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.
The procedures used to 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 the 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 during the development of the document will be in the Introduction and/or

ISO 12944-7:2017(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 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 (all parts) for a given
project.
This document describes how paint work on steel structures is to be executed and supervised after
the surface has been prepared in accordance with ISO 12944-4. Examples of protective paint systems
suitable for this purpose are given in ISO 12944-5.
