摘要：A process enabling the measurement of the internal volume of a closed vessel (2), either gastight or non-gastight, by means of a permeation test in a "quasi-static" modality, with or without a prior tightness test. The tests are carried out by connecting the vessel (2) to a measurement device (1) consisting of a membrane (4) and a pressure gauge (5) - the measurement device being connected to a measurement gas supply, or to a gas extraction system, via a valve (6). The measurement apparatus also includes a second pressure gauge (7) and a thermometer (8) as well as a timer. By using a membrane (4) of known permeance, after having calculated a possible corrective term for any leakages, the relation linking the various parameters is resolved with respect to volume.
