Hardcoat Anodizing Specs: Reliable MIL-PRF-8625 Guide

Summary for hardcoat anodizing specs Discussion

Hardcoat anodizing specs are the focus of this thread, with the original question asking for the American standard for blackened anodizing and a later question asking for the equivalent in China. The discussion points to MIL-A-8625 / MIL-PRF-8625 Type III as the recognized hardcoat anodizing specification used worldwide. Chris Jurey, identified as Past-President of the International Hardcoat Anodizing Association, says Type III is recognized and used all over the world, and notes that an IHAA survey found ISO 10074 to be the only other specification widely used outside the United States. The thread does not provide a China-specific equivalent beyond that broader international context, so the practical takeaway is to use MIL-PRF-8625 Type III as the main reference and consider ISO 10074 where non-U.S. specs are needed.
