Glossary
Rough -In: After installation of the complete air distribution system but before installation of insulation and
sheet rock. Allows for access to all duct seams and connections for re-evaluation of seal integrity if standard
is not met in intitial test.
Post Construction: At or near final inspection. The home must be complete enough to pressurize the home
to 25 pa.
Total Leakage: Aggregation of the entire systems duct leakage in a duct test.
Leakage to Exterior: Aggregation of all duct system leaks to the exterior of the CFA in a duct test.
Pascal (pa): Unit of pressure
CFA: Conditioned floor area in square feet
CFM25: Cubic feet per minute of air leakage at 25 pascals of pressure
CFM50: Cubic feet per minute of air leakage at 50 pascals of pressure
Conditioned Volume: Volume of conditioned space (CFA X ceiling hieght)
ACH50: Air changes per hour at 50 pascals of pressure

❑ Duct tightness testing is not required. The total leakage test is not required for ducts and air handlers located
entirely within the building thermal envelope. Ducts located in crawl spaces do not qualify for this exception.
Air Handler in conditioned space? 0 yes I no Air Handler present during test? 1j yes 0 no
Circle Test Method: Leakage to Outside
Maximum duct leakage: 2
Post Construction, total duct leakage: (floor area x .04) = (P7 CFM@25 Pa
Post Construction, leakage to outdoors: (floor area x .04) = CFM@25 Pa
Rough4n, total duct leakage with air handler installed: (floor area x .04) = CFM@25 Pa
Rough4n, total duct leakage with air handler not installed: (floor area x .03) = CFM@25 Pa
Test Result: L-1 1 CFM@25Pa
