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 21487 was prepared by Technical Committee ISO/TC 188, Small craft.

4 General properties
4.1 Resistance to liquids in contact
4.1.1 All seals such as gaskets, o-rings and joint-rings shall be of non-wicking, i.e. non-fuel absorbent,
material.
4.1.2 All materials used shall be resistant to deterioration by the fuel for which the system is designed and
to other liquids or compounds with which the material can come in contact as installed under normal operating
conditions, e.g. grease, lubricating oil, bilge solvents and sea water.
4.1.3 The melting point of materials used for manufacturing of plastic fuel tanks shall be higher than 150 °C.
4.2 Copper-based alloys
Copper-based alloys for fittings are acceptable for direct coupling with all tank materials specified in Table 1,
except aluminium. Copper-based alloy fittings are allowed for aluminium tanks only if a galvanic barrier is
arranged between fitting and tank.
4.3 Provisions to tanks
4.3.1 Provisions shall be made to enable the fuel level or quantity in the tank to be determined.
4.3.2 Metal tanks shall be designed or installed so that no exterior surface will trap water.
4.3.3 Rigid fuel suction tubes and fill pipes which extend near the tank bottom shall have sufficient
clearance to prevent contact with the bottom during normal operation of the craft.
4.3.4 All non-integral tank supports, chocks or hangers shall either be separated from the surface of metal
tanks by a non-metallic, non-hygroscopic, non-abrasive material or welded to the tank.
4.3.5 If baffles are provided, the total open area provided in the baffles shall be not greater than 30 % of the
tank cross section in the plane of the baffle.
4.3.6 Baffle openings shall be designed so that they do not prevent the fuel flow across the bottom or trap
vapour across the top of the tank.
4.3.7 The fuel fill pipe on the tank shall have a minimum inside diameter of 31,5 mm.
4.3.8 Each ventilation pipe on the tank shall have a minimum inside diameter of 11 mm (95 mm ).
4.3.9 Suitable metallic tank materials and minimum recommended material thicknesses required for
corrosion resistance are given in Table 1. Other materials may be used if they demonstrate equivalent fuel
and corrosion resistance.

4.4 Petrol fuel tanks
Petrol fuel tanks shall comply with the requirements of Clause 5.
4.5 Diesel fuel tanks
Diesel fuel tanks shall comply with the requirements of Clause 6.
4.6 Installation of non-integral tanks
4.6.1 Tank mechanical fixing
Non-integral tanks shall be installed so that the loads due to the mass of the full tank are safely introduced into
the structure, with due consideration given to upward and downward acceleration due to the craft's
movements at maximum speed in the sea. In this respect, continuous flexible supports spreading loads are
preferable to rigid ones.
Metal or textile hold-down straps are considered as a good practice provided that chafe and corrosion are kept
to a minimum.
4.6.2 Other installation requirements
For other installation requirements (filling, vent lines, fuel circuit, etc.), ISO 10088 applies.
5 Petrol fuel tanks: design and tests
5.1 Design
5.1.1 Petrol fuel tanks shall not be integral with the hull.
5.1.2 Petrol fuel tanks shall have all fittings and openings on top, except metallic fill and ventilation pipes,
which may be connected to the sides or ends of metal petrol fu
