ABSTRACT:
An apparatus for testing electronic devices in hostile media includes an isolation tank (24) which contains an inert or relatively inert material (26) such as fluorinated hydrocarbon liquid. Within the isolation tank (24) submersed in the inert or relatively inert material (26), is at least one test chamber (12) containing hostile and/or volatile test medium (14) such as a fuel mixture. Adjacent to the test chamber (12) and also within isolation tank (24) is a loading chamber (30) via which electronic devices to be tested are coupled to the test tank (12). The loading chamber (30), test tank (12) and isolation tank (24) are all isolated from the ambient environment and are oxygen free because they each contain a gas purge lines (33,35,38) providing an inert or relatively inert gas to a positive pressure within the respective tanks and chamber. The electronic devices (16) are electrically connected through a lid over the loading chamber (30) to computer control equipment (50) which provides for functional in situ testing.
