A method for carrying out an integrity test on a filter element includes filling a fluid into at least one vessel (), in which a filter element (F) to be tested is arranged. The method proceeds by setting the pressure of the fluid in the vessel () to a predetermined test pressure, and maintaining the test pressure in the vessel () with controlled replenishment of fluid into the vessel () and/or a controlled change in internal volume of the vessel (). The method continues by determining an integrity characteristic variable for the filter element (F) in a manner dependent on the controlled replenishment of fluid into the vessel () and/or dependent on the controlled change in internal volume of the vessel () before attaining a substantially continuous volume flow of fluid for maintaining the specific test pressure in the vessel ().
