.20 mm).

Conclusions:
The particle size/pellet size was manually measured using a digital clipper. 50 pellets of the test material were randomly selected, and diameter and height measured. The average diameter and standard deviation was (4.19 mm ± 0.55 mm).
Executive summary:

Particle size/ Pellet size was manually measured using a digital clipper.

50 pellets of the test material were randomly selected, and diameter and height measured.

 The measured diameter ranged from 2.4 mm to 5.38 mm with average and standard deviation (4.19 mm±0.55 mm). The measured height ranged from 1.40 mm to 2.49 mm with average and standard deviation (1.83 mm±0.20 mm).
