PART I — APPROVAL OF VEHICLES WITH REGARD TO THEIR FUEL TANKS
4. DEFINITIONS
For the purposes of this Part of the Regulation:
4.1.
‘approval of a vehicle’ means the approval of a vehicle type with regard to the liquid fuel tanks;
4.2. ‘vehicle
type’
means
vehicles
which
do
not
differ
in
such
essential
respects
as:
4.2.1. the
manufacturer’s
type
designation;
4.2.2. in
vehicles
of
category
M1
( 1 ) the position of the tank(s) in the vehicle in so far as it has a
negative effect on the requirements of paragraph 5.10;
4.3. ‘passenger
compartment’
means
the
space
for
occupant
accommodation
bounded
by
the
roof,
floor, side walls, doors, outside glazing, front bulkhead, and the plane of the rear compartment
bulkhead or the plane of the rear seat back support;
4.4.
‘tank’ means the tank(s) designed to contain the liquid fuel, as defined in paragraph 4.6, used
primarily for the propulsion of the vehicle excluding its accessories (filler pipe, if it is a separate
element, filler hole, cap, gauge, connections to the engine or to compensate interior excess
pressure, etc.;
4.5.
‘capacity of the fuel tank’ means the fuel tank capacity as specified by the manufacturer; and
4.6.
‘liquid fuel’ means a fuel which is liquid in normal conditions of temperature and pressure.
5. REQUIREMENTS
FOR
LIQUID
FUEL
TANKS
5.1. Tanks
shall
be
made
so
as
to
be
corrosion-resistant.
5.2. Tanks
shall
satisfy,
when
equipped
with
all
accessories,
which
are
normally
attached
to
them,
the
leakage tests carried out according to paragraph 6.1 at a relative internal pressure equal to double
the working overpressure, but in any event not less than an overpressure of 0,3 bar.
Tanks made of a plastic material are considered as meeting this requirement if they have passed
the test described in Annex 5, paragraph 2.
5.3.
Any excess pressure or any pressure exceeding the working pressure shall be compensated
automatically by suitable devices (vents, safety valves, etc.).
5.4. The
vents
shall
be
designed
in
such
a
way
as
to
prevent
any
fire
risk.
In
particular,
any
fuel,
which may leak when the tank(s) is (are) being filled shall not be able to fall on the exhaust
system. It shall be channelled to the ground.
5.5.
The tank(s) shall not be situated in, or form, a surface (floor, wall, bulkhead) of the passenger
compartment or other compartment integral with it.
5.6.
A partition shall be provided to separate the occupant compartment from the tank(s). The
partition may contain apertures (e.g. to accommodate cables) provided they are so arranged
that fuel cannot flow freely from the tank(s) into the occupant compartment or other
compartment integral with it during normal conditions of use.
5.7.
Every tank shall be securely fixed and so placed as to ensure that any fuel leaking from the tank
or its accessories will escape to the ground and not into the occupant compartment during
normal conditions of use.

5.8.
The filler hole shall not be situated in the occupant compartment, in the luggage compartment or
in the engine compartment.
5.9.
The fuel shall not escape through the tank cap or through the devices provided to compensate
excess pressure during the foreseeable course of operation of the vehicle. In the case of over
turning of the vehicle, a drip may be tolerated provided that it does not exceed 30 g/min; this
requirement shall be verified during the test prescribed in paragraph 6.2.
5.9.1.
The fuel filler cap shall be fixed to the filler pipe.
5.9.1.1. The
requirements
of
paragraph
5.9.1
shall
be
deemed
to
be
satisfied
if
provision
is
made
to
prevent excess evaporative emissions and fuel spillage caused by a missing fuel filler cap.
