      The GB/T 22819-2008 standard specifies a method for measuring the vapor transmission rate of highly breathable paper, suitable for papers with a Porosity greater than 1 × 10 ^ -5 μm/(Pa · s). The vapor transmission rate of the paper is evaluated by measuring the air Flow rate at a specified pressure difference. The standard provides an accurate evaluation of the performance of highly breathable paper, suitable for applications where the paper vapor transmission rate is required.
