Bandelin® SONOREX FT 14 foil test frame

For the testing of an ultrasonic cleaner, a foil test (aluminum foil test) according to IEC 886 is recommended at initial start-up and after the corresponding operating time at regular intervals (e.g. ¼-yearly). The effect of ultrasonic baths is determined by the intensity and distribution of the process-typical cavitation in the oscillating tank. The foil test is a simple procedure to show the intensity and distribution of cavitation in an ultrasonic cleaner. For this purpose, an inserted aluminum foil is perforated or destroyed by cavitation to a certain degree, depending on the time period. The foils can be archived in a suitable way (scanning, photo, etc.). Comparison of the foils is thus possible at any time. The perforated or perforated areas of the foils should have approximately the same extension and distribution - they are never congruent. Process verification, e.g. in the reprocessing of medical devices, can only be achieved by regular foil tests. The choice of foil frame depends on the size of the ultrasonic cleaner. The wire frames are designed for a wide range of tank dimensions. For the test procedure, additional aluminum household foil is required, this is not included in the scope of delivery.
