22、zation) is a worldwide federation 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 b

23、e represented on that committee. 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.The procedures used t

24、o develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of t

25、he 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 of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified du

28、This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14, Protective paint systems for steel structures.This first edition of ISO 129449 cancels and replaces ISO 20340:2009, which has been technically revised.A list of all parts in the ISO 12944 series ca

Therefore, to avoid corrosion damage, steel structures are normally protected to wit

30、hstand 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 protection by paint systems and covers, in the various parts, all features that are

31、 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 structures, owners of such structures, planners, consultants, companies carrying

32、 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 systems. It is vital that such information is as complete as possible, unambiguous and

33、 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 form of a series of instructions. It is written for those who have some technical kn

34、owledge. 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 deal with financial and contractual questions, attention is drawn to the fact that,

35、 because of the considerable implications of inadequate corrosion protection, non-compliance with requirements and recommendations given in this document may result in serious financial consequences.ISO 129441 defines the overall scope of ISO 12944. It gives some basic terms and definitions and a ge

36、neral 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 project.Offshore and related structures require specific attention in order to be able to withst

37、and the severe corrosion stresses to which they are exposed during their service life and to minimize the risk of failures that would impact safety, operating costs or capital cost.In order to establish sufficient corrosion protection and ensure optimum performance of the coating, it is necessary to

38、 specify the requirements for the protective paint system(s) along with the relevant laboratory performance tests to assess its (their) likely durability.In order to achieve the same performance as indicated by testing, proper surface preparation and application of the paint is essential. Close atte

39、ntion needs to be given to the execution of the work.This document places emphasis on high-durability paint systems, with the aim of minimizing maintenance and hence reducing safety considerations and environmental impact.

41、aint systems for offshore and related structures (i.e. those exposed to the marine atmosphere, as well as those immersed in sea or brackish water). Such structures are exposed to environments of corrosivity category CX (offshore) and immersion category Im4 as defined in ISO 129442.This part of ISO 1

42、2944 describes paint systems for high durability according to ISO 129441.This document is applicable to structures made of carbon steel and does not cover Cd/Bi Cr and Zn/Bi Cr surfaces. It is not applicable to surfaces under insulation or concrete.This document is applicable for paint systems inten

43、ded for a service temperature range between 20 C and +80 C, and the performance testing is aimed at verifying suitability of the paint systems for this temperature range.This document is applicable for paint systems for submerged service (Im4) which are intended for ambient operating temperatures up

44、 to a maximum of 50 C.This document specifies: the test methods to be used to determine the composition of the separate components of the protective paint system; the laboratory performance test methods for the assessment of the likely durability of the protective paint system; the criteria to be us

45、ed to evaluate the results of performance tests.This document covers the requirements for new work and any repairs necessary before startup. It can also be used in relation to maintenance where complete refurbishment is carried out and the underlying metal substrate is completely exposed by abrasive

46、 blastcleaning.It does not address maintenance in general where methods of surface preparation other than abrasive blastcleaning are typically used.This document deals with structures, made of carbon steel of not less than 3 mm thickness, which are designed using an approved strength calculation.The
