ISO 12944-1:2017(E)

Introduction Unprotected steel in the atmosphere, in water and in soil is subjected to corrosion that can lead to damage. Therefore, 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 protection 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 effect ive corrosion protect ion of steel structures, owners of such struct ures, 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 systems. It is vital that such information is as complete as possible, unambiguous and easily understandable to avoid dificulties and misunderstandings between the parties concerned with the practical implementation of protection work. I S B © , y p o C d e l l o r t n o c n U

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 knowledge. It is also assumed that the user of ISO 12944 (all parts) is familiar w ith other relevant International Standards, in part icular those dealing with surface preparation.

Although ISO 12944 (all parts) does not deal with inancial 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 inancial consequences.

BS EN ISO 12944-1:2017

ISO 12944-1:2017(E)

4.3.7

Durability of the protective paint system

ISO 12944 (all parts) considers four different durability ranges (i.e. low, medium, high, and very high). See 3.5 and Clause 5. The durability range is not a “guarantee time”.

5

General considerations and requirements

5.1 Since the durability of a protective system is normally assumed to be shorter than the expected service life of the structure, additional considerations shall be given at the planning and design stage to the possibility of their maintenance or (partial or total) refurbishment.

Sample areas provide guidance on the type of refurbishment and can also be used for the assessment of the visual appearance.


5.2 Structural components which are exposed to corrosion stresses and which are no longer accessible for corrosion protection measures after assembly shall be provided with corrosion protection that will remain effective, and hence ensure the stability of the structure, for the duration of the service life of the structure. If this cannot be achieved by means of protective coating systems, other measures shall be taken (for example, manufacturing components from corrosion-resistant material, designing components so that they are replaceable or the speciication of a corrosion allowance). 5.3 The cost-effectiveness and sustainability of a given corrosion protection system will generally be in direct proportion to the length of time for which effective protection is maintained, since the amount of maintenance or replacement work required during the service life of the structure will be reduced to a minimum. 5.4 The type of environmental conditions ( 4.3.4) and the durability of coatings systems ( 5.5) are the main parameters for selecting the coating systems. 5.5 The level of coating failure before the irst major maintenance painting shall be agreed upon by the interested parties and shall be assessed in accordance with ISO 4628-1, ISO 4628-2, ISO 4628-3, ISO 4628-4 and ISO 4628-5, unless otherwise agreed between the interested parties.

For example, the irst major maintenance painting would normally need to be carried out for reasons of corrosion protection once about 10 % of the coatings have reached Ri 3, as deined in ISO 4628-3. This requirement may be applied to the whole structure or to representative sections as agreed upon between involved parties, which may then be classiied separately. In this document, durability is expressed in terms of four ranges: — low (L) up to 7 years; — medium (M) 7 years to 15 years; — high (H) 15 years to 25 years; — very high (VH) more than 25 years. The durability range is not a “guarantee time”. Durability is a technical consideration/planning parameter that can help the owner set up a maintenance programme. A guarantee time is a consideration that is the legal subject of clauses in the administrative part of the contract. The guarantee time is usually shorter than the durability range. There are no rules that link the two periods of time.

6 Health and safety and environmental protection It is the duty of clients, speciiers, contractors, paint manufacturers, inspectors and all other personnel involved in a project to carry out the work for which they are responsible in such a manner that they do not endanger the health and safety of themselves or others. Items that will need particular attention are, for example, as follows:

— not specifying or using toxic or carcinogenic substances; — emissions of volatile organic compounds (VOCs);

— measures against harmful effect s of fumes, dust, vapours and noise, as well as ire hazards; — protection of the body, including the eyes, the skin, the ears and the respiratory system; — protection of water and soil during corrosion protection work; — recycling of materials and waste disposal.

7.1 ISO 12944-2 describes the corrosion stresses produced by the atmosphere, by different types of water and by soil. It deines atmospheric-corrosivity categories and indicates the corrosion stresses to be expected in situations where steel structures are immersed in water or buried in soil. The corrosion stresses to which a steel structure is exposed represent one essential parameter governing the selection of appropriate protective paint systems in accordance with ISO 12944-5.

