The invention relates to a test disc system having at least one test disc for testing the seal of a glove which is installed in a port of an insulator. The test disc (1) can be connected in a hermetically sealed fashion to the port, wherein the glove encloses with the test disc (1) a glove volume which can be placed under overpressure by the test disc (1). The test disc (1) has a base body in which electronic components for recording and storing a pressure profile in the glove volume, and at least one data interface are arranged. The test disc (1) also has a reading device for reading both a first identification element which is arranged on the glove and a second identification element which is assigned to the port.