This may be achieved using one of the following:
5.9.1.1.1. an automatically opening and closing, non–removable fuel filler cap;
5.9.1.1.2. design features which avoid excess evaporative emissions and fuel spillage in the case of a missing
fuel filler cap;
5.9.1.1.3. any other provision which has the same effect. Examples may include, but are not limited to, a
tether filler cap, a chained filler cap or one utilising the same locking key for the filler cap and for
the vehicle’s ignition. In this case, the key shall be removable from the filler cap only in the
locked condition. However, the use of tethered or chained filler cap by itself is not sufficient for
vehicles other than those of categories M1 and N1.
5.9.2.
the seal between the cap and the filler pipe shall be retained securely in place. The cap shall latch
securely in place against the seal and filler pipe when closed.
5.10.
Tanks shall be installed in such a way as to be protected from the consequences of a collision to
the front or the rear of the vehicle; there shall be no protruding parts, sharp edges, etc. near the
tank.
5.11.
The fuel tank and its accessory parts shall be designed and installed in the vehicle in such a way
that any ignition hazard due to static electricity shall be avoided. If necessary, measure(s) for
charge dissipation shall be provided. The manufacturer shall demonstrate to the technical service
the measure(s) which guarantee the fulfilling of these requirements.
5.12.
The fuel tank(s) shall be made of a fire-resistant metallic material. It (they) may be made of a
plastic material provided the requirements of Annex 5 are complied with.
6. TESTS
OF
LIQUID
FUEL
TANKS
6.1. Hydraulic
test
The tank shall be subjected to a hydraulic internal pressure test which shall be carried out on an
isolated unit complete with all its accessories. The tank shall be completely filled with a non-
flammable liquid (water, for example). After all communication with the outside has been cut off,
the pressure shall be gradually increased, through the pipe connection through which fuel is fed
to the engine, to a relative internal pressure equal to double the working pressure used and in any
case to not less than an excess pressure of 0,3 bar (30 kPa), which shall be maintained for one
minute. During this time the tank shell shall not crack or leak; however, it may be permanently
deformed.
6.2. Overturn
test
6.2.1.
The tank and all its accessories shall be mounted on to a test fixture in a manner corresponding
to the mode of installation on the vehicle for which the tank is intended: this also applies to
systems for the compensation of the interior excess pressure.
6.2.2.
The test fixture shall rotate about an axis lying parallel to the longitudinal vehicle axis.
6.2.3.
The test shall be carried out with the tank filled to 90 per cent of its capacity and also 30 per
cent of its capacity with a non-flammable liquid having a density and a viscosity close to those of
the fuel normally used (water may be accepted).

6.2.4.
The tank shall be turned from its installed position 90° to the right. The tank shall remain in this
position for at least five minutes. The tank shall then be turned 90° further in the same direction.
The tank shall be held in this position, in which it is completely inverted, for at least another five
minutes. The tank shall be rotated back to its normal position. Testing liquid that has not flowed
back from the venting system into the tank shall be drained and replenished if necessary. The
tank shall be rotated 90° in the opposite direction and left for at least five minutes in this
position.
The tank shall be rotated 90° further in the same direction. This completely inverted position
shall be maintained for at least five minutes. Afterwards the tank shall be rotated back to its
normal position.
The rotation rate for each successive increment of 90° shall take place in any time interval from 1
to 3 minutes.

ANNEX 5
TESTING OF FUEL TANKS MADE OF A PLASTIC MATERIAL
1. COLLISION
RESISTANCE
1.1. The
tank
shall
be
filled
to
its
capacity
with
a
water-glycol
mixture
or
with
another
liquid
having
a
low
freezing
point, which does not change the properties of the tank material, and shall then be subjected to a perforation test.
1.2. During this test the tank temperature shall be 233K ± 2K (– 40 °C ± 2 °C).
1.3. A pendulum collision testing fixture shall be used for the test. The collision body shall be of steel and have the
shape of a pyramid with equilateral-triangle faces and a square base, the summit and the edges being rounded to a
radius of 3 mm. The centre of percussion of the pendulum shall coincide with the centre of gravity of the pyramid;
its distance from the axis of rotation of the pendulum shall be 1 m. The total mass of the pendulum shall be
15 kg. The energy of the pendulum at the moment of collision shall be not less than 30 Nm and as close to that
value as possible.
