DIN EN ISO 8503-4:2012-06 IntroductionThe performance of protective coatings of paint

35、and related products applied to 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, dus

36、t, oils and greases;c) the surface profile.International Standards ISO 8501 (all parts), ISO 8502 (all parts) and ISO 8503 (all parts) have been prepared to provide methods of assessing these factors, while ISO 8504 (all parts) provides guidance on the preparation methods which are available for cle

37、aning steel substrates, indicating the capabilities of each in attaining specified levels of cleanliness.These International Standards do not contain provisions for the protective coating systems to be applied to the steel surface or for the surface quality provisions for specific situations, even t

38、hough surface quality can have a direct influence on the choice of protective coating to be applied and on its performance. Such provisions are found in other documents, such as national standards and codes of practice. It is necessary for the users of these International Standards to ensure that th

39、e qualities specified are: compatible and appropriate both for the environmental conditions to which the steel is exposed and for the protective coating system to be used; within the capability of the cleaning procedure specified.The four International Standards referred to above deal with the follo

40、wing aspects of preparation of steel substrates: ISO 8501: Visual assessment of surface cleanliness; ISO 8502: Tests for the assessment of surface cleanliness; ISO 8503: Surface roughness characteristics of blast-cleaned steel substrates; ISO 8504: Surface preparation methods.The stylus instrument i

41、s commonly used in the precision measurement of surface textures resulting from machining and abrading procedures. The method is highly reproducible and totally independent of the operator and, if required, some instruments can provide a graphical representation of the surface. This procedure can al

42、so be used to determine the profile of a substrate after abrasive blast-cleaning, either directly or from a replica.ISO 8503-3 describes the procedure using an optical microscope. ISO 8503-1 specifies the requirements for ISO surface profile comparators, and ISO 8503-2 describes the procedure for th

43、eir use. The many abrasive blast-cleaning procedures in common use are described in ISO 8504-2.EN ISO 8503-4:2012 (E) 4DIN EN ISO 8503-4:2012-06 1 ScopeThis part of ISO 8503 specifies the stylus instrument and describes the procedure for calibrating ISO surface profile comparators conforming to the

44、requirements of ISO 8503-1.This part of ISO 8503 is also applicable to the determination of the surface profile, within the range Ry5= 20 m to Ry5= 200 m, of essentially planar blast-cleaned steel. The determination can be carried out on a representative section of the blast-cleaned surface or, if d

45、irect observation of the surface is not feasible, on a replica of the surface (see Annex C).NOTE Where appropriate, this procedure can be used to assess the roughness profile of other abrasive blast-cleaned substrates.An alternative procedure is described in ISO 8503-3.2 Normative referencesThe foll
