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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11303 was prepared by Technical Committee ISO/TC 156, Corrosion of metals and
alloys.

INTERNATIONAL STANDARD ISO 11303:2002(E)
Corrosion of metals and alloys — Guidelines for selection of
protection methods against atmospheric corrosion
1 Scope
This International Standard gives guidance on the selection of methods of protection against atmospheric corrosion
of metals and alloys. It is applicable for technical equipment and products made of structural metals and used under
atmospheric conditions. In a rational selection of protection methods, the corrosivity of the atmospheric environments
is one of the important factors. These guidelines use the atmospheric corrosivity classification defined in ISO 9223.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 8044:1999, Corrosion of metals and alloys — Basic terms and definitions
ISO 9223:1992, Corrosion of metals and alloys — Corrosivity of atmospheres — Classification
