The mpweya permeability tester lakonzedwa ndi chopangidwa kwa simenti thumba pepala, thumba thumba pepala, chingwe pepala, kukopera pepala ndi mafakitale fyuluta pepala, etc., kuyeza kukula kwa mpweya permeability, chida ndi oyenera mpweya permeability pakati 1 × 10-2 ~ 1 × 102um/ (pa.s), osati pepala ndi lalikulu akhakula pamwamba.
Ndiko kuti, pansi pa zikhalidwe zotchulidwa, nthawi ya unit ndi kusiyana kwa mphamvu ya unit, gawo la pepala kupyolera mumayendedwe a mpweya. Mitundu yambiri ya mapepala, monga pepala la thumba la simenti, thumba la thumba, pepala lachingwe, pepala lojambula ndi pepala la mafakitale, liyenera kuyeza kupezeka kwake, chida ichi chapangidwa ndikupanga mapepala amitundu yonse. Chida ichi ndi oyenera mpweya permeability pakati 1 × 10-2 ~ 1 × 102um / (pa. S), si oyenera padziko lalikulu akhakula pepala.
Mapiritsi opumira amagwirizana ndi QB/T1667-98 "Mapepala ndi makatoni kupuma Tester", GB/T458-1989 "Mapepala ndi makatoni kupuma njira determinability" (Schobol). Iso1924/2-1985 QB/T1670-92 ndi miyezo ina yoyenera.
