GB/T 8923.2-2008
ActivePreparation of steel substrates before application of paints and related products-Visual assessment of surface cleanliness - Part 2: Preparation grades of praviously coated steel substrates after localized removal of previous coatings
涂覆涂料前钢材表面处理 表面清洁度的目视评定 第2部分: 已涂覆过的钢材表面局部清除原有涂层后的处理等级
Application Summary AI generated
This standard defines the visual cleanliness grades for steel surfaces that have been partially stripped of existing coatings, specifying the acceptable levels of residual paint, rust, and other contaminants. It is applied in industrial maintenance and recoating operations, such as shipbuilding, bridge construction, and heavy machinery, where localized coating removal is performed before applying new protective layers. The standard ensures consistent quality assessment during surface preparation, guiding inspectors and applicators in determining whether a partially stripped surface is ready for repainting.
