- Beginning point of water penetration (@0.01oz. / ft2 of free area) — 1, 250 fpm (6. 35 m/s)
- Free Area: 52.5 % , based on a test sample of 48 in (1219 mm) x 48 in (1219 mm)
- Pressure drop @ 1,000 fpm free area velocity — 0. 39 in. wg ( 97 Pa)
- Discharge loss coefficient Classification — Class 3
WIND DRIVEN PERFORMANCE
The louver test was based on a 39.375 in. (1.0 m) x 39.375 in. (1.0 m) core area unit tested at a
rainfall rate of 3 in. per hour (75 mm/hr) and with a wind directed to the face of the louver at a
velocity 29mph (13 m/s) as well as a rainfall rate of 8” per hour (203 mm) and a wind of 50 mph
(23.3 m/s). The test data shall show the water penetration ef
fectiveness rating at each
corresponding ventilation rate.
