Instructions: Follow the procedure outlined above; put the appropriate information into the following test form.
Make certain to include information about the building location, and the type of fan/gauge used (on the front
page).
The test form is laid out in the same fashion as Retrotec’s FanTestic software program. Once this form is
completed, the information can be entered into FanTestic to provide the results of: Air flow at STP in CFM at 50
Pa, Air change rate per hour at 50 Pa, Flow/unit floor area in CFM/sqft at 50 Pa, Flow/unit enclosure area in
CFM/sqft at 50 Pa, Equivalent Leakage Area in sqin at 10 Pa, and LBL Effective Leakage Area in sq in at 4 Pa. These
results can be recorded on this test form in order to keep a paper record of this test.
