33、. DIN EN ISO 8503-1:2013-05 EN ISO 8503-1:2012 (E) 3IntroductionThe 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 perf

34、ormance are:a) the presence of rust and 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 th

35、ese factors, while ISO 8504 (all parts) 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

36、systems to be applied to the steel surface or 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 s

37、tandards and codes of practice. It is 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 is exposed and for the protective coating system to be used; within the capab

38、ility of the cleaning procedure specified.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

39、characteristics of blast-cleaned steel substrates; ISO 8504: Surface preparation methods.Irrespective of the procedures and the type of abrasive used for the preparation of steel substrates, the surface after blast-cleaning consists of random irregularities with peaks and valleys that are not easily

40、 characterized. Consequently, it was concluded that, because of this random nature, no method is capable of giving a precise value for the profile. Thus, it is intended that the profile be identified as either dimpled (where shot abrasives are used) or angular (where grit abrasives are used) and tha

41、t it be graded as “fine”, “medium” or “coarse”, each grade being defined by the limits specified in this part of ISO 8503. These surface characteristics are considered to give sufficient distinguishing features for most painting requirements.Particular attention, however, is drawn to the fact that t

42、he grades “fine”, “medium” and “coarse” represent different ranges in terms of roughness parameters, dependent upon whether these grades are applied to shot abrasive or grit abrasive blast-cleaned surfaces. In consequence, the effect produced on a given coating by a given grade “fine”, “medium” or “

43、coarse” is determined not only by the specific surface character but also by the specific roughness value Ry5or hybelonging to that grade. Where surface profile is particularly important, both the grade of the surface profile (“fine”, “medium” or “coarse”) and the type of abrasive which is to be use

44、d are to be specified.This part of ISO 8503 specifies the limits for the “fine”, “medium” and “coarse” surface for both dimpled and angular profiles, and specifies the design of ISO comparators for reference purposes.Requirements regarding the care of ISO surface profile comparators are given in Ann

45、ex A.ISO 8503-2 describes the method of using these ISO comparators. The many abrasive blast-cleaning procedures in common use are described in ISO 8504-2.DIN EN ISO 8503-1:2013-05EN ISO 8503-1:2012 (E) 41 ScopeThis part of ISO 8503 specifies the requirements for ISO surface profile comparators, whi

46、ch are intended for visual and tactile comparison of steel substrates which have been blast-cleaned with either shot abrasives or grit abrasives. This part of ISO 8503 also includes definitions of the terms used in the ISO 8503 series and requirements for the care of ISO surface profile comparators.

47、NOTE 1 ISO surface profile comparators are used for assessing, on site, the roughness of surfaces before the application of paints and related products or other protective treatments.NOTE 2 Where appropriate, these ISO comparators can be used for assessing the roughness profile of other abrasive bla
