25、ies). 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 committee. International organizations, governmental and
26、 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 with the rules given in the ISO/IEC Directives,
27、Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements o
28、f this part of ISO 8504 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 8504-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of steel substrates bef
29、ore application of paints and related products. This second edition cancels and replaces the first edition (ISO 8504-2:1992), which has been updated and editorially revised. ISO 8504 consists of the following parts, under the general title Preparation of steel substrates before application of paints

31、troduction 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 this performance are: a) the presence of rust and mill scale;
32、b) the presence of surface contaminants, including salts, dust, oils and greases; c) the surface profile. International Standards ISO 8501, ISO 8502 and ISO 8503 have been prepared to provide methods of assessing these factors, while ISO 8504 provides guidance on the preparation methods that are ava
33、ilable 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 system to be applied to the steel surface. Neither do they contain recommendations for the s
34、urface 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 national standards and codes of practice. It will be necessa
35、ry for the users of these International Standards to ensure 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
36、 four International Standards referred to below 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 substrate
37、s; ISO 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 obtain a surface that permits satisfactory adhesion of the priming paint to steel.
38、 It should also assist in reducing the amounts of contaminants that initiate corrosion. This part of ISO 8504 describes abrasive blast-cleaning methods. It should be read in conjunction with ISO 8504-1. Abrasive blast-cleaning is a most effective method for mechanical surface preparation. It is wide
39、ly applicable because this method of surface preparation has a number of versatile features listed below. a) The method allows a high production rate. b) The equipment can be stationary or mobile and is adaptable to the objects to be cleaned. ENISO85042:2001ISO -40582:(0002)E vi c) The method is app
40、licable to most types and forms of steel surface. d) Many different surface states can be produced, for example different preparation grades and surface profiles. e) Effects such as cleaning, peening, roughening, levelling and lapping can be produced. f) It is possible to remove selectively partly f
41、ailed coatings, leaving sound coatings intact.

42、described in this part of ISO 8504 are intended to be carried out by suitably trained and/or supervised personnel. The substances and procedures used in these methods may be injurious to health if adequate precautions are not taken. Attention is drawn in the text to certain specific hazards. This pa
43、rt of ISO 8504 refers only to the technical suitability of the methods and does not absolve the user from statutory obligations relating to health and safety. 1 Scope This part of ISO 8504 describes abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and
44、related products. It also contains information on the effectiveness of the individual methods and their fields of application. ISO 8504 is applicable to new and corroded steel surfaces and to steel surfaces that are uncoated or have been previously coated with paints and related products. For limita
45、tions, see note 2. NOTE 1 These methods are essentially intended for hot-rolled steel to remove mill scale, rust, etc., but could also be used for cold-rolled steel of sufficient thickness to withstand the deformation caused by the impact of abrasive. NOTE 2 There are several items that should be in
46、cluded in the purchasers procurement documents to supplement this part of ISO 8504. Items that should be considered as a part of surface preparation before coating are edge grinding, removal of grease and oil, porosity of welds, removal of weld spatter, removal of burrs and other sharp edges, grindi
47、ng of welds, filling of pits and other surface imperfections that may cause premature failure of the coating system (see ISO 8501-3 for more information) and the removal of water-soluble contaminants. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 8504.
