: The force at fracture is recorded (typically in Megapascals, MPa), and the nature of the failure (adhesive vs. cohesive) is assessed visually.

: Users should note that pull-off testing is a destructive process . Areas tested will require repair once the test is completed, the extent of which depends on the project specification. 2. The Pull-Off Testing Procedure pdf iso -16276-1

: The coating and the face of the test cylinder ( dolly ) are cleaned and degreased. : The force at fracture is recorded (typically

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. Areas tested will require repair once the test

: The procedures are applicable to coatings of any thickness .

: For many applications, a circular cutting tool is used to cut through the coating down to the substrate around the dolly to isolate the test area.

: It traditionally applies to steel substrates with a thickness of at least 10 mm . However, the updated ISO 16276-1:2025 edition expands this scope to include substrates as thin as 3 mm .
