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 pdf iso -16276-1

: 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. : The force at fracture is recorded (typically

: The force at fracture is recorded (typically in Megapascals, MPa), and the nature of the failure (adhesive vs. cohesive) is assessed visually. Areas tested will require repair once the test

: 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

: 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 .
