25、ermitted without license from IHS-,-,-EN IS0 8504-3:2001 Introduction The 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 thi
26、s performance 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 IS0 8501, IS0 8502 and IS0 8503 have been prepared to provide methods of assessing these factors, while IS0 850
27、4 provides guidance on the preparation methods that are available for cleaning 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 stee
28、l surface. Neither do they contain recommendations for the surface quality requirements 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
29、national standards and codes of practice. It will be 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 will be exposed and for the protective coating system to be
30、used; - within the capability of the cleaning procedure specified. The four International Standards referred to above deal with the following aspects of preparation of steel substrates: IS0 8501 - Visual assessment of surface cleanliness; IS0 8502 - Tests for the assessment of surface cleanliness; I
31、S0 8503 - Surface roughness characteristics of blast-cleaned steel substrates; IS0 8504 - Surface preparation methods. Each of these International Standards is in turn divided into separate parts. The primary objective of surface preparation is to ensure the removal of deleterious matter and to obta
32、in a surface that permits satisfactory adhesion of the priming paint to the steel. It should also assist in reducing the amounts of contaminants that initiate corrosion. This part ofISO 8504 describes methods for hand- and power-tool cleaning. It should be read in conjunction with IS0 8504-1. Hand-
33、and power-tool cleaning are methods of surface preparation that generally provide a surface cleanliness which is inferior to that achieved by abrasive blast-cleaning. When a result similar to that of abrasive blast-cleaning is required, these methods need in most cases the use of more than one type
34、of power tool which makes surface preparation complicated and expensive. It is usually not possible to remove oil, grease and corrosion-stimulating substances such as chlorides and sulfates. Power-tool cleaning will generally provide a better foundation for the priming paint than hand-tool cleaning,
35、 which will result in better paint performance. Hand- and power-tool cleaning are both suitable methods for surface preparation. Hand-tool cleaning particularly requires the use of priming paints having good surface wetting ability. Power-tool cleaning is appropriate when a higher-quality surface pr
36、eparation grade is required and when blast-cleaning is not permitted or the interested parties decide that it is not feasible. Representative photographic examples for St 2, St 3, PSt 2, PSt 3 and PMa are available (see IS0 8501-1 and IS0 8501-2) for assessing some new and previously coated steel su
37、rfaces cleaned using hand or power tools. Because of the many different situations that arise in the preparation of surfaces, these photographs may not be sufficient to describe specific instances and it is recommended that special photographs of a treated reference area that are acceptable to the i
38、nterested parties be produced for use as a basis for further surface preparation procedures.

39、:2001 1 Scope This part of IS0 8504 describes methods for hand-tool and power-tool cleaning of steel substrates before application of paints and related products. It applies both to new steelwork and to steel surfaces that have been coated previously and that show areas of breakdown requiring mainte
40、nance painting. It describes the equipment to be used and the procedure to be followed. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 8504. At the time of publication, the editions indicated were val

All standards are subject to revision, and parties to agreements based on this part of IS0 8504 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
