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:
- 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 59 Sieve Analysis; CIPAC MT 170 Dry Sieve Analysis of Water Dispersible Granules; CIPAC MT 169 Tap Density of Water Dispersible Granules
- Deviations:
- no
- Principles of method if other than guideline:
- Sieve analysis consisting of the quantitative separation of the test item into fractions of different particle size ranges by using of machine sieving method.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Remarks on result:
- not determinable because of methodological limitations
- Key result
- Percentile:
- D10
- Mean:
- 250 µm
- Remarks on result:
- other: Not the D10, but the sieve size (µm) which passes less than 10 % of the charged substance is presented.
- Key result
- Percentile:
- D90
- Mean:
- 2 000 µm
- Remarks on result:
- other: Not the D90, but the sieve size (µm) which passes more than 90 % of the charged substance is presented.
- Conclusions:
- The sieve size (µm) which passes less than 10 % of the charged substance is 250 µm.
The sieve size (µm) which passes more than 90 % of the charged substance is 2000µm
The mean particle size (by mass) is between 500µm and 1000 µm.
No particles below 100 µm. - Executive summary:
Machine sieving test was carried out using the following test sieves 4, 2, 1 mm, 500, 250, 100, 63 and 45 μm.
The sieve size (µm) which passes less than 10 % of the charged substance is 250 µm.
The sieve size (µm) which passes more than 90 % of the charged substance is 2000µm
The mean particle size (by mass) is between 500µm and 1000 µm.
No particles below 100 µm.

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.
