Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 8: Development of specifications for new work and maintenance (ISO 12944-8:2017)
This document covers the development of specifications for corrosion protection of steel structures
using protective paint systems. It relates to new work and maintenance in the workshop or on site
and is also applicable to the corrosion protection of individual components. This document covers
the corrosion protection of steel structures exposed to different corrosion stresses by environments
such as indoors, open-air and immersion in water or burial in soil, as well as special stresses, due for
example, to medium or high temperatures. The need for different durability ranges is considered.
Steel surfaces that have been hot-dip-galvanized, metal-sprayed, zinc-electroplated or sherardized, and
previously painted steel surfaces, are also covered by this document.
In this document, reference areas for assessing the quality of the corrosion protection work and the
performance of the protective paint systems used are dealt with. This document provides detailed
flow charts for planning new work and maintenance, which are taken into account when writing a
specification.
This document can also be used as a guide if extreme corrosion stresses or high temperatures occur,
or if the protective paint systems are to be used on other substrates, such as non-ferrous metals or
concrete, to define suitable specifications.
Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 8: Erarbeiten von Spezifikationen für Erstschutz und Instandsetzung (ISO 12944-8:2017)
In diesem Dokument wird die Erarbeitung von Spezifikationen für den Korrosionsschutz von Stahlbauten durch Beschichtungssysteme behandelt. Es bezieht sich auf Erstschutz und Instandsetzung, im Werk oder auf der Baustelle, und ist auch auf den Korrosionsschutz von einzelnen Bauteilen anwendbar. In diesem Dokument werden der Korrosionsschutz von Stahlbauten, die unterschiedlichen Korrosionsbelastungen durch Umgebungen, wie z. B. in Innenräumen, im Freien sowie in Wasser oder im Erdreich ausgesetzt sind, sowie Sonderbelastungen, z. B. durch mittlere oder hohe Temperaturen, behandelt. Die Notwendigkeit unterschiedlicher Zeitspannen für die Schutzdauer wird berücksichtigt.
Stahloberflächen, die feuerverzinkt, thermisch gespritzt, galvanisch verzinkt oder sherardisiert wurden sowie bereits zuvor beschichtete Stahloberflächen werden in diesem Dokument ebenfalls erfasst.
In diesem Dokument werden Kontrollflächen zum Bewerten der Qualität der Korrosionsschutzarbeiten und der Leistungsfähigkeit der angewendeten Beschichtungssysteme behandelt. Dieses Dokument enthält detaillierte Fließdiagramme für die Planung von Erstschutz- und Instandsetzungsarbeiten, die beim Erstellen einer Spezifikation berücksichtigt werden sollten.
Dieses Dokument kann auch als Leitfaden zur Festlegung geeigneter Spezifikationen angewendet werden, wenn außergewöhnliche Korrosionsbelastungen oder äußerst hohe Temperaturen auftreten oder wenn die Beschichtungssysteme für andere Untergründe, z. B. Nichteisenmetalle oder Beton, zu verwenden sind.
Peintures et vernis - Anticorrosion des structures en acier par systèmes de peinture - Partie 8: Développement de spécifications pour les travaux neufs et de maintenance (ISO 12944-8:2017)
L'ISO 12944-8 :2017 couvre le développement de spécifications relatives à la protection contre la corrosion des structures en acier au moyen de systèmes de peinture anticorrosion. Elle s'applique aux travaux neufs et à la maintenance en atelier ou sur site, ainsi qu'à la protection contre la corrosion des éléments individuels. L'ISO 12944-8 :2017 couvre la protection anticorrosion des structures en acier exposées à différentes contraintes de corrosion dues à l'environnement ? intérieur, extérieur, immersion dans l'eau ou enfouissement dans le sol ? ainsi qu'à des contraintes spéciales, qu'elles soient dues à des températures moyennes ou élevées. Il prend en considération l'existence de besoins différents en matière de durabilité.
L'ISO 12944-8 :2017 traite également des subjectiles d'acier qui ont été galvanisés au trempé à chaud, revêtus de métal par projection à chaud, électrozingués ou shérardisés, ainsi que des aciers préalablement peints.
Il traite par ailleurs des surfaces de référence permettant d'évaluer la qualité de la protection contre la corrosion et les performances des systèmes de peinture anticorrosion utilisés. L'ISO 12944-8 :2017 propose des logigrammes de planning pour des travaux neufs et de maintenance pour l'élaboration d'une spécification.
L'ISO 12944-8 :2017 peut également servir de guide pour définir des spécifications adaptées en cas de contraintes de corrosion extrêmes ou de températures élevées ou lorsque les systèmes de peinture anticorrosion sont utilisés sur d'autres subjectiles, comme des métaux non-ferreux ou du béton.

