---|---|---|---|---|
Tested as per CAN/ULC-S741 with five 1-m2 membrane specimens and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 300 Pa |
unconditioned (prior to UV and heat aging) |
L/(s·m2) |
Air leakage rate at 75 Pa ΔP (based on linear regression of 30 data points) ≤ 0.02 L/(s·m2) |
0.0014 |
conditioned (after UV and heat aging) |
L/(s·m2) |
Where less than 0.01 L/(s·m2) for unconditioned specimens, the increase of the air leakage rate at 75 Pa ΔP for conditioned specimens ≤ 0.001 L/(s·m2). |
