The AAMA 501.2 test is a Quality Assurance and Diagnostic Water Field Check of Installed Storefronts, Curtain Walls and Sloped Glazing Systems
Scope of Testing:
This particular test is utilized as a field quality control assurance measure to check the water tightness of commercial glazing systems.
Products to Test:
This test may be used for all storefronts, curtain walls, window walls, sloped glazing, skylights, fixed atriums, and other components that may have gaskets and glazing that are intended to be watertight.
Using the hand-held AAMA 501.2 Spray Wand assembly (with type B25 #6.030 nozzle, calibrated water pressure gauge, water inlet control valve, and 3/4-inch water hose feed line) the laboratory trained technician applies water perpendicular to the test specimen (while maintaining a distance of 12-inches) and adjusting the spray to stay between 30-35 PSI.
The nozzle of the wand is moved back and forth across horizontal and vertical sections of the test area at a rate of 1-minute per lineal foot (and not to test in sections greater than 5-feet at any given time). The test manager remains on the inside during the test to observe for any potential water intrusion
The system tested either meets (passes) or does not meet (fails) the performance criteria for water penetration resistance as allowed in the test method.
