ISO 4628-1 defines the system for designating the quantity and size of defects and the intensity of uniform changes of coatings and outlines the general principles of the system. This system is intended to be used, in particular, for defects caused by ageing and weathering, and for uniform changes such as colour changes, for example yellowing. ISO 4628-6 includes photographic images of adhesive tapes with different amounts of pigment particles adhering to them. The images can be used to determine the degree of defects.
