摘要： PROBLEM TO BE SOLVED: To provide a method of checking/testing for rapidly checking whether filler materials of various components have appropriate gas permeability based on standard indices by establishing the indices for standardly evaluating the gas permeability of filler materials.
SOLUTION: This testing device 1 includes: an outer frame 10 internally supporting a columnar test piece M formed of a filler material which is a testing object, coated with an airtight resin on its side face, and having a set height (L) and a constant cross-section area (A); a support 11 supporting an outlet end 12a of an air inflow pipe 12 causing air to flow thereinto on one side (m1) of an opened end face of the columnar test piece M while supporting the outer frame 10; a flow sensor 20 measuring the flow of air flowing through the air inflow pipe 12; a pressure sensor 21 measuring pressure of air flowing into the inflow pipe 12; and an air supply device 30 causing air to flow into the inflow pipe 12 at a set constant pressure. The testing device 1 is used to find an air permeability coefficient K=(L/h)×{Q/(A×t)} by using pressure (h) and flow (Q) measured at set time (measurement time t).
