ABSTRACT:
A method is made available for conducting an integrity test of filter elements (3), in particular of sterile filters. The integrity test involves direct measurement, at constant pressure, of a liquid flow on the inflow side of the filter element (3) to be tested. The test method is practically independent of changing environmental conditions, provides a result which is not distorted by a change of pressure on the inflow side of the filter element, and permits a very short measurement time.
