METAL SHARK® Teststicks
Calibrated test specimens for metal detectorsWith the help of a metallic test ball of a defined size, the function of the metal detector can be tested in operation. A test ball is added to the product and is subsequently passed through the metal detector. If the detector recognises the ball, the test is considered passed.
shark_testball_e.pdfThe test intervals shall be short enough: All products having passed the metal detector since the last test procedure must be still available to be re-tested once again. In addition, tests should be carried out at the beginning of working shift and when changing products.
Daily Metal Detector Record
It is recommended to regularly test the metal detector with standardized test objects and to keep records of these tests in a daily metal detector record. Metal testing spheres are generally supplied along with the detector.
A suitable metal testing object and a testing schedule should be established for the examination: The testing object should be a sphere of the smallest diameter which detection is required. The sphere is passed through the detector along with the product in order to observe whether a metal detection signal is issued.
The testing schedule should establish when the detector is to be tested and by whom. Example: The quality manager on duty has to test the detector using the testing object one hour after the start of each shift. The test results are recorded in the record with the date, time and signature. Example: Test object recognised, 24 August 2001, 08.30, signed, Smith.
