- the grid is soaked in a 100 ml beaker containing 80 ml of the test composition maintained at room temperature, under controlled and stable ventilation.
- a timer is started which will measure the evaporation rate at the moment when the totally immersed grid is removed from the composition to be tested.
- the end of the evaporation is determined by observing the composition front which migrates over time (at the moment end of evaporation, the forehead disappears). About fifteen measurements were made and the average value of these measurements is reported in the table after ..
