The theoretical approach for the determination of specific gas permeability coefficient in the time-variable pressure difference conditions of gas flow through porous material is presented. The obtained theoretical results are experimentally verified by the use of suitable modified and improved standard laboratory equipment. Method, involving variable gas pressure, is compared with standardized constant pressure method and a very good agreement was obtained.
