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:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 170 (1994) Dry Sieve Analysis of Water Dispersive Granules
- Principles of method if other than guideline:
- The sieve analysis consists of the quantitative separation of water dispersible granules into fractions of different particle size ranges by using a hand sieving method.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: dry sieve analysis
- Type of particle tested:
- primary particle
- Type of distribution:
- other: mass distribution: hand sieving
- Percentile:
- other: D97
- Mean:
- ca. 125 µm
- Remarks on result:

- No.:
- #1
- Size:
- 11 µm
- Distribution:
- 100 %
- Conclusions:
- More than 80 % of the test item was found to be bigger than 125 μm. No particles with a diameter below 11 μm were found.
As only residues > 90% were determined, the range of the sieves with 10% < Rx < 90% could not be determined.
No observations were made which have cause doubts concerning the validity of the study outcome. - Executive summary:
The particle size distribution of Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc was performed according to CIPAC MT 170. Six sieves of different mesh sizes were used. Based on dry sieve analysis of the test item Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc, more than 80 % of the test item was found to be bigger than 125 μm. No particles with a diameter below 11 μm were found. As only residues > 90% were determined, the range of the sieves with 10% < Rx < 90% could not be determined. No observations were made which have cause doubts concerning the validity of the study outcome.
Reference
Distribution = Residue (% m/m)
The tap density (according to CIPAC MT 169) of Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc was determined as 0.83 g/mL ( = g/cm3).
The mass of the sample needed for the main test (m) was calculated to 99.6 g (16.6 g/sieve).
The particle size distribution of the test item was specified by the range [x1, x2] of two sieves, Rx >= 90 % and Rx <= 10 % is estimated. This range covers 80% or more of the particle size of the test item.
