Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 187 (CIPAC Handbook K 2003)
- Deviations:
- no
- Principles of method if other than guideline:
- Performance of particle size analyses by test sieving in the most satisfactory conditions.
The analyser provided a graph and the percentage of particles by range of sizes. The median and the mean valuess were calculated by the analyser. The wet dispersion method was used. - GLP compliance:
- no
- Remarks:
- Methode accurately and completely described.
- Type of distribution:
- volumetric distribution
