Abstract

Für die Leckageprüfung von Filterpatronen (50) mit Gewindeanschluss wird diese (50) auf einem Teller (5) in eine dichte Leckageprüfkammer (3, 5) eingefahren. Dabei schraubt sich ein Gewindekopf (15) in den Gewindeanschluss der Filterpatrone (50) und zieht danach die Gewindepatrone gegen den Teller (5). Eine Druckdifferenz wird zwischen dem Innern der Filterpatrone und dem Innenraum der Prüfkammer (3, 5) erstellt und aus dem Druckdifferenzverhalten auf Leckage geschlossen. Dabei wird die Filterpatrone (50) unter Einsatzbedingungen in der Praxis geprüft.