ISO 12944-8:2017(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 effective corrosion protection of steel 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 systems. 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 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 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, 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 defines the overall scope of all parts 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 for a given project.
This document is intended as an aid when a corrosion protection specification is to be drawn up.

4 How to develop a specification for new work or maintenance
It is recommended that the specifier considers the information given in Clause 5 and establishes which
specification(s) apply/applies to the project or constituent element to be protected. Then, the specifier
should check in the respective table, item by item, which of the items listed are to be taken into account
in the specification. The various items are supported by detailed information given in the "Remarks"
column in Tables 1 to 4 and in Annexes A to J.
When writing a specification for new work or maintenance, it is important to choose the most suitable
protective paint system. Prior to refurbishment, it can be helpful to create sample areas, e.g. to assess
the coating suitability and appearance. To achieve this, all relevant parameters shall be taken into
consideration, for example:
— required durability;
— environmental conditions and special stresses;
— surface preparation;
— different generic types of paint;
— number and types of coats [priming coat(s), intermediate coat(s) and top coat(s)];
— methods of application and application requirements;
— place of application (shop or site);
— scaffolding requirements;
— requirements regarding (future) maintenance (if any);
— health and safety requirements;
— environmental protection requirements.

SIST EN ISO 12944-8:2018
ISO 12944-8:2017(E)
These parameters are described in detail in ISO 12944-1 to ISO 12944-7 and ISO 12944-9. In this
document, only information which is considered to be particularly important to the specifier is given.
In the drafting of a specification for maintenance work on a structure or constituent element, a decision
needs to be made to choose between
— repair,
— partial renewal, or
— complete renewal.
When complete renewal has been decided on, the specification should preferably be developed in
accordance with a specification for new work, e.g. using the form given in Annex G.
In Annex D, it is shown how to define the work for different types of maintenance work. The exact
definition of which kind of work is necessary shall be decided in dependence of the structure. Test areas
can be useful to find a sufficient solution.
At an early stage in the drafting of a project specification, a final decision will have to be taken by the
specifier on essential planning parameters, such as protection of slip-resistant connections using high-
tensile bolts, the inside surfaces of hollow sections and other hidden steel surfaces (see ISO 12944-3 for
details of design).
Exclusions, i.e. items not to be painted, shall be indicated in the specification(s).
The choice of protective paint systems shall be based on practical experience and/or the results of
laboratory performance tests, particularly when new coating technology is involved. The protective
paint systems shall be tested for compatibility with existing coatings on previously coated surfaces.
The specifier shall further take into account regulations and/or requirements relating to environmental
protection, health and safety, and working conditions in the shop or on site.
5 Contents of a specification
5.1 Supply
The items which are preferably to be covered by a specification are listed in Tables 1 to 4, under the
following headings:
— contents of a project specification (see Table 1);
— contents of a protective paint system specification (see Table 2);
— contents of a paint work specification (see Table 3);
— contents of an inspection and assessment specification (see Table 4).
For small structures, or those whose protection is not subject to any particular requirements, only
certain items shall be taken into account.
NOTE Each table contains sufficient information to enable the specifier to write a specification for any
one of the subjects listed above without having to make frequent references to the other tables. This has led to
some expressions being repeated in each of the tables: for example, under 1.1, 2.1, 3.1 and 4.1, the items “name
of project”, “name of customer” and “name of specifier” are repeated. In practice, such information is to be given
only once in the complete specification.

Foreword
ISO (the International Organization for Standardization) 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 be 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 12944-8 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14,
Protective paint systems for steel structures.
This second edition cancels and replaces the first edition (ISO12944-8:1998), which has been technically
revised.

Introduction
Unprotected steel in the atmosphere, in water and in soil is subjected to corrosion that 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. ISO 12944 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 effective corrosion protection of steel structures, it 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 systems. 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 protection work.
This International Standard – ISO 12944 – 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 is familiar with other relevant International Standards, in particular those dealing with surface
preparation, as well as relevant national regulations.
Although ISO 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 consequences.
ISO 12944-1 defines the overall scope of all parts 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 for a given project.
This part of ISO 12944 is intended as an aid when a corrosion protection specification is to be drawn up.

