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
ISO 16276-1: The Standard for Pull-Off Testing in Corrosion Protection
ISO 16276-1 is primarily designed for of protective paint coatings on steel structures. pdf iso -16276-1
: A portable tensile tester applies a uniform, increasing tensile force perpendicular to the surface.
: The force at fracture is recorded (typically in Megapascals, MPa), and the nature of the failure (adhesive vs. cohesive) is assessed visually. : A portable tensile tester applies a uniform,
: The procedures are applicable to coatings of any thickness .
: 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 : The procedures are applicable to coatings of any thickness
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.
: 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.
