Water vapor permeability is a measure of the passage of water vapor through a material. It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR) - which is basically the mass of water vapor that is transmitted through a measured area in a specific unit of time under specified conditions of temperature and humidity.The water vapour permeability index is calculated by expressing the water permeability of textiles as a percentage of the water vapour permeability of a reference fabric which is tested in a water vapor permeability test. After the water permeability test for fabric, the water vapour permeability of the fabric can be obtained according to the . This paper focuses on the various methods to test moisture permeability and the analysis of the influencing factors of test results. Currently, outdoor sports are relatively active, and the outdoor clothing needed will be paid more attention. A good outdoor sportswear should have its own unique characteristics. Water vapor permeability is an important basic one..
ASTM E96-22: Standard Test Methods for Gravimetric Determination of Water Vapor Transmission Rate of Materials addresses two testing procedures for determining the water vapor transmission rate (WVTR) of numerous materials, both of which can be incredibly useful for knowing the potential risks posed on the materials in different humidity levels.the time rate of water vapor transmission through unit area of flat material or construction induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions • Water Vapor Permeability: the time rate of water vapor transmission through unit area of flat material of Real time curves display of transmission rate, water vapour concentration, temperature and humidity; curves can be easily zoomed and moved.

surface. This was independent of the WRB’s permeability • Water entry from leaks, such as seen at the wall-roof interface, overwhelms any water intrusion due to solardriven vapor from water absorbed into cladding materials. Therefore, maximizing drying both to the inside and outside is recommended. 1Carmeliet, J., A. Karagiozis, and D .
