For the testing of an ultrasonic cleaner, a foil test (aluminium foil test) according to IEC 886 is recommended at the initial start-up and after an appropriate period of operation regularly (e.g. ¼ annually). The effect of ultrasonic baths is determined by the intensity and the distribution of the cavitation typical for the process in the ultrasonic bath. The foil test is a simple method for displaying the intensity and distribution of cavitation in an ultrasonic cleaner. For this purpose, an inserted aluminium foil is perforated or destroyed to a certain degree by cavitation, depending on the duration.

The foils can be archived in a suitable way (scanning, photo, etc.). The comparison of the foils is thus possible at any time. The perforated or perforated surfaces of the foils should have approximately the same extension and distribution - they are never congruent. Only by means of regular film tests is it possible to check the process, e.g. during the reprocessing of medical devices.
The selection of the film depends on the size of the ultrasonic cleaner. The wire frames are designed for a wide range of bath dimensions. Aluminium household foil is additionally required for the test procedure, this is not included in the scope of delivery. Internal dimensions l × w × d: 470 x 360 x mm
