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.
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 ISO 12944-8 was prepared by Technical
Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14,
Protective paint systems for steel structures.
ISO 12944 consists of the following parts, under the general title
Paints and varnishes - Corrosion protection of steel structures by
protective paint systems:
Part 1: General introduction
Part 2: Classification of environments
Part 3: Design considerations
Part 4: Types of surface and surface preparation
Part 5: Protective paint systems
Part 6: Laboratory performance test methods
Part 7: Execution and supervision of paint work
Part 8: Development of specifications for new work and
maintenance

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 consise form on
corrosion protection by paint systems. Such information has to be
as complete as possible, unambigous 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.

INTERNATIONAL STANDARD ISO ISO 12944-8:1998(E)
Paints and varnishes – Corrosion protection of steel structures by
protective paint 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.
