AAMA 611-26 is the FGIA voluntary specification for anodized finishes on architectural aluminum. It defines scope, terminology, finish designation practices, sample approval expectations, and test methods for color uniformity, gloss uniformity, coating thickness, corrosion resistance, weathering, seal testing, craze resistance, and sealant compatibility.
The document is intended to help architects, owners, fabricators, and finishers specify and verify anodized aluminum finishes for architectural products. It distinguishes between Class I and Class II anodic coatings and references related ASTM, AATCC, ISO, and FGIA standards used in testing and evaluation.
Application Scope: Architectural aluminum extrusions and panels with anodized finishes, including batch or continuous coil finishes used in building and façade applications.
