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.
Claims10
A method for measuring the permeability to gases of the wall of a hollow body made from polymer material, wherein it comprises a first step called the conditioning step in which a flushing gas flushes said hollow body, and a second step, called the measuring step, in which a measurement gas is introduced into said hollow body, wherein the flow rate of flushing gas is higher than the flow rate of measurement gas and wherein said flushing gas is sent into said hollow body without mixing with said measurement gas.
