Glossary
Rough-ln: 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 Teaks 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 pr€
Conditioned Volume: Volume of conditioned space (CFA X ceil
ACH50: Air changes per hour at 50 pascals of pressure
