The work of preparing International Standards is normally carried out thro
28、ugh 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 collabor
29、ates 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 c
30、riteria 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 subject
31、 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade na

34、nd edition cancels and replaces the first edition (ISO 12944-7:1998), which has been technically revised.The main changes compared to the previous edition are as follows: the normative references have been updated; the terms and definitions have been updated; a bibliography has been added; the text
35、has been editorially revised.A list of all parts in the ISO 12944 series can be found on the ISO website.iv ISO 2017 All rights reservedBS EN ISO 129447:2017ISO 12944-7:2017(E)IntroductionUnprotected steel in the atmosphere, in water and in soil is subjected to corrosion that can lead to damage. The
36、refore, to avoid corrosion damage, steel structures are normally protected to withstand the corrosion stresses to which they will be subjected during the service life required of the structure.There are different ways of protecting steel structures from corrosion. ISO 12944 (all parts) deals with pr
37、otection by paint systems and covers, in the various parts, all features that are important in achieving adequate corrosion protection. Additional or other measures are possible but require particular agreement between the interested parties.In order to ensure effective corrosion protection of steel
38、 structures, owners of such structures, planners, consultants, companies carrying out corrosion protection work, inspectors of protective coatings and manufacturers of coating materials need to have at their disposal state-of-the-art information in concise form on corrosion protection by paint syste
39、ms. It is vital that such information is as complete as possible, unambiguous and easily understandable to avoid difficulties and misunderstandings between the parties concerned with the practical implementation of protection work.ISO 12944 (all parts) is intended to give this information in the for
40、m of a series of instructions. It is written for those who have some technical knowledge. It is also assumed that the user of ISO 12944 (all parts) is familiar with other relevant International Standards, in particular those dealing with surface preparation.Although ISO 12944 (all parts) does not de
41、al with financial and contractual questions, attention is drawn to the fact that, because of the considerable implications of inadequate corrosion protection, non-compliance with requirements and recommendations given in ISO 12944 (all parts) can result in serious financial consequences.ISO 12944-1
42、defines the overall scope of ISO 12944. It gives some basic terms and definitions and a general introduction to the other parts of ISO 12944. Furthermore, it includes a general statement on health, safety and environmental protection, and guidelines for using ISO 12944 (all parts) for a given projec
43、t.This document describes how paint work on steel structures is to be executed and supervised after the surface has been prepared in accordance with ISO 12944-4. Examples of protective paint systems suitable for this purpose are given in ISO 12944-5. ISO 2017 All rights reserved vBS EN ISO 129447:20
