A "dolly" (loading fixture) is glued to the coating surface. A pull-off apparatus then applies a perpendicular force until the coating detaches or a predefined strength is reached. Result Reporting:
serves as the definitive global benchmark for verifying that bond through "pull-off" testing. What is ISO 16276-1?
: The coating surface and the base of a test dolly are cleaned and roughened to ensure a strong bond. Gluing the Dolly
New inspectors often panic when they see bare steel (Surface E). However, if the required adhesion is 5 MPa and you pulled 6 MPa before the coating ripped off the steel cleanly, the (because the required force was achieved before failure). The PDF examples clarify this nuance.
