PERFORMANCE REQUIREMENTS FOR ANODIZED ALUMINUM FINISHES AND PRODUCTS
IAPMO 428-2026 Conformity Assessment Document
The IAPMO 428-2026 Conformity Assessment Document establishes a framework for evaluating anodized aluminum finishes and products against defined performance requirements. Developed in collaboration with industry experts and the Aluminum Anodizers Council (AAC), the document provides minimum quality requirements, test methods, and acceptance criteria for anodized aluminum used in architectural, transportation, and industrial applications.
The conformity assessment program is intended to promote consistency, reliability, and confidence in anodized aluminum products by providing an independent method for verifying compliance with established performance requirements.
