is 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"

A high-strength adhesive (often epoxy) is used to bond the dolly to the coating.

The inspector notes the maximum force (in Megapascals, MPa, or Pounds per Square Inch, PSI) at which the failure occurred. Interpreting Failure Modes

The standard emphasises that test locations must be representative of conditions—e.g., near cut edges, where thickness is lowest, or areas with suspected over-coating of contaminants. pdf iso -16276-1

A tensile load is applied smoothly and continuously at a uniform rate until failure occurs. 📊 Evaluation and Expression of Results

The primary purpose of the document is to supplement the ISO 12944 series by unifying how paint strength is validated after application. Adhesion vs. Cohesion

is an international standard 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. In simpler terms, it is the definitive guide for inspectors and engineers on how to properly perform and evaluate a "pull-off" adhesion test on a painted steel structure. is titled: "Corrosion protection of steel structures by

If you are creating a post (e.g., for LinkedIn or a technical blog), here is a structured draft:

The individual breaking strengths and calculated mean value. Visual quantification of the failure modes (e.g., cohesive failure in primer, adhesive failure between primer and mid-coat). If you need help implementing this standard, let me know:

Cylindrical aluminum or stainless steel blocks (typically 20 mm in diameter) that are bonded to the coating surface. A tensile load is applied smoothly and continuously

The tensile load must be applied perpendicular to the plane of the coated substrate and increased at a uniform rate not exceeding 1 MPa/s until failure occurs. Understanding Assessment and Acceptance Criteria
