Hygrothermal performance of building materials and products — Determination of water-vapour transmission properties — Box method 建筑材料和产品的湿热性能——水蒸气传输特性的测定——箱法

发布日期： 2007-07-04

                ISO 21129:2007规定了测定建筑材料水蒸气渗透性的盒子法。箱法主要用于测量具有低水蒸气阻力的材料的水蒸气渗透性，其中表面湿度传输阻力的影响不能忽略。

ISO 21129:2007 specifies a box method for determining the water-vapour permeability of building materials. The box method is used primarily to measure the water-vapour permeance of materials that have low water-vapour resistance, in which the influence of the surface-humidity transmission-resistance cannot be ignored.
