Spray Testing
AAMA 501 Kinetic Energy Spray Test
This test method also simulates a 44 mph wind-driven rain event in small, segmented areas using a standard 3/4 inch diameter hose in which a calibrated nozzle is attached with a calibrated pressure gauge. The spray is directed at a specific joint, crack, or defect to reveal potential water leakage and assist in identifying the point of entry and path of travel of suspect moisture intrusion.
AAMA 501.2 Spray Nozzle Test
Test simulates a wind-driven rain condition on a specific assembly and/or component. It can be useful in determining a specific cause and origin of moisture infiltration when it is used to test individual components of an exterior envelope area or assembly. Specific assemblies and/or interfaces of assemblies are isolated and subjected to controlled amounts of moisture instead of spraying water over a large area in an uncontrolled manner that will not reveal specific components or conditions that are the cause of water infiltration.
