ASTM B580‑79 was first approved in 1973 and has been published in multiple versions: B580‑79 (original 1979 issue), B580‑79(2000) (reapproved 2000), B580‑79(2004), B580‑79(2009), B580‑79(2014), and B580‑79(2019). In 2019, the standard was reconfirmed but was still based on the 1979 technical content with no substantial changes. The ASTM webstore and other distributors list the 2019 version as “Active” or “Standard Cancelled” depending on the source—reflecting the transition to the 2025 edition. As of 2025, ASTM has issued , which is the current active version of the standard. The ASTM B580 standard categorizes anodic coatings into

Type A coatings, often referred to as "Hardcoat" or Type III anodizing in military specifications (MIL-A-8625), require a minimum thickness of 2.0 mils (50 µm). These coatings are dense, highly resistant to wear and abrasion, and are typically used for industrial machinery, gears, valves, and aerospace components. They are usually left unsealed to maintain maximum hardness unless corrosion resistance is the primary concern. Type B: Architectural Class I (Exterior) In 2019, the standard was reconfirmed but was
