Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 11105 was prepared by Technical Committee
tSO/TC 188, Small craft.
This second edition cancels and replaces the first edition
(IS0 11105:1995), definition 3.2, subclauses 4.3.1 and 4.3.2, of which have
been deleted. Additionally, subclause 4.4 and figure 1 have been
amended.

Small craft - Ventilation of petrol engine and/or petrol tank
compartments
1 Scope
This International Standard specifies requirements for ventilation of petrol engine and petrol tank compartments in
small craft of up to 24 m length of hull, having petrol engines for propulsion, electrical generation or mechanical
power, to prevent accumulation of explosive gases in these compartments. Personal watercraft are not covered.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards listed below. Members of IEC and IS0 maintain
registers of currently valid International Standards.

IS0 9097:1991, Small craft - Electric fans.
IS0 11192:- 1 ), Small craft - Graphical symbols.
3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 open to atmosphere: Compartment or space having at least 0,34 m2 of permanent open area directly
exposed to the atmosphere for each cubic metre of net compartment volume.
4 General requirements
4.1 Natural ventilation shall be provided in petrol engine and petrol tank compartments in accordance with
clause 5.
4.2 Powered ventilation shall be provided in petrol engine compartments in accordance with clause 6.
The ventilation duct sizes and airflow requirements shall be calculated based on compartment volumes.

4.4 Compartments containing petrol engines and/or petrol tanks shall be sealed from enclosed accommodation
spaces
Separating structures are regarded as being sealed if they fulfil the following requirements:
a) the boundaries are welded, brazed, glued, laminated or the like;
b) penetrations for cables, piping etc. are closed by fittings and/or sealants;
access openings, for example doors and hatches, are equipped with fittings and are secured.
C>
The effectiveness of the seal can be assessed either by consulting the manufacturer ’s documentation or by visual
inspection during construction.
4.5 No ventilation is required in petrol engine or petrol tank compartments which are open to the atmosphere as
defined in 3.1.
4.6 Neither supply nor exhaust ducts shall open into an accommodation space.
4.7 Electrical components installed in petrol engine and petrol tank compartments and any connecting
compartments, not open to the atmosphere, shall be ignition-protected in accordance with IS0 8846.
5 Natural ventilation systems
5.1 Unless open to the atmosphere, each compartment in a craft shall have a natural ventilation system if
it contains a permanently installed petrol engine; or
electrical component other than the petrol level gauge
- it contains a permanently installed petrol tank and an
sending unit; or
- it is designated to contain a portable petrol tank.
52 . Natural ventilation shall be achieved by an airflow in a compartment by the following:
- a supply opening or duct from the atmosphere; and
- an exhaust opening or duct to the atmosphere.
Each exhaust opening or exhaust duct shall originate in the lower one-third of the compartment.
supply duct and each exhaust opening or exhaust duct in a compartment shall be above the
Each supply opening or
normal accumulation of bilge water.
Compartment air intake and exhaust duct openings shall be separated by at least 600 mm, compartment
dimensions permitting.
5.3 Except as provided in 5.4, the combined area of supply openings or supply ducts, and the combined area of
exhaust openings or exhaust ducts shall have a minimum internal cross-sectional area calculated as follows:
A = 3 300 In (V/0,14)