7.2 ISO 12944-3 gives information on basic design criteria for steel structures for the purpose of improving their resistance to corrosion. It gives examples of suitable and unsuitable designs, indicating, with the help of diagrams, which structural elements and combinations of elements are likely to cause accessibility problems during surface preparation work and when applying, inspecting and maintaining paint systems. In addition, design features which facilitate the handling and transport of steel structures are discussed. 7.3 ISO 12944-4 describes different types of surface to be protected and gives information on mechanical, chemical and thermal surface preparation methods. It deals with surface preparation grades, surface proile (roughness), assessment of prepared surfaces, temporary protection of prepared surfaces, preparation of temporarily protected surfaces for further coatings, preparation of existing metal coatings, and environmental aspects. As far as possible, reference is made to the basic International Standards on the surface preparation of steel substrates before application of paints and related products. ISO 129444 is intended to be read in conjunction with ISO 12944-5 and ISO 12944-7. 7.4 ISO 12944-5 describes different generic types of paints on the basis of their chemical composition and the type of ilm formation process. It gives examples of various protective paint systems that have proved suitable for structures exposed to corrosive stresses and corrosivity categories described in ISO 12944-2, relecting current knowledge on a world-wide scale. ISO 12944-5 is intended to be read in conjunction with ISO 12944-6. 7.5 ISO 12944-6 speciies laboratory test methods that are to be used when the performance of protective paint systems is to be assessed. It is particularly intended for paint systems for which suficient practical experience is not yet available and covers testing of paint systems designed for application to steel prepared by blast-cleaning, to hot-dip-galvanized steel and to thermally sprayed metallic coatings. Atmospheric environments and immersion in water (fresh, brackish or sea water) are also covered. 7.6 ISO 12944-7 describes how paint work is to be carried out in the workshop or on site. It describes methods for the application of coating materials. Handling and storage of coating materials before 6

application, inspection of the work and follow-up of the resulting paint system, as well as preparation of reference areas, are also covered. It does not cover surface preparation work (see ISO 12944-4). 7.7 ISO 12944-8 gives guidance for developing speciications for corrosion protection work, describing everything that has to be taken into account when a steel structure is to be protected against corrosion. For the convenience of the user, ISO 12944-8 distinguishes between project speciication, paint system speciication, paint work speciication, and inspection and testing speciication. Various annexes deal with particular aspects such as planning of the work, reference areas and inspection, and offer models of forms intended to facilitate the work. 7.8 ISO 12944-9 describes requirements, test methods and assessment criteria for protective systems under offshore and related conditions, classiied as categories CX and Im4. ISO 12944-9 deals only with the offshore part of the CX category. Requirements, test methods and acceptance criteria for other extreme corrosive stresses included in category CX are agreed upon separately between the interested parties.

Annex A (informative) Guidelines for using ISO 12944 (all parts) for a given project

In order to ensure effective corrosion protection, it is important that suitable speciications are written for the project (see ISO 12944-8), taking the following items as the basis: a)

analyse or estimate the corrosivity of the environment in the area where the structure is located or is to be located (see ISO 12944-2);

b)

establish any special conditions which may affect the choice of paint system to be used (see ISO 12944-5);

c)

examine the design of the struct ure and make sure that corrosion traps have been avoided and adequate access has been provided for corrosion protection work; avoid galvanic corrosion by insulating dissimilar metals from each other (see ISO 12944-3);

I S B © , y p o C d e l l o r t n o c n U , 8 1 0 2 / 5 0 / 7 0

d) for maintenance painting , assess the condition of the surface to be treated (see ISO 12944-4);

e)

identify those paint systems with the required durability from those listed as being suitable for the relevant environment (see ISO 12944-5), or from results of laboratory performance testing, if no long-term experience is available (see ISO 12944-6);

f)
