Leakage Testing Standards Highlights
27
Should one of these conditions not be satisfied, then correcting
the leakage to standard conditions may be done using one of these
formulas:
1.
ACFM=SCFM * (460+T)/530
where T = actual dry bulb air temperature (ºF)
moisture is negligible
pressure between -20 and +20 inwg
2. ACFM = SCFM * 0.075/d
where d = air density from psychrometric chart
3. ACFM=lb dry air/minute * humid volume (ft
3
/lb dry air)
 The SMACNA standard does not specify the information to be
reported, but instead defers to project documents. However, the
SMACNA standard does include a sample test report that
includes:
o
Test date and place
o
Test personnel and witness
o
Building and project reference
o
Duct section tested
o
Specified leakage class, test pressure and duct construction
pressure class
o
Measurements of:

Ductwork surface area

Leakage flow and calculations required to determine
leakage flow
