The work of preparing International Standards is normally carried ou
9、t 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 non-governmental, in liaison with ISO, also take part in the work. ISO co
10、llaborates 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, Part 3. Draft International Standards adopted by the technical committees
11、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 of this part of ISO 8504 may be the subject of patent rights. ISO shall not
12、 be held responsible for identifying any or all such patent rights. International Standard ISO 8504-1 was prepared by Technical Committee ISO/TC 35,Paints and varnishes, Subcommittee SC 12,Preparation of steel substrates before application of paints and related products. This second edition cancels
13、and replaces the first edition (ISO 8504-1:1992), which has been updated and editorially revised. ISO 8504 consists of the following parts, under the general titlePreparation of steel substrates before application of paints and related products Surface preparation methods: ?Part 1: General principle
14、s ?Part 2: Abrasive blast-cleaning ?Part 3: Hand- and power-tool cleaning Further parts are planned. -,-,- ISO 8504-1:2000(E) ISO 2000 All rights reservedv Introduction The performance of protective coatings of paint and related products applied to steel is significantly affected by the state of the
15、 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, including salts, dust, oils and greases; c)the surface profile. International Standards ISO 8501, ISO 8
16、502 and ISO 8503 have been prepared to provide methods of assessing these factors, while ISO 8504 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 Stand
17、ards do not contain recommendations for the protective coating system to be applied to the steel 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 t
18、o 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 the users of these International Standards to ensure the qualities specified are ?compatible and appropriate both for the environmental co
19、nditions 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 four International Standards referred to below deal with the following aspects of preparation of steel substrates: ISO 8501 Visual assessment
20、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. Each of these International Standards is in turn divided into separate parts. This part of ISO 8504 de
21、scribes the general principles for the selection of surface preparation methods. It should be read in conjunction with ISO 8504-2 and subsequent parts of ISO 8504 that describe particular surface preparation methods. -,-,- INTERNATIONAL STANDARDISO 8504-1:2000(E) ISO 2000 All rights reserved1 Prepar
