The ISO 28199-1:2021 "Evaluation of coating system performance in relation to paints and varnishes in relation to lame plating processes, Part 1: Vocabulary and preparation of test panels" standard specifies test panel prepative for coating materials and Measuring methods for their surface properties. The standard specifies terms and definitions related to coating performance, including film thickness, Color, surface texture, etc. In addition, it covers requirements for pretreatment of test panels, measurement of Coating thickness, Evaluation of Color and surface texture, etc. This standard aims to provide a consistent basis for evaluation of coating materials for research, development and production in industrial applications. Standardized testing methods ensure that the mass and performance of coating products meet the expected requirements.
