METHOD AND APPARATUS FOR TESTING A GAS CAPSULE

摘要

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.
