AAMA 501.2-03: Evaluating Joints, Gaskets, and Sealant Details in the Glazing
AAMA 501.2-03 testing is designed for curtain walls. The testing occurs on the lowest typical floor for storefront or sloped glazing system checking. Before the testing can take place, the test area must be completely glazed according to the shop drawings and job specifications. If the glazing installation is not complete, then the testing results will not be accurate. The test area (typically 9.3 square meters) must include perimeter caulking, typical splices, frame intersections, and, if applicable, at least two entire vision lites and two entire spandrel lites containing an intermediate vertical member and an intermediate horizontal member. During testing, it’s imperative to remove any interior finish wall materials to gain visual access for examining water penetration.
