A method is provided for determining whether a pressure within a capsule is at or above a predetermined value. The capsule to be tested is of the type having a movable sealing element acting as a temporary seal to prevent leakage of gas from a mouth of the capsule. The capsule is connected to a plenum, the pressure of which is subsequently elevated. As the capsule is exposed to this elevated pressure, the pressure within the plenum is monitored. From this monitored pressure, it can be determined whether the sealing element is in sealing contact with the capsule under the elevated pressure. This, in turn, indicates whether the pressure within the capsule is at or above the predetermined value.

L'invention concerne un procédé permettant de déterminer si la pression d'une capsule est égale ou supérieure à une valeur prédéterminée. La capsule à tester comprend un élément d'étanchéité amovible servant de joint temporaire pour empêcher une fuite de gaz de l'embout de la capsule. La capsule est connectée à un plénum dont la pression est élevée en conséquence. Tandis que la capsule est exposée à cette pression élevée, la pression du plénum est surveillée. Il est possible de déterminer à partir de la pression surveillée si l'élément d'étanchéité se trouve en contact étanche avec la capsule sous la pression élevée. Ceci indique si la pression élevée de la capsule est égale ou supérieure à la valeur prédéterminée.
