Abstract
Systems and methods for verifying sealing integrity in a portable electronic device. One method includes raising, with an electronic processor, an internal temperature of the portable electronic device. The method includes, when the internal temperature exceeds a threshold, determining whether a vent port of the portable electronic device is closed. The method includes, when the vent port is closed, receiving, from a pressure sensor, a first internal pressure for the portable electronic device. The method includes, after a cool down period has elapsed, receiving, from the pressure sensor, a second internal pressure for the portable electronic device. The method includes determining, based on the first and second internal pressures, a pressure drop rate. The method includes determining a sealing integrity indication based on the pressure drop rate. The method includes providing a test result output based on the sealing integrity indication.
