To receive the AMCA seal, louvers must meet certain test criteria. The tests are based on a 48" x 48" size.
The louvers are tested without birdscreens and must be mill finished. The water test is conducted at a rainfall
of 4" per hour during a 15- minute period. The AMCA Certified Ratings Seal applies to air capacities in the
intake mode only. See page 12 for complete free area information.
