The ISO 5636-5:2013 standard specifies a method for determining the air permeability of paper and Cardboard using the Gurley method, which is suitable for paper and Cardboard with a Porosity between 0.1 µm/(Pa · s) and 100 µm/(Pa · s). The method calculates Porosity by measuring the time it takes for a volume of air to pass through a sample. The Gurley method is a classic vapor transmission rate test method, which is easy to operate and has good Repeatability. It is widely used in industries such as paper, printing and Encasement to evaluate the breathability performance of paper and help optimize production processes and product quality control.
