Résumé

The conventional way of measuring the permeability of a material is the standard cup test method, which is very time consuming. The paper describes an investigation into the feasibility of using a surface air dew-point probe (SADP), to significantly shorten the measurement time. An analysis is presented to show the degree of accuracy required for the measurement of the moisture content changes of the air flowing through the SADP in order to achieve accurate measurement of permeability. The requirement, however, may not be achievable with the dew-point temperature sensors currently available. An experimental method for solving this problem is suggested, based on experience gained in trial experiments.
