Abstract:
The invention relates to a method for measuring the permeability to gases of the wall of a hollow body (6) made of polymeric material, characterized: in that it comprises a first conditioning step during which a flushing gas flushes said hollow body (6), and a second measuring step during which a measurement gas is introduced into said hollow body (6); in that the flow of flushing gas is greater than the flow of the measurement gas, and; the flushing gas is sent into the hollow body (6) without mixing with the measurement gas.
