The ISO 4628-4:2016 standard specifies methods for assessing the degree of cracking of coatings. This standard applies to the evaluation of cracking defects in coatings during aging and weathering by comparison with graphic standards. The standard describes procedures for visual evaluation, including criteria for defining the number, size and depth of defects. This section, together with the Miscellaneous ISO 4628 series of standards, provides methods for assessing various degradation phenomena of coatings, thus helping to improve the quality control and maintenance of coatings.
