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
- Study period:
- September 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- - Principle of test: The particle size distribution of the material was measured using sieve shaker and standard 200 mm diameter sieves. A sample of the material was weighed onto the sieves and shaken intermittently (8 seconds on / 4 seconds off) for 30 minutes.
- Parameters analysed / observed: The resultant fractions were weighed to determine the particle size distribution. - GLP compliance:
- no
- Type of method:
- sieving
- Type of distribution:
- mass based distribution
- Key result
- Percentile:
- D50
- Mean:
- > 500 - < 1 000 µm
- Remarks on result:
- other: Standard deviation not calculated

- Size:
- > 125 µm
- Distribution:
- 36.4 %
- No.:

- Size:
- > 90 µm
- Distribution:
- 0.1 %
- No.:
- #7
- Size:
- > 63 µm
- Distribution:
- 0.3 %
- No.:
- #8
- Size:
- > 38 µm
- Distribution:
- 0.5 %
- Conclusions:
- The median particle size of the sample of glutaric acid was 500 to 1000μm.
- Executive summary:
The particle size distribution of the material was measured using sieve shaker and standard 200 mm diameter sieves. A sample of the material was weighed onto the sieves and shaken intermittently (8 seconds on / 4 seconds off) for 30 minutes. The resultant fractions were weighed to determine the particle size distribution. The median particle size of the sample of glutaric acid was found to be 500 to 1000μm.

Description of key information
The particle size distribution of the substance was measured using sieve shaker and standard 200 mm diameter sieves. The resultant fractions were weighed to determine the particle size distribution. The median particle size of the sample of glutaric acid was found to be 500 to 1000μm.
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.