DRAFT INTERNATIONAL STANDARD ISO/DIS 12944-8:2016(E)
Paints and varnishes — Corrosion protection of steel structures
by protective coating systems — Part 8: Development of
specifications for new work and maintenance
1 Scope
This part of ISO 12944 deals with the development of specifications for corrosion protection of steel
structures, using protective paint systems. It relates to new work and maintenance in the workshop or on site
and is also applicable to the corrosion protection of individual components. This part of ISO 12944 concerns
the corrosion protection of steel structures exposed to different corrosion stresses by environments such as
indoors, open-air and immersion in water or burial in soil, as well as special stresses, for example due to
medium or high temperatures. The need for different durability ranges is considered.
Steel surfaces that have been hot-dip-galvanized, metal-sprayed, zinc-electroplated or sherardized, and
previously painted steel surfaces, are also covered by this part of ISO 12944.
In annex B, reference areas for assessing the quality of the corrosion protection work and the performance of
the protective paint systems used are dealt with. Annexes C and D provide detailed flow charts for planning
new work and maintenance, which should be taken into account when writing a specification.
If extreme corrosion stresses or high temperatures occur, or the protective paint systems are to be used on
other substrates such as non-ferrous metals or concrete, the specifications will have to take this into account.
This part of ISO 12944 may also be used as a guide in such cases.

3.8.1
project specification
specification that describes the project and the requirements relating specifically to it
3.8.2
protective paint system specification:
specification that describes the preparation of the surface of the structure and the protective coating system(s)
for the structure, in conformity with the project specification

3.10
sample area
area on which the properties of a newly applied coating are tested
4 How to develop a specification for new work or maintenance
It is recommended that the specifier considers the information given in clause 5, and establishes which
specification(s) apply/applies to the project or constituent element to be protected. Then, the specifier should
check in the respective table, item by item, which of the items listed are to be taken into account in the
specification. The various items are supported by detailed information given in the "Remarks" column in tables
1 to 4, and in the annexes.
When writing a specification for new work or maintenance, it is important to choose the most suitable
protective paint system. Prior to refurbishment it can be helpful to create sample areas, e.g. to asses the
coating suitability and appearance. To achieve this all relevant parameters shall be taken into consideration,
for example:
required durability;
environmental conditions and special stresses;
surface preparation;
different generic types of paint;
number and types of coats [priming coat(s), intermediate coat(s) and top coat(s)];
methods of application and application requirements;
place of application (shop or site);
scaffolding requirements;
requirements regarding (future) maintenance (if any);

oSIST prEN ISO 12944-8:2016
ISO/DIS 12944-8:2016(E)
health and safety requirements;
environmental protection requirements.
These parameters are described in detail in ISO 12944-1 to ISO 12944-7 and ISO 12944-9. In this part of ISO
12944, only such information is given which is considered to be particularly important to the specifier.
In the drafting of a specification for maintenance work on a structure or constituent element, a decision has to
be taken between
repair,
partial renewal, and
complete renewal.
When complete renewal has been decided, the specification should preferably be developed in accordance
with a specification for new work, e.g. using the form given in annex G.
In Annex D is shown how to define the work for different types of maintenance work. The exact definition
which kind of work is necessary shall be decided in dependence of the structure. Test areas can be useful to
find a sufficient solution.
At an early stage in the drafting of a project specification, a final decision will have to be taken by the specifier
on essential planning parameters, such as protection of slip-resistant connections using high-tensile bolts, the
inside surfaces of hollow sections and other hidden steel surfaces (see ISO 12944-3 for details of design).
Exclusions, i.e. items not to be painted, shall be indicated in the specification(s).
The choice of protective paint systems shall be based on practical experience and/or the results of laboratory
performance tests, particularly when new coating technology is involved. The protective paint systems shall be
tested for compatibility with existing coatings on previously coated surfaces.
The specifier shall further take into account regulations and/or requirements relating to environmental
protection, health and safety, and working conditions in the shop or on site.
Because national requirements concerning health and safety at work, pollution control etc. vary significantly, it
may not be possible to include detailed information covering such requirements in a specification. However,
the specification shall draw attention to the need to comply with current local, regional, national and
international legislation and regulations.
5 Contents of a specification
5.1 Supply
The items which are preferably to be covered by a specification are listed in tables 1 to 4, under the following
headings:
contents of a project specification (Table 1);
contents of a protective paint system specification (Table 2);
contents of a paint work specification (Table 3);
contents of an inspection and assessment specification (Table 4).
NOTE 1 For small structures, or those w hose protection is not subject to any particular requirements, only certain items
need to be taken into account.
An example of a specification based on Table 1 is given as Annex F.

NOTE 2 Each table contains sufficient information to enable the specifier to write a specification for any one of the
subjects listed above without having to make frequent references to the other tables. This has led to some expressions
being repeated in each of the tables, for example under 1.1, 2.1, 3.1 and 4.1 the items "name of project", "name of ow ner"
