water vapor transmission rate test
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.
