Paper and board. Determination of water vapour transmission rate of sheet materials. Dynamic sweep and static gas methods
This document describes general test methods for determining the water vapour transmission rate of sheet materials by means of a dynamic gas method or a static gas method. Depending on the method and specific apparatus employed, materials up to 38 mm thick and with water vapour transmission rates in the range from 0,05 g/(m2·d) to 65 g/(m2·d) can be tested. The basis of the function of the instrumental techniques is briefly described. Advice on calibration is given in Annex B.
