: This standard was officially withdrawn by ASTM in 2008 . While it is no longer an active standard maintained by ASTM, it is still frequently referenced in industry specifications for its detailed preparation methods. Preparation Methods Included
While ASTM D2092 is specifically about preparing surfaces for , its methods are aimed at improving the adhesion of the applied coating. For a broader guide on preparing metal surfaces specifically for adhesive bonding (using glues or structural adhesives), other standards like ASTM D2651 (for aluminum) are more directly applicable. However, the fundamental surface activation and cleaning principles from D2092 are often relevant. Disclaimer: This post is for informational purposes only
The standard originally outlined eight distinct ways to treat new hot-dip or electroplated zinc coatings:
The heart of ASTM D2092 is its description of eight distinct surface‑treatment methods, each suited to different service conditions, zinc coating types, and application environments. These methods range from chemical conversion coatings to heat treatments and abrasive cleaning. The eight methods are summarized in the table below. : This standard was officially withdrawn by ASTM in 2008
Specialized field or shop preparations where visual confirmation of etching is desired. Method H: Clean Water Rinse and Weathering
