: The total force needed to overcome the internal cohesive bonds of the paint or the adhesive bonds between layers/substrates.

: Adhesion measures the molecular bonding forces at interfaces; cohesion measures the internal strength binding an individual coating layer together. pdf iso -16276-1

ISO 16276-1 establishes the procedures for preparing the test area, applying the glue, performing the pull-off test, and calculating the results. It ensures that different inspectors in different parts of the world can perform the test in a repeatable and comparable manner. : The total force needed to overcome the

: 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 ensures that different inspectors in different parts

The surface of the cured coating and the face of the test dolly must be thoroughly cleaned and degreased. Lightly abrading the dolly face with sandpaper improves mechanical bonding with the adhesive. Step 2: Applying the Adhesive

The standard does not define a "pass" value for all projects. Instead, it provides a framework: The required breaking strength must be pre-specified in the project contract or technical specification. Results are typically evaluated based on a mean value

The mean value of the specified number of pull-off tests must be equal to or greater than the required value.
