Notes:<br />
1. Core area is the open area of the louvre face (face area less<br />
louvre frames). Core Velocity is the airflow velocity through the<br />
core area of the louvre (1m x 1m).<br />
2. Free area of test size is calculated per AMCA standard 500-L.<br />
3. Wind Driven Rain Penetration Classes:<br />
Class Effectiveness<br />
A 1 to .99<br />
B 0.989 to 0.95<br />
C 0.949 to 0.80<br />
D Below 0.8<br />
4. Intake Discharge Loss Class 2<br />
Discharge Loss Coefficient is calculated by dividing a louvers’<br />
actual airflow rate vs. a theoretical airflow for the opening. It<br />
provides an indication of the louvers’ airflow characteristics.<br />
Discharge Loss Classes:<br />
Class Discharge Loss Coefficient<br />
1 0.4 and above<br />
2 0.3 to 0.399<br />
3 0.2 to 0.299<br />
4 0.199 and below<br />
(The higher the coefficient, the less resistance to airflow.)<br />
5. The AMCA Wind Driven Rain Test is performed in a laboratory<br />
environment and incorporates controlled wind, water and system<br />
airflow effects. In actual field installations, storms may create<br />
conditions not considered by the AMCA test. Penthouse and similar<br />
applications where wind can pass through multiple louvres in an<br />
enclosure is another condition that is not simulated by AMCA tests.<br />
These applications can create elevated water penetration rates<br />
through any louvre. Because of these uncontrolled situations, it is<br />
recommended that provisions to manage water penetration<br />
through louvres be included in the building design.<br />
