ISO 4628-8-2012 《Paints and varnish coatings - Assessment of ageing - Number and size of defects and assessment of uniformly varying strength in Appearance - Part 8: Assessment of disbonding and corrosion around scratches》 Related products

This standard specifies methods for evaluating the disbonding and corrosion of coatings around scratch or Miscellaneous man-made defects in a corrosive environment. It applies to delamination and corrosion that may occur around scratch or man-made defects after coatings are exposed to a corrosive environment. Optical inspection image processing can assist the evaluation and is designed to provide information on the performance evaluation of coating systems in real environments. The standard details how these defects can be independently evaluated to obtain more accurate coating performance data.
