stretch extent Explanation: From the link below: Densometers are the accepted standard for measuring the porosity, air-permeability or air-resistance of sheet-like materials such as papers, wovens, plastics and membranes. All Densometers measure the time required for a given volume of air (25cc to 400cc) to flow through a standard area of material being tested under light uniform pressure. So it's obvious from the definition that the unit is seconds per square millimeter (metric) or second per square inch (English) - s/mm2 or s/in2 Reference: http://www.gpi-test.com/4110.htm |
