Material e.g. polymer, permeability or fabric clearance testing device, has measuring cell, where sample is divided after placement in cell such that permeability or clearance of medium of substance takes place exclusively through sample

摘要

The device has a measuring cell (1), sample space (2), measuring space (3) and a sample (4). The sample is placed in the measuring cell, where the sample is divided after placement in the measuring cell in such a manner that permeability or fabric clearance of a medium of a permeable substance takes place exclusively through the sample. The sample is a solid state body, which is a polymer, plastic foil, package, cover, paper and wood.
