ISO 4628-4:2016 specifies a method for assessing the degree of cracking of coatings by comparison with pictorial standards.
ISO 4628-1 defines the system used for designating the quantity and size of defects and the intensity of changes in appearance of coatings and outlines the general principles of the system.
