ISO 8504-3-2018 standards specify methods of surface preparation for Coating and related products to prepare steel substrates prior to use, in particular manual and power tool cleaning methods. These methods are applicable to new and previously coated steel surfaces, ensuring the removal of rust, scale and Miscellaneous contaminants to obtain a surface cleanliness suitable for coating. Standard guidelines include specific operation steps for using hand tools such as chipping hammers, hand doctor blades, hand wire brushes, sandpaper, and power tools such as swirl/spin descalers, swirl/spin wire brushes, swirl/spin impact tools. In addition, the ISO 8504-3-2018 emphasizes methods for evaluating steel surfaces after cleaning to ensure that the required level of surface cleanliness is achieved.
