Conducting the foil test
1. Fill oscillating tank to the filling level mark with water
and an appropriate ultrasonic agent, in the concentration
specified by the manufacturer.
2. Degas the liquid (see user instructions)
3. Stretch aluminium foil (household foil, 10
v
m to 25
v
m
thick) over the foil testing frame.
Depending on the tank size, it is possible that the frame
will protrude outside the tank.
It is sufficient to cover the submerged portion of the
frame with foil.

5. Switch on the ultrasound and sonicate the foil for at least
one minute until visible perforations 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, take the foil out
and let it dry.
7. The foil must be perforated,
see photo. Otherwise, we
recommend having the
device checked by the service
department at BANDELIN
electronic GmbH & Co. KG.
8. Archiving of foil with test date
and serial number of the ultrasonic bath. The foil test
document template can also be completed and archived.
9. After the test, the oscillating tank must be thoroughly
rinsed out to remove any loose foil particles.
