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. How to perform an Air Permeability test. The principle of air permeability testing involves measuring the airflow volume that passes vertically through a given area of the test sample under a specified pressure difference over a certain period and then calculating the air permeability rate. The pressure difference is a necessary condition for .
