STANDARD FILM FOR CORRECTION OF WATER VAPOR PERMEABILITY MEASUREMENT DEVICE, METHOD FOR MANUFACTURING SAME, STANDARD FILM SET FOR CORRECTION, AND CORRECTION METHOD USING SAME

摘要

An object of the present invention is to provide a standard sample for calibration that can be applied to many water vapor permeability measurement apparatuses without requiring a dedicated connection section and can be calibrated by a forming mechanism similar to that of a conventional film sample and measurement conditions. It is also an object of the present invention to provide a calibration standard film capable of offsetting changes in water vapor permeability due to physical properties of an adhesive used for bonding, for example, by correcting WVTR values using a plurality of calibration standard samples And a method of calibration and calibration. The standard film for calibration 10 according to the present invention has a barrier layer 12 on a resin film 11 and the barrier layer 12 has at least one pore 13 of 10 ^-3 g (Mm) of the pores 13 and L [m] of the thickness of the resin film 11 in the standard film for calibration of the water vapor permeability measuring apparatus for measuring the water vapor transmission rate , R / L? 5.
