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. TotalLeakage: 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.
