The American Architectural Manufacturers Association (AAMA) has published a “Voluntary Specification for Anodized Architectural Aluminum.” AAMA 611-12 describes test procedures and requirements for high-performance (Class I) and commercial (Class II), architectural-quality aluminum oxide coatings applied to aluminum extrusions and panels for architectural products. The specification also covers anodized finishes produced in batch or continuous coil.
Updated from the 1998 version, AAMA 611-12 includes clarification of visual inspection language regarding surface imperfections, and addition of coating observation and angle inspection. The updated specification also contains additions and clarifications of finishes to the applicable Aluminum Association Designation System for aluminum pretreatments and finishes.
