Abstract
A method for testing a container (11) having an interior volume (12) for tightness, comprising the following steps: providing the container (11) in a pressure chamber (10) and reducing pressure within the pressure chamber (10) or increasing pressure within the container (11) as far as a predefined test pressure, ascertaining a pressure profile (100) within the pressure chamber (10) over time, comparing the pressure profile (100) to a reference profile (200) in order to determine whether a leak is present within the container (11), wherein ambient conditions of the container (11) and/or the pressure chamber (10) are monitored and the reference profile (200) is adapted to changing ambient conditions.
