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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- The particle size distribution was performed by weighing sieves with defined mesh numbers before and after the sieving process.
- GLP compliance:
- not specified
- Type of method:
- sieving
- Type of particle tested:
- aggregate
- Type of distribution:
- mass based distribution
- Key result
- Percentile:
- D50
- Mean:
- ca. 125 - ca. 250 µm
- Remarks on result:
- other: The median particle size is for the substance as received
- Percentile:
- D50
- Mean:
- ca. 63 - ca. 90 µm
- Remarks on result:
- other: The median particle size is for the substance as milled
- Conclusions:
- Median particle size of 125 - 250 µm was determined for the substance as received, which is relevant for the substance as placed on the market, using a relevant test method. The result is considered to be reliable.

Description of key information
Granulometry: Median particle size: 125 - 250 µm (sieve method)
Additional information
A median particle size in the range of 125 - 250 µm is using a sieve method is determined for the submission substance as received, which is relevant for the substance as placed on the market. The result is considered to be reliable.
