Circle Test Method:
Leakage to Outside Total Leakage
Maximum duct leakage:
Post Construction, total duct leakage: (floor area x .08) = CFM@25 Pa
Post Construction, leakage to outdoors: (floor area x .06) = CFM@25 Pa
Rough -In, total duct leakage with air handler installed: (floor area x .06) = CFM@25 Pa
Rough -In, total duct leakage with air handler not installed: (floor area x .04) = CFM@25 Pa
Test Result: Ng- CFM@25Pa
