AAMA 502-12: Verifying Air Infiltration and Water Penetration Resistance of Installed Fenestration Products
AAMA 502-12 verification testing is applicable during construction and prior to the issuance of the building occupancy. However, it is to be completed no more than six months after the fenestration product is installed. During AAMA 502-12 verification testing, an air test chamber is attached and sealed to the wall or roof construction in order to create a pressure differential across the entire area and to seal the perimeter. The testing needs to be performed and completed as soon as possible after the fenestration product is installed and before drywall or other interior finish wall/roof materials are installed. In order to successfully complete the testing, interior materials will have to removed from the testing area for visual access, if they have already been installed.
