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
