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:
In some cases, the coating is cut around the dolly to isolate the test area from the surrounding paint. pdf iso -16276-1

The standard, officially titled "Corrosion protection of steel structures by protective paint systems — Assessment of, and acceptance criteria for, the adhesion/cohesion (fracture strength) of a coating — Part 1: Pull-off testing" , is a critical benchmark for quality control in industrial coating applications. and acceptance criteria for
