摘要：A method and device for testing containers, the method calling for a differencein pressure to be generated between the pressure inside the container and the pressureimmediately surrounding the container, the behavior of one of these pressures

permitting the gas tightness of the container to be assessed. A pressure value is storedand subsequently compared with one of the pressures, the stored pressure value beingstored electronically and compared with at least one value of the output signal from apressure sensor. The container is housed in an enclosure which is connected to a pressureor suction line, and a pressure-value storage unit, a comparator unit and a pressuresensor are associated with the pressure or suction line.