1.4. The tests shall be made on the points of the tank which are regarded as vulnerable to frontal or rear collisions. The
points regarded as vulnerable are those which are most exposed or weakest having regard to the shape of the tank
or the way in which it is installed on the vehicle. The points selected by the laboratories shall be indicated in the
test report.
1.5. During the test, the tank shall be held in position by the fittings on the side or sides opposite the side of collision.
No leak shall result from the test.
1.6. At the choice of the manufacturer, all the impact tests may be carried out on one tank or each may be carried out
on a different tank.
2. MECHANICAL
STRENGTH
The tank shall be tested under the conditions prescribed in paragraph 6.1 of this Regulation for leaks and for
rigidity of shape. The tank and all its accessories shall be mounted onto a test fixture in a manner corresponding to
the mode of installation on the vehicle for which the tank is intended or mounted in the vehicle itself or mounted
in a test fixture made by a vehicle section. On request of the manufacturer and with the agreement of the technical
service the tank may be tested without using any test fixture. Water at 326 K (53 °C) shall be used as the testing
fluid and shall fill the tank to its capacity. The tank shall be subjected to a relative internal pressure equal to double
the working pressure and in any case to not less than 30 kPa at a temperature of 326 K ± 2 K (53 °C ± 2 °C) for a
period of 5 hours. During the test, the tank and its accessories shall not crack or leak; however, it may be
permanently deformed.
3. FUEL
PERMEABILITY
3.1. The fuel used for the permeability test shall be either the reference fuel specified in Regulation No 83, Annex 9 or
a commercial premium-grade fuel. If the tank is only designed for installation on vehicles with a compression-
ignition engine, the tank shall be filled with diesel fuel.
3.2. Prior to the test, the tank shall be filled to 50 per cent of its capacity with testing fuel and stored, without being
sealed, at an ambient temperature of 313 K ± 2 K (40 °C ± 2 °C) until the weight loss per unit time becomes
constant, but for not more than 4 weeks (preliminary storage time).
3.3. The tank shall then be emptied and refilled to 50 per cent of its capacity with test fuel, after which it shall be
hermetically sealed and be stored at a temperature of 313 K ± 2 K (40 °C ± 2 °C). The pressure shall be adjusted
when the contents of the tank have reached the testing temperature. During the ensuing test period of 8 weeks, the
loss of weight due to diffusion during the test period shall be determined. The maximum permissible average loss
of fuel is 20 g per 24 hours of testing time.
3.4. If the loss due to diffusion exceeds the value indicated in paragraph 3.3, the test described there shall be carried
out again, on the same tank, to determine the loss by diffusion at 296 K ± 2 K (23 °C ± 2 °C) but under the same
conditions otherwise. The loss so measured shall not exceed 10 g per 24 hours.
4. RESISTANCE
TO
FUEL
After the test referred to in paragraph 3, the tank shall still meet the requirements set out in paragraphs 1 and 2.

5. RESISTANCE
TO
FIRE
The tank shall be subjected to the following tests.
5.1. For two minutes, the tank, fixed as on the vehicle, shall be exposed to flame. There shall be no leakage of liquid
fuel from the tank.
