How do you test the performance of an antifoam?
*Shake test – antifoam test that can be easily performed in the field.
*Stirrer test – antifoam test that more accurately reflects many foaming problems during dilution and formulation of sprays.
*Air sparge test – antifoam or defoam test that allows a more quantitative measurement of performance when used with calibrated cylinders.
*Pump test – antifoam or defoam test that can simulate foaming problems during pumping.
