: Standardized glues (e.g., 2-pack epoxy) must be used to bond the dolly to the coating. 2. Testing Procedure
: A fascinating feature is how it categorizes where the break happens. It distinguishes between: Adhesion failure : The paint peels off the steel. Cohesion failure : The paint layer itself snaps in half.
Note: ISO 16276-1 is often cited alongside the older, well-known standard . While ISO 8501-1 focuses on preparation grades (like Sa 2.5), ISO 16276 provides a more detailed methodology for inspection and acceptance criteria.
: If the glue fails before the paint, the test is invalid and must be repeated. Acceptance Criteria

Results are expressed as the force per unit area (MPa or psi) and include a description of the failure type (e.g., adhesive failure between layers, cohesive failure within a layer). Where to Find the PDF
To clarify:
Ensuring the longevity of steel structures—bridges, offshore platforms, and industrial plants—depends heavily on the durability of their protective coating systems. A critical aspect of this protection is the adhesion of the paint to the steel substrate. , "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" , serves as the international standard for evaluating this crucial parameter on-site.
Temperature and humidity during the curing of the adhesive can significantly impact pull-off values. Conclusion It distinguishes between: Adhesion failure : The paint
While reading summaries online is helpful, nothing replaces the official for professionals. Here is why you need the full document saved on your tablet or laptop for field use:
ISO 16276-1 requires the inspector to report the type of failure, which is just as important as the numerical value:
