Abstract

The invention relates to a simplified method for detecting leaks on a non-rigid test specimen, comprising the steps of: introducing the test specimen into a film chamber, lowering the pressure in the film chamber outside of said test specimen, and detecting a leak in the test specimen on the basis of a spatial change in the film of said film chamber.
