One of the most valuable aspects of is its framework for deciding whether a paint system passes or fails.
is the definitive international standard for measuring the corrosion protection of steel structures through the pull-off testing of protective paint systems . Specifically, the standard establishes uniform on-site procedures to assess the fracture strength (adhesion and cohesion) of coatings. Originally published in 2007, the standard was comprehensively updated to ISO 16276-1:2025 , which expands its field applications by lowering the minimum steel substrate thickness threshold from 10 mm down to 3 mm. pdf iso -16276-1
ISO 16276-1:2007, 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 One of the most valuable aspects of is
is the definitive guide for assessing the mechanical strength of paint coatings on steel. By standardizing the pull-off testing procedure, it ensures that the protective barrier shielding our infrastructure from corrosion is robust, reliable, and built to last. : Minimum of 10 mm (thinner substrates require
: Minimum of 10 mm (thinner substrates require reinforcement using the "sandwich technique" per ISO 4624).

Clean the surface of the coating to remove grease, moisture, and dust. Lightly abrade the face of the test dolly to improve adhesive bonding. 2. Dolly Attachment
