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 13297 was prepared by Technical Committee ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 13297:1995), of which it constitutes a technical
revision.
Annex A and B form a normative part of this International Standard. Annexes C and D are for information only.

Introduction
Annex A specifies conductor requirements. Annex B specifies instructions to be included with the owner's manual
(ISO 10240). Annex C provides information on recommended system tests to be performed upon completion of the
a.c. installation.
Compliance with this International Standard will not, by itself, provide protection against explosion, fire and
electrical shock hazard. The manufacturer also needs to comply with additional standards related to protection
against the same possible hazards. These additional standards are listed in annex D, with a brief description of
their contents. For complete understanding of the requirements, the manufacturer needs to refer to the actual
standard. Compliance with all these International Standards will ensure a high level of safety in all craft, particularly
in those using petrol or liquefied petroleum (LPG).
