GAS PERMEABILITY TEST PIECE, PRODUCING METHOD OF GAS PERMEABILITY TEST PIECE, GAS PERMEABILITY TEST PIECE PRODUCING DEVICE, AND GAS PERMEABILITY EVALUATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a gas permeability test piece capable of reducing an influence of gas entering from a film end surface, and further accurately evaluating gas permeability; a producing method of the gas permeability test piece; a gas permeability test piece producing device; and a gas barrier permeability evaluating device.;SOLUTION: A gas permeability test piece 100 includes: a film 21; a corrosive metal layer 22 formed on at least a part of one surface 21b of the film 21; and a low gass permeable non-corrosive material 23 for sealing the corrosive metal layer 22 and the one surface 21b of the film 21 on which the corrosive metal layer 22 is formed. An end surface 21a of the film 21 is sealed by the low gas permeable non-corrosive material 23.;COPYRIGHT: (C)2013,JPO&INPIT
