This part of ISO 8501<\/span><\/span> specifies a series of preparation grades for steel surfaces after removal\/partial removal of water-soluble contaminants, rust, previous paint coatings and other foreign matter by high-pressure water jetting. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerances for each grade as described in words. In addition, this part of ISO 8501<\/span><\/span> specifies both initial surface conditions and after-cleaning flash rust grades, also defined by written descriptions together with representative photographic examples.<\/p>\n

\n
\n NOTE 1\n <\/div>\n

Examples of foreign matter, other than paint residues, are salt, grime, dirt, mill scale, oil, grease and marine growth, e.g. algae.<\/p>\n<\/div>\n

This part of ISO 8501<\/span><\/span> relates the cleanliness of the surface to its visual appearance. In many instances, this is sufficient for the purpose but, for coatings likely to be exposed to severe environments, such as water immersion and continuous condensation conditions, consideration should be given to testing for soluble salts and other invisible contaminants on the visually clean surface by the physical and chemical methods which form the subjects of the various parts of ISO 8502<\/span><\/span>.<\/p>\n

The roughness characteristics of the surface should also be considered by reference to ISO 8503<\/span><\/span>, although it must be noted that preparation by high- pressure water jetting does not create a profile or significantly change an existing profile.<\/p>\n","protected":false},"excerpt":{"rendered":"
