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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17338 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 1, Lifesaving and fire protection.
Introduction
This International Standard provides standard illustrations and methods of preparation for drawings for fire
protection of ships and high-speed craft provided by thermal and structural boundaries (divisions). It may be
applied equally to drawings for existing ships and high-speed craft, and for ships and high-speed craft under
[3]
construction. This International Standard is complementary to ISO 17631 , which specifies plans primarily
for use by ship operators, and shipboard and shore-side fire-fighting personnel, in responding to shipboard
emergencies. This International Standard specifies drawings primarily for use by shipbuilders and regulatory
authorities to specify and audit the system of thermal and structural boundaries to provide fire protection on a
ship or high-speed craft as required by applicable national and international regulations.

1 Scope
This International Standard specifies the design and layout of drawings for indicating the fire rating of thermal
and structural boundaries (divisions) for fire protection of ships.
