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:
- Test start:16 January, 1990; Test end: 17 January, 1990; Study completion date: 31 January, 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: Sieving method
- Version / remarks:
- The test substance could not be analysed in accordance with the OECD Guideline for Testing of Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter Distributions" because its particle size distribution is
too large to be analysed by any of the suggested methods. - Deviations:
- no
- Principles of method if other than guideline:
- This test was performed by the sieving method. The measurements were performed on an "Alpine Luftstrahlsieb" using mesh sizes in accordance with DIN 4188. 0.5 to 20 g of the test substance are analysed with sieves of successively coarser mesh sizes. Sieving with each mesh size is repeated until less than 1 % change in weight of the residual substance is observed within 180 s sieving time.
- GLP compliance:
- no
- Type of method:
- sieving
- Type of particle tested:
- primary particle
- Type of distribution:
- mass based distribution
- Specific details on test material used for the study:
- SOURCE AND DETAILS OF TEST MATERIAL
- Identification: Methine Blue TRL; FAT no. 31'064/F

- Conclusions:
- The median of mass distribution (width) for the test substance was determined to be 98 μm.
- Executive summary:
A study was conducted wherein the particle size distribution of the test substance was evaluated using the seiving method. The test substance could not be analysed in accordance with the OECD Guideline for Testing of Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter Distributions" because its particle size distribution is too large to be analysed by any of the suggested methods. The test substance contains a few large particles. Depending on whether some lumps come into the sieving sample or not, the results of subsequent sittings scatter considerably. For this reason, the average of all siftings is taken as the final result. Furthermore, since the large particles are very brittle and are therefore partially destroyed during long sieving operations, the sieving procedure was based on a constant sieving time of 8 minutes. Based on the findings of the study, the median of mass distribution (width) for the test substance was determined to be 98 μm.
