22、0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical co

23、mmittee has been established has the right to be represented on that committee. International organizations, governmental and non- governmental, in liaison with SO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electro

24、technical standardization. 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. International Standard IS0 12944-1 was prepare

25、d by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14, Corrosion protection of steel structures by protective paint systems. IS0 12944 consists of the following parts, under the general title Paints and varnishes - Corrosion protection of steel structures by protective paint s

28、hat may lead to damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand the corrosion stresses during the service life required of the structure. There are different ways of protecting steel structures from corrosion. IS0 12944 deals with protection by pain

29、t 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 structures, it

30、 is necessary for owners of such structures, planners, consultants, companies carrying out corrosion protection work, inspectors of protective coatings and manufacturers of coating materials to have at their disposal state-of- the-art information in concise form on corrosion protection by paint syst

31、ems. Such information has to be as complete as possible, unambiguous and easily understandable to avoid difficulties and misunderstandings between the parties concerned with the practical implementation of protectinn work. This International Standard - IS0 12944 - is intended to give this informatio

32、n in the form of a series of instructions. It is written for those who have some technical knowledge. It is also assumed that the user of IS0 12944 is familiar with other relevant International Standards, in particular those dealing with surface preparation, as well as relevant national regulations.

33、 Although IS0 12944 does not deal 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 this standard may result in serious financial co

34、nsequences. !SO 12944-1 defines the overall scope of all parts of IS0 12944. It gives some basic terms and definitions and a general introduction to the other parts of IS0 12944. Furthermore, it includes a general statement on health, safety and environmental protection, and guidelines for using IS0

35、 12944 for a given project.

Other protective functions, like the I - I - microorganisms (marine fouling, bacteria, fungi, etc.), = * - chemicals (acids, alkalis, organic solvents, gases,

37、etc.), m * - mechanical action (abrasion, etc.) and are not cowered by IS0 12944. 1.3 The field-of application is characterized by: - the type of structure, - the type of surface and surface preparation, - the type of environment, - the type of protective paint system, - the type of work and - the d

38、urability of the protective paint system. Although IS0 12944 does not cover ail types of structure, surface and surface preparation, it may, by agreement, also be applied to those cases which are not covered by the standard.

40、trength calculation. Not covered by IS0 12944 are concrete structures reinforced with steel. 1.3.2 Type of surface and surface preparation IS0 12944 deals with the following types of surface consisting of carbon or low-alloy steel, and their preparation: - uncoated surfaces: - surfaces thermally spr

41、ayed with zinc, aluminium or their alloys; - hot-dip-galvanized surfaces; - zinc-electroplated surfaces; - sherardized surfaces; - surfaces painted with prefabrication primer; - other painted surfaces. 1.3.3 Type of environment IS0 12944 deals with: - six corrosiviy categories for atmospheric enviro

42、nments, - three categories for structures immersed in water or buried in soil. 1.3.4 Typ of protective paint system IS0 12944 covers a range of paint products which dry or cure at ambient conditions. Not covered by IS0 12944 are: - powder coating materials, - stoving enamels, - heatcured paints, - c

43、oatings of more than 2 mm dry-film thickness, - linings of tanks, - products for the chemical treatment of surfaces (e.g. phosphating solutions). 1.3.5 Typ of work IS0 12944 covers both new work and maintenance. 2 STD.BSI BS EN IS0 LZqqq-L-ENGL 1998 Lb2qbbl 0738252 5b7 e EN IS0 12944-1:1998 1.3.6 Du
