## Abstract

The reference adhesion test for organic coatings (including powder coatings) on metallic substrates. Test method A is an X-cut for thick coatings; Method B is a cross-hatch (typically 6x6 or 11x11 grid) for thinner coatings. Adhesion is rated on a 0-5 scale (5B = no flaking; 0B = greater than 65% removal). The production-floor QC method of record for powder coat adhesion on aluminium and steel substrates.
