Analytical monitoring:
yes

Test solutions

Vehicle:
yes
Details on test solutions:
The carrier is DMF (Dimethylformamide) 0.93, 1.88, 3.75, 7.5, 15 mg test item/L. Additionnaly, a solvent control (100 mg DMF/L) and a control (test water without addition of the test item ) were tested on parallel.
All analytically determined test concentrations remained within 80 - 120% of nominal values. Results are presented based on nominal test concentrations.
