Abstract (en)
[origin: WO0002432A2] In order to test filter cartridges (50) with a threaded connection for leakage, said cartridge is placed on a plate (5) in a hermetic leakage test chamber (3, 5). A threaded head (15) is then screwed in the threaded connection of the filter cartridge (50) and the filter cartridge is then pulled towards the plate (5). A pressure difference is generated between the inside of the filter cartridge and the inner space of the test chamber (3, 5) and leakage is calculated on the basis of the behavior of pressure difference. The filter cartridge (50) is thus tested under actual operating conditions.
