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 to july 2008
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- other: paricle size distribution
- Percentile:
- D50
- Mean:
- ca. 1 mm
- Remarks on result:
- other: Only a single mesurement was done, so the standard deviation can not be calculated.
- Percentile:
- D95
- Mean:
- > 2.8 mm
- Remarks on result:
- other: Only a single mesurement was done, so the standard deviation can not be calculated.
- No.:
- #1
- Size:
- >= 2.8 - <= 4 mm
- Distribution:
- ca. 96.1 %
- No.:
- #2
- Size:
- >= 2 - <= 2.8 mm
- Distribution:
- ca. 3.2 %
- No.:
- #3
- Size:
- >= 1.4 - <= 2 mm
- Distribution:
- ca. 0.1 %
- Conclusions:
- the majority of the particles (96.1%) was situated between 2.8 mm and 4 mm
- Executive summary:
A preliminary mechanical and manual sieving was performed using a 4 mm, 1 mm,
and 100 μm test sieves. The majority of the particles was situated between 1 and 4 mm.
Therefore, the principal sieving was made between 1 and 4 mm.
Then, a main test was performed :
Test sieve
2.8 mm
2.0 mm
1.4 mm
Collecting pan
Percentage of

The majority of the particles (96.1%) was situated between 2.8 mm and 4 mm.
Reference
the majority of the particles (96.1%) was situated between 2.8 mm and 4 mm
Description of key information
The majority of the particles (96.1%) was situated between 2.8 mm and 4 mm (OECD 110)
