22、steel is significantly affected by the state of the steel surface immediately prior to painting. The principal factors that are known to influence this performance are a) the presence of rust and mill scale; b) the presence of surface contaminants, including salts, dust, oils and greases; c) the sur
23、face profile. International Standards ISO 8501, ISO 8502 and ISO 8503 have been prepared to provide methods of assessing these factors, while ISO 8504 provides guidance on the preparation methods that are available for cleaning steel substrates, indicating the capabilities of each in attaining speci
24、fied levels of cleanliness. These International Standards do not contain recommendations for the protective coating systems to be applied to the steel surface. Neither do they contain recommendations for the surface quality requirements for specific situations even though surface quality can have a
