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

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document 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 (ISO 12944-7:1998), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— the normative references have been updated;
— the terms and definitions have been updated;
— a bibliography has been added;
— the text has been editorially revised.

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.
