Gurley method

Gurley method

Gurley method

(OP)
Could someone explain me what is the Gurley method to determine the airflow through a material & give the relationship w/ the airflow in  ml/(min.mm².mbar) ?
thx

RE: Gurley method

Don't know if this helps...

Gurley numbers are used to indicate the relative permeability of membranes or materials...The number (in sec) is obtained by measuring how long a known volume of air at constant pressure takes to pass through a material.
Your constants would be air Pressure, Area of membrane...

Here is a website you might find interesting...
www.gpi-test.com. ; In the past, I've run across some good literature on this from WL Gore...the manufacturer of GoreTex!!
