A break at the interface between two distinct layers. For example, a failure between the steel substrate and the primer (A/B), or between the primer and the topcoat (B/C). This often points to poor surface preparation or incompatibility between paint layers.
The standard specifies detailed preparation procedures:
The current version of the standard is . It supersedes the previous version, ISO 16276-1:2007, and introduces several key updates. The most significant changes are: pdf iso -16276-1
A high-strength glue (usually a solvent-free epoxy or cyanoacrylate) that secures the dolly to the paint without damaging the coating matrix.

Inspectors examine the "fracture face" to determine if the failure was: Failure between the paint and the steel. Failure within a single layer of paint. Inter-coat: Failure between two different layers of paint. Key Considerations for Inspectors Plain English Reporting: ISO House Style | | Standard Designation | Format | Price
