  • Patent number: 10776341
    Abstract: A method for quality assurance of filtration processes includes inserting a filter element (24) into a filtration device (14b) in which filter elements (24) can be subjected to integrity tests. The method further includes associating the integrity information with each filter element (24) in a filter element database (16; 34) connected to a shared data network (12) and saving the number of failed integrity tests performed on each filter element (24) as integrity information associated with that filter element. The saved tolerance setting has an auxiliary limit value, which when exceeded in a defined manner by the queried number of failed integrity tests performed on the identified filter element (24), causes a warning message to be sent to a predetermined monitoring unit (20) and the resulting blocking of the selected integrity testing device (14b) is maintained until a release message is received from the predetermined monitoring unit (20).

  • Patent number: 9810564
    Abstract: A method of determining an internal volume (V) of a filter or bag device includes pressurizing the device to a first pressure (p1) lower than a proof pressure by supplying a test gas, pressurizing the device to proof pressure (pp), and at the same time, measuring the mass flow (m) or the volumetric flow of test gas, determining the gas temperature (T), and determining the internal volume (V) based on the equation for ideal gases, such that: V=m×R×T/(pp?p1) where V is the internal volume, m is the mass flow, R is the gas constant, T is the gas temperature, pp is the proof pressure and p1 is the first pressure. A computer program product and a testing apparatus for performing the above-mentioned method also are provided.
