Push-off testing methodologies and laboratory-only test coupon rules 3. The Pull-Off Testing Methodology

What (epoxy, polyurethane, zinc-rich primer) are you evaluating? Is this for shop inspection or field testing ?

The terminology used in ISO 16276-1 to cover both failure types. 2. Key Aspects of the ISO 16276-1 Standard Equipment Requirements

Requires a with specified calibration.

To ensure representative testing, ISO 16276-1 mandates specific inspection areas and sampling plans. This ensures that the entire structure is properly assessed rather than relying on a single, isolated test. Acceptance/Rejection Criteria

Only by comparing the MPa value and the fracture pattern against the acceptance tables in the ISO 16276-1 PDF can you make a pass/fail decision.

: Standardized glues (e.g., 2-pack epoxy) must be used to bond the dolly to the coating. 2. Testing Procedure pdf iso -16276-1

It applies to coating systems applied to steel structures, generally with a thickness not less than 10 mm.

One of the most quoted parts of is the acceptance criteria. However, engineers often misinterpret the “5 MPa threshold.”

: A specialized adhesive (often cyanoacrylate or epoxy) is used to glue the dolly to the coating. It must cure completely before testing. The terminology used in ISO 16276-1 to cover

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.

: Procedures for measuring the adhesion of a coating system to a steel substrate using portable pull-off adhesion testers. Acceptance Criteria

In the event of premature coating failure, testing according to ISO 16276-1 provides legally and technically defensible data to identify whether the failure was due to poor adhesion or internal material weakness. and acceptance criteria for
