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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

subjected to the greater of the following two values: 20 kPa or 1,5 times the highest hydrostatic
pressure to which the component can be subjected in service.
6.1.4 The fuel system shall be designed to supply fuel to the engine within 10 s of the engine being
energized and automatically stop the supply of fuel within 10 s of the engine being de-energized.
6.2 Fuel tanks
6.2.1 Materials prohibited for fuel tanks
6.2.1.1 A fuel tank shall not be constructed of terneplate.
6.2.1.2 Unless it has an inorganic sacrificial galvanic coating on the inside and outside of the tank, a
fuel tank shall not be constructed of black iron or steel.
6.2.1.3 A metallic fuel tank encased in cellular plastic or in fibre-reinforced plastic shall not be
constructed from a ferrous alloy.
6.2.2 Fuel level indication
A means shall be provided to check the fuel level, or a reserve fuel supply shall be provided.

expansion volume or be equipped with a system that prevents pressure in the tank from exceeding
80 % of the fuel tank design pressure.
6.2.4 Fill and vent openings
Fill and vent openings shall be at or above the liquid level when the tank is filled to its rated capacity
with the personal watercraft in its static floating position.
The vent-line termination or a gooseneck in the vent-line routing shall be arranged at sufficient height
to prevent spillage of fuel through the vent line during filling under normal operating conditions of the
personal watercraft.
6.2.5 Fuel tank static-pressure test
6.2.5.1 A representative fuel tank shall not leak if tested using the procedures specified in 6.2.5.2 and

6.2.5.3 Tank fittings and seams shall be checked for leaks using a method other than the pressure
drop test.
NOTE Soapy test solutions must be non-corrosive and non-toxic. Ammonia, present in some soaps and
detergents, creates a condition that attacks brass fittings like those used in fuel systems. Damage can be
undetectable at first, and these fittings can develop cracks in a matter of months creating a very hazardous
situation.
6.2.6 Fuel tank shock test
6.2.6.1 A representative fuel tank shall not leak when shock tested using the procedures specified in
6.2.6.2 to 6.2.6.7.
6.2.6.2 Confirm that the tank does not leak when pressure tested according to 6.2.5.
6.2.6.3 If the tank is non-metallic, precondition the tank by filling it to capacity with petrol that has
at least a 50 % aromatic content. Keep the fuel in the tank at 21 °C or higher for at least 30 days prior to
testing.
