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 effectiveness rating at each
corresponding ventilation rate
