The Testing Categories of Fabric Waterproofing. The main indexes of the fabric waterproof are dip water grade, hydrostatic pressure resistance grade, and water permeation capacity, and there are two kinds of test methods: spray method and hydrostatic pressure method. In order to measure the water permeability or waterproofing of fabrics .After the water permeability test for fabric, the water vapour permeability of the fabric can be obtained according to the water vapor transmission rate unit conversion and the water vapor permeability formula. . It mainly tests the water vapor permeable of fabric in natural environment. In addition, we also have the instrument VIT165B, to .
water and covered with a fabric sample. The whole assembly is then weighed and reweighed after a certain elapse of time. The water vapour permeability of the fabric is the loss in weight of water in the cup, expressed in g/m2/day. Since the water vapour permeability is . Five testing instruments plus a new test apparatus were employed to evaluate the water vapor transport properties of fabrics with low, medium, and high vapor permeability. The test results show that the desiccant inverted cup method generated the highest water vapor transmission rate, followed by the new method, the dynamic moisture permeation .Energy Materials. Brock Conley, . Christopher Baldwin, in Comprehensive Energy Systems, 2018. 2.24.4.1.3 Moisture permeability. Moisture permeability is the material’s resistance to the water vapor diffusion through a unit of surface area. This can be experimentally determined using one of two methods, as described in ASTM standard E96M-15 [34].The two methods are the .
