ASTM B580 is the Standard Specification for Anodic Oxide Coatings on Aluminum. It defines the requirements for the finish on aluminum and aluminum alloy products.
In the ASTM naming convention, the number after the hyphen indicates the year of adoption or last revision (in this case, 1979).
Many defense and aerospace components produced from 1980 through the mid-1990s were manufactured to this specific revision. If you are maintaining aging aircraft, military ground vehicles, or naval equipment, the original drawings may explicitly call out "ASTM B580-79." To validate a repair or replacement part, engineers must reference the exact standard used at the time of original manufacturing. astm b580-79 pdf

| Old Standard | Modern Replacement(s) | Notes | |---|---|---| | ASTM B580-79 (Type I) | ASTM D3933 (for adhesive bonding prep) | For paint adhesion, surface preparation specs are more relevant. | | ASTM B580-79 (Type II Hard Coat) | MIL-A-8625 (Type III) or AMS 2469 | Military and aerospace standards have largely superseded ASTM B580. | | General Anodizing | ISO 7599 (for decorative) or ISO 10074 (for hard anodizing) | International standards are now more common in global supply chains. |
Patent disputes, failure analysis, and product liability cases often require reviewing the state of the art at a specific point in time. ASTM B580-79 represents the industry baseline for anodizing in the late 1970s. Legal teams and forensic engineers search for the PDF to establish what constituted "acceptable practice" when a component was originally made.
