Five 1 m2 membrane specimens tested and measured for air permeance at a minimum of six air pressure differentials (DP) between 0 and 250 Pa (unconditioned specimens) |
Air leakage rate at 75 Pa ΔP (based on linear regression of 30 data points) ≤ 0.02 L/(s·m2) |
0.004 L/(s·m2) |
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. |
