To document the test results, you can download a
documentation template here:

Here you will also find an application video.
Foils can also be archived if done in a suitable
manner (scanning, photos, etc.). This allows foils to be compared at
any time.
Conducting the foil test
1. Fill the oscillating tank to the filling level mark with water and a
suitable ultrasound preparation, in the concentration specified
by the manufacturer.
2. Degas the sonication liquid.
See chapter 5.7 Degassing sonication fluid .
3. Stretch aluminium foil (house-
hold foil, 10 μ m to 25 μ m thick)
over the foil test frame.
Depending on the tank size, it is
possible that the frame will pro-
trude outside the tank. Covering
the part of the foil test frame
that is covered by the sonication
liquid will be enough.
4. Place the covered foil test frame diagonally
in the centre of the oscillating tank. Fasten
it if necessary.
5. Switch on the ultrasound. Sonicate the foil
for at least one minute until visible perfora-
tions or holes are produced. With sturdier
foils (thicker or coated ones), the sonication
time may be up to 3 minutes.
6. Switch off the ultrasound. Remove the foil test frame. Remove
the aluminium foil from the foil test frame and allow it to dry.
