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