The principles of EN 13030 are replicated in the USA under the AMCA Standard 500-L, "Laboratory Methods of Testing Louvers for Rating"All of our louver systems have been tested either by BSRIA or by AMCATwo key performance areas:1. Rain Defence ClassificationThe ability to prevent rainwater from penetrating the louverClass EffectivenessMax. allowed rain penetration l/h/m²11 to 0.990.7520.989 to 0.953.7530.949 to 0.8015.004Below 0.80Greater than 15.00NOTE: Water Penetration Effectiveness is measured for each of eight face velocities between 0m/s and 3.5m/s under fan-driven wind at a speed of 13m/s and water sprayed as rainfall at a rate of 75 l/h conditions.2. Discharge Loss Coefficient ClassificationA high coefficient means low resistance and high airflow performanceClassAirflow EffectivenessPerformance Rating10.4 to 1Excellent20.3 to 0.399Very Good30.2 to 0.299Good40.199 & belowFairIf you are interested in our product or have any questions.
