ANSI/AMCA Standard 500-L-23 establishes uniform methods of testing air leakage, air performance (pressure drop), water penetration, resistance to wind-driven rain and wind-driven-sand, and operational torque.
ANSI/AMCA Standard 540-23 establishes uniform methods of laboratory testing the ability of a louver to remain unbreached by flying debris during a windstorm.
Superseding AMCA Publication 511-21, AMCA Publication 511-21 (Rev. 12-22) outlines technical procedures and the proper presentation of data for the certification of air-control devices through the AMCA Certified Ratings Program (CRP).
This 3-inch louver is listed with Air Movement and Control Association (AMCA) standards 540 for impact testing and 550 for high-velocity wind-driven rain.
