SpletISO 2528:2024 specifies a method for the determination of the water vapour transmission rate (often erroneously called "permeability") of sheet materials. This method is not generally recommended for use if the transmission rate is expected to be less than 1 g/m 2 per day or for materials thicker than 3 mm. In such cases the method specified in ... SpletThe value of breathability is calculated by measuring the quantity of moisture vapor through a fabric during a specified time period and reported as the moisture vapor transmission rate (MVTR) (Gokarneshan et al., 2015 ). Higher values indicate better removal of vapor and moisture, and prevention of the accumulation of gas and vapor.
