ABSTRACT:
A hermetic enclosure 100 comprising a socket 155, an inlet 110 coupled to a compressor 105 via a pressure valve 115, and an outlet 130 coupled to a vacuum generator 140 via a vacuum valve 135, for over pressure testing a pressure sensitive device 10. Locating the pressure sensitive device in the socket 155 in the hermetic chamber 100, applying a predetermined pressure generated by the compressor 105 to the pressure sensitive device in the enclosure 100. Subsequently relieving the predetermined pressure and applying a predetermined vacuum generated by the vacuum generator 140 to the pressure sensitive device 10 to remove fragments of the pressure sensitive device 10, when the pressure sensitive device 10 fails the over pressure test and disintegrates.
