Particle size distribution (Granulometry)
Administrative data
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 OCT 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 13320 (2009) and OECD Guideline 110 (1981)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Remarks:
- The test item is fed to the measuring cell by pressurized air (2.0 barg). The concentration in the air flow is adjusted by the opening of the cell (6 mm). The optical concentration in the measuring cell was adjusted to 3-4%.
- Type of particle tested:
- primary particle
- Remarks:
- A powder dispersing cell was used and a sieve which prevents that agglomerates are fed to the measuring cell.
- Type of distribution:
- mass based distribution
Test material
- Reference substance name:
- Disodium 1,5-dihydroxypentane-1,5-disulphonate

- IUPAC Name:
- Disodium 1,5-dihydroxypentane-1,5-disulphonate
- Reference substance name:
- Sodium sulfate
- Cas Number:
- 7757-82-6
- IUPAC Name:
- Sodium sulfate
- Reference substance name:
- Sodium hydrogen sulfite

- Remarks:
- From the measured diffraction pattern the particle size distribution is calculated. From the cumulative distribution the characteristic values: D10: 10 Vol.-% of the particles have a smaller diameter D50: 50 Vol.-% of the particles have a smaller diameter (median diameter) D90: 90 Vol.-% of the particles have a smaller diameter are derived.
