⚠️ Surprisingly, the standard does not cover color anodizing (electrolytic or integral color). It assumes clear or naturally toned oxide. For colored anodizing, you must cross-reference JIS H 8601.

✅ Unlike the simpler dye spot test (ASTM), JIS’s admittance test gives a numeric value, allowing statistical process control in the anodizing plant. jis h 8625 pdf

⚠️ 9 µm (Class I) is roughly 0.35 mils. Compare to AAMA 611 which requires 10 µm (0.4 mils) or 18 µm for coastal. Some engineers argue JIS Class I is insufficient for aggressive beachfront buildings. ⚠️ Surprisingly, the standard does not cover color

If you are specifying anodized aluminum for building facades, curtain walls, or windows, this PDF document is arguably more critical than any other single reference. Unlike decorative anodizing standards, JIS H 8625 is exclusively for architectural exteriors . The standard acknowledges that buildings face acid rain, coastal salt, UV radiation, and alkaline cement runoff. ✅ Unlike the simpler dye spot test (ASTM),

Note: JIS H 8625 is the Japanese Industrial Standard for . Deep Review: JIS H 8625 – The Benchmark for Architectural Anodizing 1. Executive Summary JIS H 8625 is not just a specification; it is the de facto global benchmark for high-performance architectural anodizing. While other standards (ISO 7599, AAMA 611, BS 3987) exist, JIS H 8625 is uniquely rigorous because it separates anodized finishes into two distinct classes (Class I and Class II) based on sealing quality and corrosion resistance , rather than just coating thickness.
