Abstract:
A method for testing the sealing tightness of a specimen, containing a gas, in a film chamber made from flexible material. The film chamber is evacuated by a vacuum pump and the gas flow flowing out of the film chamber and generated by the vacuum pump is measured during the evacuation and is examined with respect to a possible leak of the specimen.
