本文件描述了通过动态气体法或静态气体法测定片材的水蒸气透过率的一般测试方法。根据所采用的方法和具体设备，可以测试厚度达38mm且水蒸气透过率在0.05 g/(m2·d)至65g/(m2·d)范围内的材料。简要描述了仪器技术的功能基础。附录B给出了校准建议。
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.
