40、ation of water-soluble ferrous ionsEN ISO 8502-3:2017 (E) DIN EN ISO 8502-3:2017-05 4 IntroductionThe performance of protective coatings of paint and related products applied to steel is significantly affected by the state of the steel surface immediately prior to painting. The principal factors tha

41、t are known to influence this performance are as follows:a) presence of rust and mill scale;b) presence of surface contaminants, including salts, dust, oils and greases;c) surface profile.The ISO 8501, ISO 8502 and ISO 8503 series of International Standards have been prepared to provide methods of a

42、ssessing these factors, while the ISO 8504 series provides guidance on the preparation methods that are available for cleaning steel substrates, indicating the capabilities of each in attaining specified levels of cleanliness.These series of International Standards do not contain recommendations for

43、 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 direct influence on the choice of protective coating to be applied and on its performance. S

44、uch recommendations are found in other documents such as national standards and codes of practice. It will be necessary for the users of these International Standards to ensure that the qualities specified are compatible and appropriate both for the environmental conditions to which the steel will b

45、e exposed and for the protective coating system to be used, and within the capability of the cleaning procedure specified.The four series of International Standards referred to above deal with the following aspects of preparation of steel substrates before application of paints and related products:

46、 ISO 8501 on visual assessment of surface cleanliness; ISO 8502 on tests for the assessment of surface cleanliness; ISO 8503 on surface roughness characteristics of blast-cleaned steel substrates; ISO 8504 on surface preparation methods.Each of these International Standards is in turn divided into s

47、eparate parts.This part of ISO 8502 describes a procedure for the assessment, using a pressure-sensitive tape method, of the quantity and the particle size of dust on steel surfaces prepared for painting.In the painting schedule requirements of contractual documents giving details of surface prepara

48、tion by blast-cleaning, it is normally specified that all surfaces shall be free from surface contamination including oil, grease, dirt, dust and water-soluble salts.Dust on blast-cleaned steel surfaces can reduce the adhesion of subsequently applied organic coatings and, by absorbing moisture, might promote the corrosion of the blast-cleaned steel surfaces. Accumulation of dust more naturally occurs on horizontal surfaces, the interior of pipes, and in
