If a single test value falls significantly lower than the rest, the inspector must evaluate the failure mode. If it is a glue failure, it is discarded. If it is an adhesive failure of the coating, further testing in that specific zone is required to map out the extent of the underperforming application. Why Having the Official PDF is Crucial
Exclusively steel structures with a minimum thickness of 3 mm
A specialized pull-off adhesion tester is attached to the dolly. The instrument applies an increasing, perpendicular tensile force to the dolly until the coating is pulled away from the substrate. pdf iso -16276-1
Only by comparing the MPa value and the fracture pattern against the acceptance tables in the ISO 16276-1 PDF can you make a pass/fail decision.
To tailor further details, what are you focusing on, or do you need assistance drafting an inspection checklist based on this standard? Share public link If a single test value falls significantly lower
Engineers, asset owners, and NACE/AMPP-certified inspectors require the official ISO 16276-1 PDF document to guarantee technical compliance. Relying on summaries can lead to costly mistakes. The official PDF provides:
To ensure representative testing, ISO 16276-1 mandates specific inspection areas and sampling plans. This ensures that the entire structure is properly assessed rather than relying on a single, isolated test. Acceptance/Rejection Criteria Why Having the Official PDF is Crucial Exclusively
If you want, I can:
It uses a pull-off principle where a dolly is glued to the coating and then pulled perpendicularly until it fails.
