This International Standard specifies requirements for ventilation of petrol engine and petrol tank compartments in small craft of up to 24 m lenght 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.

Kleine Wasserfahrzeuge - Belüftung von Räumen mit Ottomotoren und/oder Benzintanks (ISO 11105:1997)

Diese Internationale Norm legt Anforderungen an die Belüftung von Räumen fest, in denen Ottomotoren und Benzintanks auf kleinen Wasserfahrzeugen mit einer Rumpflänge bis 24 m und die Ottomotoren zum Vortrieb, zur Erzeugung elektrischer Energie oder mechanischer Energie dienen, um der Ansammlung von explosiven Gasen vorzubeugen. Private Wasserfahrzeuge sind ausgenommen.

Navires de plaisance - Ventilation des compartiments moteur a essence et/ou réservoir a essence (ISO 11105:1997)

La présente Norme internationale prescrit les exigences de ventilation du compartiment moteur à essence et du compartiment réservoir à essence des navires de plaisance dont la coque ne dépasse pas 24 m de longueur, équipés de moteurs à essence destinés à assurer la propulsion, la production d'électricité ou la puissance mécanique, afin d'empêcher toute accumulation de gaz explosifs dans ces compartiments. Les scooters de mer sont exceptés.

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.

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.

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.

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)
where
is the minimum combined int