5.2. Three tests shall be made on different tanks filled with fuel as follows:
5.2.1. if the tank is designed for installation on vehicles equipped with either a positive ignition engine or a compression
ignition engine, three tests shall be carried out with tanks filled with premium-grade gasoline;
5.2.2. if the tank is only designed for installation on vehicles equipped with a compression-ignition engine, three tests
shall be carried out with tanks filled with diesel fuel;
5.2.3. for each test the tank and its accessories shall be installed in a testing fixture simulating actual mounting
conditions as far as possible. The method whereby the tank is fixed in the fixture shall correspond to the
relevant specifications for its installation. In the case of tanks designed for a specific vehicle use, vehicle parts
which protect the tank and its accessories against exposure to flame or which affect the course of the fire in any
way, as well as specified components installed on the tank and plugs shall be taken into consideration. All
openings shall be closed during the test, but venting systems shall remain operative. Immediately prior to the
test the tank shall be filled with the specified fuel to 50 per cent of its capacity.
5.3. The
flame
to
which
the
tank
is
exposed
shall
be
obtained
by
burning
commercial
fuel
for
positive-ignition
engines
(hereafter called ‘fuel’) in a pan. The quantity of fuel poured into the pan shall be sufficient to permit the flame,
under free-burning conditions, to burn for the whole test procedure.
5.4. The pan dimensions shall be chosen so as to ensure that the sides of the fuel tank are exposed to the flame. The
pan shall therefore exceed the horizontal projection of the tank by at least 20 cm, but not more then 50 cm. The
sidewalls of the pan shall not project more than 8 cm above the level of the fuel at the start of the test.
5.5. The pan filled with fuel shall be placed under the tank in such a way that the distance between the level of the fuel
in the pan and the tank bottom corresponds to the design height of the tank above the road surface at the unladen
mass (see paragraph 7.4). Either the pan, or the testing fixture, or both, shall be freely movable.
5.6. During phase C of the test, the pan shall be covered by a screen placed 3 cm ± 1 cm above the fuel level.
The screen shall be made of a refractory material, as prescribed in Appendix 2. There shall be no gap between the
bricks and they shall be supported over the fuel pan in such a manner that the holes in the bricks are not
obstructed. The length and width of the frame shall be 2 cm to 4 cm smaller than the interior dimensions of the
pan so that a gap of 1 cm to 2 cm exists between the frame and the wall of the pan to allow ventilation.
5.7. When the tests are carried out in the open air, sufficient wind protection shall be provided and the wind velocity at
fuel-pan level shall not exceed 2,5 km/h. Before the test the screen shall be heated to 308 K ± 5 K (35 °C ± 5 °C).
The firebricks may be wetted in order to guarantee the same test conditions for each successive test.
5.8. The
test
shall
comprise
four
phases
(see
Appendix
1).
5.8.1. Phase A: Pre-heating (Figure 1)
The fuel in the pan shall be ignited at a distance of at least 3 m from the tank being tested. After 60 seconds pre-
heating, the pan shall be placed under the tank.
5.8.2. Phase B: Direct exposure to flame (Figure 2)
For 60 seconds the tank shall be exposed to the flame from the freely burning fuel.
5.8.3. Phase C: Indirect exposure to flame (Figure 3)
As soon as phase B has been completed, the screen shall be placed between the burning pan and the tank. The
tank shall be exposed to this reduced flame for a further 60 seconds.
5.8.4. Phase D: End of test (Figure 4)
The burning pan covered with the screen shall be moved back to its original position (phase A). If, at the end of
the test, the tank is burning, the fire shall be extinguished forthwith.

5.9. The results of the test shall be considered satisfactory if no liquid fuel is leaking from the tank.
6. RESISTANCE
TO
HIGH
TEMPERATURE
6.1. The fixture used for the test shall match the manner of installation of the tank on the vehicle, including the way in
which the tank vent works.
6.2. The tank filled to 50 per cent of its capacity with water at 293 K (20 °C) shall be subjected for 1 hour to an
ambient temperature of 368 K ± 2 K (95 °C ± 2 °C).
6.3. The results of the test shall be considered satisfactory if, after the test, the tank is not leaking or seriously
deformed.
7. MARKINGS
ON
THE
FUEL
TANK
The trade name or mark shall be affixed to the tank; it shall be indelible and clearly legible on the tank when the
latter is installed on the vehicle.
