ISO 4628-10-2016 standard specifies a test method for assessing filamentous corrosion of coatings after aging. The degree of filamentous corrosion on the coating surface is assessed by measuring the longest and common lengths of filaments. The standard updates the definition of filamentous corrosion, simplifies Accessories A, and revises the text and references to ensure the conformity and accuracy of the method. These changes make the evaluation process more standardized and more accurately reflect the actual performance of coatings.
