Choyesa choyezera choyezera mpweya chodziwikiratu chimagwiritsidwa ntchito kuwunika momwe mpweya wa zinthu za thovu la polyurethane umayendera. Mfundo yamakina ndiyo kuyesa momwe zimakhalira zosavuta kuti mpweya udutse ma cell mkati mwa thovu. Mtengo womaliza wokwanira wa mpweya ndiye mayeso osalunjika kwambiri kuti muwone momwe chisa cha uchi chimagwirira ntchito mu thovu. The F0031 air permeability tester idapangidwa motsatira miyezo yapadziko lonse lapansi ndipo imagwiritsidwa ntchito mwapadera kuyesa zida za thovu la polyurethane. Doko loyesa ndi 50 * 50 * 25mm. Pambuyo poyika chitsanzo, chipinda cha vacuum chimapangidwa, ndipo mpweya wopitirirabe umagwiritsidwa ntchito pokhapokha kuyesa kukayamba. Kuyesera kusanayambe, wogwiritsa ntchito akhoza kukhazikitsa mtengo wopanikizika pazithunzi zogwira. Kuyesera kukayamba, woyesa mpweya wa permeability amafika pamtengo wokhazikika pamlingo wina ndipo amangomaliza mayesowo.
