Leakage Testing Standards Highlights
Different standards are used throughout the world to specify duct air
tightness and leakage requirements. The PAN300 duct leakage test
system has a duct leakage application to automatically compare the
actual leakage flow with the maximum allowed leakage flow for EN
and SMACNA standards. Field technicians can also use the duct
leakage application to determine actual leakage flow and manually
compare it to maximum leakage from another standard. The PAN300
duct leakage test system cannot determine the appropriate leakage
classification for a given duct.
