The work of preparing International Standards is normally carried out th

21、rough ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collab

22、orates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval

23、 criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that some of the elements of this document may be the su

28、tive 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 mill scale;b) the presence of surface contaminant

29、s, including salts, dust, oils and greases;c) the surface profile.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 that are available for clean

30、ing steel substrates, indicating the capabilities of each in attaining specified 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 r

31、equirements 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 recommendations are found in other documents, such as national standards and codes of practice. It will be necessary for users o

32、f these International Standards to ensure that the qualities specified are: compatible and appropriate both for the environmental conditions to which the steel will be exposed and for the protective coating system to be used; within the capability of the cleaning procedure specified.The Internationa

33、l 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 substrates; ISO 8504 Surfac

34、e preparation methods.Each of these International Standards is in turn divided into separate parts.It is important to note that numerical characterization of a surface profile is meaningful only when accompanied by an understanding of the errors of measurement and by the realization that different t

35、echniques may yield somewhat different numerical values for the profile. Estimates of measurement error associated with different techniques can be obtained from national or international standards or from the equipment manufacturers. As shown in Annex B, values given by the replica tape method alig

36、n well with those obtained using other parts of ISO 8503.Information regarding the magnitude of errors associated with use of replica tape is given in Annex A.Advantages of the replica tape method include the fact that it affords numerical characterization, yields a permanent record, works well on c

37、urved surfaces and benefits from a geographically broad base of user experience over a period of several decades.

38、s of blast-cleaned steel substrates Part 5: Replica tape method for the determination of the surface profile1 ScopeThis document describes a field method for measuring the surface profile produced by any of the abrasive blast-cleaning procedures given in ISO 8504-2. The method uses replica tape and

39、a suitable gauge for measuring, on site, the roughness of a surface before the application of paint or another protective coating.The method is applicable within the range of profile heights cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit meas

40、urement of average peak-to-valley profiles of 20 m to 115 m. The method is valid for surfaces that have been cleaned with abrasives.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

44、ape consists of a layer of crushable plastic microfoam coated onto a polyester substrate of highly uniform thickness (50 m 2 m). When compressed against a hard surface, the microfoam collapses and acquires an impression of the surface. The thickness of the replica is a measure of the surface profile

45、.When the replica film is coated with a thin (80 nm) layer of a ductile and optically reflective metal, such as indium, the replicated surface can be studied with an optical interferometric profiler. When the film INTERNATIONAL STANDARD ISO 8503-5:2017(E) ISO 2017 All rights reserved 1BS EN ISO 8503

46、-5:2017ISO 8503-5:2017(E)is coated with a similarly thin layer of a ductile and electron-emissive metal, such as gold, platinum or palladium, the replica may be studied with an electron microscope.NOTE This method measures an “average maximum peak-to-valley profile” because the anvils of the microme

48、-backed paper tape. The film shall be mounted over a hole (approximately 10 mm in diameter) in the centre of a section of the paper tape (approximately 53 mm 19 mm in size), which is printed with the grade of tape and the corresponding range of profile heights.NOTE Grades of replica tape are availab

Additional grades permit checking measurements at or near the low (20 m) and high (115 m) ends of this range. See Annex C.The tapes adhesive backing prevents movement of the replica film during the test and allows the sample identification and measured profile parameters to be recorded.The crushed microfoam can be further compressed and should therefore be handled with care, especially when m
