Air Duct Leakage HVAC 2011 Technical Paper

SMACNA published the HVAC Air Duct Leakage Test Manual in conjunction with the SMACNA HVAC Duct Construction Standards. Research proved that duct leakage could be well defined as a function of the static pressure and the surface area of the duct. This allowed for the introduction of leakage classes that could be used to calculate and accurately represent the leakage of air from ducts of various sizes and configurations.
