Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: - CIPAC (Collaborative International Pesticides Analytical Council), Physico-chemical Methods for Technical and Formulated Pesticides, MT 169.1 “Tap Density of water dispersible granules”
Principles of method if other than guideline:
No liquids were found able to wet the sample without a contemporary solvent effect.

Therefore, ChemService S.r.l. conducted a study to determine the bulk (tap) density of a sample of Amorphophallus Campanulatus Dry Purified Extract supplied by the Sponsor.

The study was performed in accordance with Study Protocol CH - 309/2009 and the following guidelines:

- CIPAC (Collaborative International Pesticides Analytical Council), Physico-chemical
Methods for Technical and Formulated Pesticides, MT 169.1 “Tap Density of water
