METHOD AND MEASURING DEVICE FOR EXAMINING THE HYDROGEN PERMEABILITY OF A TEST OBJECT

摘要

The invention relates to a method for examining the hydrogen permeability of a test object (1), comprising the steps of: providing a sensor device (110) on a first side (3) of the test object (1); applying a test gas (5) containing hydrogen (2) to a second side (4) of the test object (1); and detecting hydrogen (2) penetrating the test object (1) from the second side (4) to the first side (3), using the sensor device (110), wherein the sensor device (110) comprises at least one hydrogen-absorbing sensor layer (111), and detection of the penetrating hydrogen (2) comprises sensing a state change of the at least one sensor layer (111). The invention further relates to a measuring device (100) for examining the hydrogen permeability of a test object (1).
