| Five 1-m2-membrane specimens tested and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 250 Pa |
conditioned specimens |
Where less than 0.01 L/(s·m2) for unconditioned specimens, the air leakage rate for conditioned specimens must not increase by more than 0.001 L/(s·m2) at 75 Pa pressure difference. |
