Method for performing a leak test on a test object

For leak testing, a tracer gas is advanced to the outer wall (11) of the hollow test object (10) while the test object (10) is in an evacuated state. The tracer gas is discharged from a blower device (14) in the form of soap bubbles (21). When contacting the outer wall (11), the soap bubbles will bu...

Summary:For leak testing, a tracer gas is advanced to the outer wall (11) of the hollow test object (10) while the test object (10) is in an evacuated state. The tracer gas is discharged from a blower device (14) in the form of soap bubbles (21). When contacting the outer wall (11), the soap bubbles will burst, thus forming a cloud (27) of tracer gas immediately on the outer wall (11). By the invention, it is made easier to localize the invisible tracer gas in the ambient air. Further, the tracer gas can be used more effectively so that the costs for performing the testing process are reduced.
