31、3-3:2012-06 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 that are known to influence this performance are:a) the presence of rust and

32、mill scale;b) the presence of surface contaminants, including salts, dust, 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)

33、provides guidance on the preparation methods which are available for cleaning 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 surfa

34、ce, nor for the surface quality provisions 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. Such provisions are found in other documents, such as national standards and codes of practice. It is n

35、ecessary 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 is exposed and for the protective coating system to be used; within the capability of the cleaning procedure specifi

36、ed.The four International Standards referred to above deal with the following 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

37、substrates; ISO 8504: Surface preparation methods.The optical microscope is one of the most widely used instruments for measuring surface profile. The method can be used by any laboratory equipped with a good microscope which has a calibrated focusing mechanism meeting the requirements of 5.1. This

38、procedure can also be used to determine the profile of a substrate after abrasive blast-cleaning either directly or from a replica.This method is based on that developed in the USA by the Steel Structures Painting Council (now the Society for Protective Coatings). lt entails averaging a series of ma

39、ximum peak-to-valley measurements obtained by focusing a specified microscope, first on the highest peak and then on the lowest valley in the same field of view, noting the distance of movement of the stage (or objective lens).This method has the disadvantage of requiring a series of tedious measure

40、ments, but good precision and agreement between laboratories and between operators can be obtained by specifying closely the field of view and depth of field of the microscope. To avoid a widespread divergence in measuring profile within and between laboratories, this method requires a significant n

41、umber of measurements as well as correct calibration, proper focus movement, standardized depth of field and field diameter of the microscope necessary to measure properly both coarse and fine profiles under a single set of conditions.ISO 8503-4 describes the procedure using a stylus instrument. ISO

42、 8503-1 specifies the requirements for ISO surface profile comparators and ISO 8503-2 describes their use. The many abrasive blast-cleaning procedures in common use are described in ISO 8504-2.EN ISO 8503-3:2012 (E) DIN EN ISO 8503-3:2012-06 41 ScopeThis part of ISO 8503 specifies the optical micros

43、cope and describes the procedure for calibrating ISO surface profile comparators conforming to the requirements of ISO 8503-1.This part of ISO 8503 is also applicable to the determination of the surface profile, within the range hy= 20 m to 200 m, of essentially planar blast-cleaned steel. The deter

44、mination can be carried out on a representative section of the blast-cleaned substrate or, if direct observation of the surface is not feasible, on a replica of the surface (see Annex E).NOTE Where appropriate, this procedure can be used for assessing the roughness profile of other abrasive blast-cl

47、abrasive blast-cleaned surfaces3 Terms and definitionsFor the purposes of this document, the definitions given in ISO 8503-1 apply.4 PrincipleThe test surface is observed over a specified field of view using a specified microscope. The microscope is adjusted, by movement of the objective lens (or th

48、e stage), to focus on the highest peak within the field of view. The distance, hy, moved by the objective lens (or the stage) in order to focus on the lowest valley within the same field of view is determined.The procedure is repeated to obtain values for a further 19 different fields of view, and calculation, of the arithmetic mean of the distance, hy, between the highest peak and lowest valley in each field of view, as the mean maximum peak-to-valley height, hy,
