ISO 16276-1: The Standard for Pull-Off Testing in Corrosion Protection

: A portable tensile tester applies a uniform, increasing tensile force perpendicular to the surface.

: 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. pdf iso -16276-1

This standard provides a rigorous, standardized methodology for measuring the of protective coatings—a term that encompasses both adhesion (bond to the substrate) and cohesion (internal strength of the coating). 1. Scope and Application

: The procedures are applicable to coatings of any thickness . ISO 16276-1: The Standard for Pull-Off Testing in

: The coating and the face of the test cylinder ( dolly ) are cleaned and degreased.

: A suitable adhesive (typically a 2-pack epoxy or cyanoacrylate) is used to bond the dolly to the coating surface. : A suitable adhesive (typically a 2-pack epoxy

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