METHOD AND DEVICE FOR CARRYING OUT AN INTEGRITY TEST ON A FILTER ELEMENT

摘要

A method for carrying out an integrity test on a filter element has the steps: filling at least one vessel (1), in which a filter element (F) to be tested is arranged, with a fluid, – setting the pressure of the fluid in the vessel (1) to a predetermined specific test pressure, maintaining the specific test pressure in the vessel (1) with controlled replenishment of fluid into the vessel (1) and/or with a controlled change in internal volume of the vessel (1), – determining an integrity characteristic variable for the filter element (F) in a manner dependent on the controlled replenishment of fluid into the vessel (1) and/or in a manner dependent on the controlled change in internal volume of the vessel (1) before a substantially continuous volume flow of fluid, which is required for maintaining the specific test pressure in the vessel (1), arises. A corresponding device for carrying out an integrity test on a filter element is also proposed.
