21、tion of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through 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 committ
22、ee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance
23、with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires appr
24、oval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

29、ings 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 contaminants, includ
30、ing 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) provides guidance on the preparation methods which are ava
31、ilable 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 surface or for the surface quality provisions for specific situ
32、ations, 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 necessary for the users of these International Standards to
33、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 specified.The four International Standards referred to above deal
34、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: Surface preparation methods.The stylu
35、s instrument is 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 pr
36、ocedure can also 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 pr
37、ocedure for their use. The many abrasive blast-cleaning procedures in common use are described in ISO 8504-2.

39、omparators 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 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 b
40、last-cleaned surface or, if direct 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
