AAC certification demonstrates that finished anodized aluminum products have been evaluated against defined technical requirements and acceptance criteria. It helps manufacturers build customer confidence and gives purchasers a consistent basis for evaluating supplier performance.

For manufacturers and anodizing facilities, certification offers a clear way to demonstrate conformity with applicable technical requirements. For OEMs, specifiers, and purchasers, it provides a consistent basis for evaluating anodized aluminum suppliers and establishing purchasing expectations.

Facilities that achieve AAC certification can demonstrate their commitment to anodized aluminum performance and benefit from:

• Greater customer and supplier confidence.
• Clearer purchasing expectations through common test methods and acceptance criteria.
• Market differentiation through independent verification.
• Ongoing accountability through annual audits and certification status controls.

The program covers conventional sulfuric and hard anodizing, including batch and continuous coil processes, for architectural, transportation, and industrial applications.

The AAC Certification Program evaluates applicable performance characteristics of anodized aluminum finishes and products, including:

• Oxide thickness
• Oxide density
• Corrosion resistance
• Seal quality
• Heat stability
• Color
• UV stability
• Abrasion resistance
• Hardness

The AAC Certification Program is designed to support confidence through independent oversight and transparent certification controls. Annual audits support continued certification, while audit recommendations do not automatically determine certification decisions.

• Independent: Audits, technical review, and certification decisions are controlled and separated to support impartial outcomes.
• Measurable: Certification is tied to defined test methods and acceptance criteria for anodized aluminum performance.
• Verifiable: Certified scope, covered sites, certificate number, and certification status can be confirmed through an authorized directory or controlled process.

The technical foundation, IAPMO 428-2026, establishes requirements for anodized aluminum products used in architectural, transportation, and industrial applications. It addresses batch and coil anodizing and provides test methods and acceptance criteria for functional and decorative finishes.
