For testing an ultrasonic cleaner, a foil test (aluminum foil test) according to IEC 886 is recommended at initial startup and regularly (e.g., quarterly) after a corresponding operating time. The effectiveness of ultrasonic baths is determined by the intensity and distribution of the process-specific cavitation in the oscillation tank. The foil test is a simple method for representing the intensity and distribution of cavitation in an ultrasonic cleaner. An inserted aluminum foil is perforated or destroyed by cavitation up to a certain degree depending on the duration. The foils can be archived in a suitable manner (scanning, photo, etc.). The comparison of the foils is thus always possible. The perforated or punctured areas of the foils should have approximately the same extent and distribution – they are never identical. Only through regular foil tests is a process verification, e.g., in the preparation of medical devices, achievable. The selection of the foil test frame depends on the size of the ultrasonic cleaner. The wire frames are designed for a wide range of tank dimensions. For the test execution, aluminum household foil is additionally required, which is not included in the delivery.
