采用杯法测定了10种常用建筑材料的水蒸气透过率。材料包括糖松、坚固的支撑纤维板、纤维板护套、刨花板、外部级胶合板、普通石膏板、牛皮纸、华夫板壁板、乙烯基覆盖石膏板和泡沫芯护套。对于每种材料，都进行了一系列杯形测量，并绘制了渗透率（或渗透率）作为整个试样平均相对湿度的函数。分别在24摄氏度（75华氏度）和7摄氏度（44华氏度）下进行的测量表明，温度对渗透率的影响不显著。渗透率测量值与文献中报道的其他测量值进行了比较，在大多数情况下，一致性良好。关键词:水蒸气渗透性，测量，建筑，材料，木材，胶合板，木刨花板，纤维建筑板，石膏板，板材，比较，相对湿度，温度，吸附: 研讨会论文，马里兰州巴尔的摩，1992年

A cup method was used to measure water-vapour transmission in 10 common building materials. The materials included sugar pine, sturdy-brace fibreboard, fibreboard sheathing, particleboard, exterior grade plywood, plain gypsum board, kraft paper, waferboard siding, vinyl-covered gypsum board, and foam core sheathing. For each material, a series of cup measurements was conducted, and the permeability (or permeance) was plotted as a function of the mean relative humidity across the specimen. Separate measurements, carried out at 24 deg C (75 deg F) and 7 deg C (44 deg F), indicated that temperature has an insignificant effect on permeability. The permeability measurements were compared with other measurements reported in the literature, and the agreement was good in most cases.KEYWORDS: water vapour permeability, measuring, buildings, materials, wood, plywoods, wood particle boards, fibre building boards, gypsum plasterboard, boards, comparing, relative humidity, temperature, adsorption
