The ISO 10289-1999 standard specifies a method for evaluating the performance of decorative and protective metal and inorganic coatings on metal substrates under corrosion conditions. The standard assesses coatings through two evaluation aspects: their ability to protect substrates from corrosion and their ability to maintain Appearance integrity. Protection level (Rp) is used to describe the effect of coatings on preventing corrosion of substrates, while Appearance level (RA) assesses the degree of change in Appearance of coatings under corrosion or environmental influence. This standard applies to exposure testing under natural atmospheric, mobile or static conditions and is intended to provide an objective assessment of coating systems. The defects and edge protection of the specimen during testing are also specified in detail to ensure the accuracy and comprehensiveness of the evaluation. These rating systems are essential for coating manufacturers and users to ensure that the coating system provides reliable protection and aesthetic Appearance in actual use.
