EN ISO 4628-2:2016 Paints and varnishes - Evaluation of degradation of coatings - Designation of quantity and size of defects@ and of intensity of uniform changes in appearance - Part 2: Assessment of degree of blistering
This part of ISO 4628 specifies a method for evaluating the degree of bubbling of coatings by comparison with images. The images in this part of ISO 4628 show bubbles of sizes 2, 3, 4 and 5 and, for these sizes, bubbles of quantities (densities) 2, 3, 4 and 5. ISO 4628-1 specifies a system for evaluating the quantity and the The size of coating damage and the intensity of changes in the appearance of coatings and contains the principles of the evaluation system. This system is intended in particular for damage caused by aging and weathering and for uniform changes such as color changes, for example yellowing.
