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:
- other: acceptable company statement
- Qualifier:
- no guideline followed
- Version / remarks:

- no
- Type of method:
- sieving
- Type of particle tested:
- other: not specified
- Type of distribution:
- counted distribution
- Specific details on test material used for the study:

>500µm: 3% - Executive summary:
The particle size distribution of the test substance was determined in a non-GLP study (2016) by using the dry sieve test.
Results:
Particle size µm % > 500 3 300 - 500 12 212 - 300 20 125 - 212 40 < 125 25

Description of key information
The particle size distribution of the test substance was determined in a non-GLP study (2012) by using the dry sieve test (< 125 µM: 25 %; 125 -212 µM: 40 %; 212 -300 µM: 20%; 300 - 500 µM: 12 %; > 500 µM: 3 %)
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
