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 (4) 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 30 kPa (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 overturning 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. However, no charge dissipation system is required for fuel tanks designed for containing a fuel with a flash point of at least 55 °C as referred to in item 5.1 of the communication form in Annex 1, Appendix 2. Determination of the flash point shall be in accordance with ISO 2719:2002.

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 30 kPa (0,3) bar, 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 3 FRONTAL COLLISION TEST AGAINST A BARRIER 1. PURPOSE AND SCOPE The purpose of this test is to simulate the conditions of frontal collision against a fixed obstacle or by another vehicle approaching from the opposite direction. 2. INSTALLATIONS, PROCEDURES AND MEASURING INSTRUMENTS 2.1. Testing ground The test area shall be large enough to accommodate the run-up track, barrier and technical installations necessary for the test. The last part of the track, for at least 5 m before the barrier, shall be horizontal, flat and smooth. 2.2. Barrier The barrier consists of a block of reinforced concrete not less than 3 m wide in front and not less than 1,5 m high. The barrier shall be of such thickness that it weighs at least 70 tonnes. The front face shall be vertical, perpendicular to the axis of the run-up track, and covered with plywood boards 2 cm thick in good condition. The barrier shall be either anchored in the ground or placed on the ground with, if necessary, additional arresting devices to limit its displacement. A barrier with different characteristics, but giving results at least equally conclusive, may likewise be used. 2.3. Propulsion of vehicle At the moment of collision, the vehicle shall no longer be subject to the action of any additional steering or propelling device. It shall reach the obstacle on a course perpendicular to the collision wall; the maximum lateral misalignment tolerated between the vertical median line of the front of the vehicle and the vertical median line of the collision wall is ± 30 cm. 2.4. State of vehicle 2.4.1. The vehicle under test shall either be fitted with all the normal components and equipment included in its unladen kerb weight or be in such condition as to fulfil this requirement so far as the components and equipment affecting fire risks are concerned. 2.4.2. If the vehicle is driven by external means, the fuel installation shall be filled to at least 90 per cent of its capacity either with fuel or with a non-inflammable liquid having a density and a viscosity close to those of the fuel normally used. All other systems (brake-fluid header tanks, radiator, etc.) may be empty. 2.4.3. If the vehicle is driven by its own engine, the fuel tank shall be at least 90 per cent full. All other liquid-holding tanks may be filled to capacity. 2.4.4. If the manufacturer so requests, the technical service responsible for conducting the tests may allow the same vehicle as is used for tests prescribed by other Regulations (including tests capable of affecting its structure) to be used also for the tests prescribed by this Regulation. 2.5. Velocity on collision The velocity on collision shall be between 48,3 km/h and 53,1 km/h. However, if the test has been carried out at a higher collision velocity and the vehicle has satisfied the conditions prescribed, the test shall be considered satisfactory. 2.6. Measuring instruments The instrument used to record the speed referred to in paragraph 2.5 above shall be accurate to within one per cent. 3. EQUIVALENT TEST METHODS 3.1. Equivalent test methods are permitted provided that the conditions referred to in this Regulation can be observed either entirely by means of the substitute test or by calculation from the results of the substitute test. 3.2. If a method other than that described in paragraph 2 above is used its equivalence shall be demonstrated.

ANNEX 4 PROCEDURE FOR REAR-END COLLISION TEST 1. PURPOSE AND SCOPE 1.1. The purpose of the test is to simulate the conditions of rear-end collision by another vehicle in motion. 2. INSTALLATIONS, PROCEDURES AND MEASURES INSTRUMENTS 2.1. Testing ground The test area shall be large enough to accommodate the impactor (striker) propulsion system and to permit after-collision displacement of the vehicle struck and installation of the test equipment. The part in which vehicle collision and displacement occur shall be horizontal, flat and uncontaminated, and representative of a normal, dry, uncontaminated road surface. 2.2. Impactor (striker) 2.2.1. The impactor shall be of steel and of rigid construction. 2.2.2. The impacting surface shall be flat, not less than 2 500 mm wide, and 800 mm high, and its edges shall be rounded to a radius of curvature of between 40 and 50 mm. It shall be clad with a layer of plywood 20 +/– 2 mm thick, in good condition. 2.2.3. At the moment of collision the following requirements shall be met: 2.2.3.1. The impacting surface shall be vertical and perpendicular to the median longitudinal plane of the vehicle struck; 2.2.3.2. The direction of movement of the impactor shall be substantially horizontal and parallel to the median longitudinal plane of the vehicle struck; 2.2.3.3. The maximum lateral deviation tolerated between the median vertical line of the surface of the impactor and the median longitudinal plane of the vehicle struck shall be 300 mm. In addition, the impacting surface shall extend over the entire width of the vehicle struck; 2.2.3.4. The ground clearance of the lower edge of the impacting surface shall be 175 ± 25 mm. 2.3. Propulsion of the impactor The impactor may either be secured to a carriage (moving barrier) or form part of a pendulum. 2.4. Special provisions applicable where a moving barrier is used 2.4.1. If the impactor is secured to a carriage (moving barrier) by a restraining element, the latter shall be rigid and be incapable of being deformed by the collision; the carriage shall at the moment of collision be capable of moving freely and no longer be subject to the action of the propelling device. 2.4.2. The velocity of collision shall be between 48 km/h and 52 km/h. 2.4.3. The aggregate weight (mass) of carriage and impactor shall be 1 100 ± 20 kg. 2.5. Special provisions applicable where a pendulum is used 2.5.1. The distance between the centre of the impacting face and the axis of rotation of the pendulum shall be not less than 5 m. 2.5.2. The impactor shall be freely suspended by rigid arms rigidly secured to it. The pendulum so constituted shall be substantially incapable of being deformed by the collision. 2.5.3. Arresting gear shall be incorporated in the pendulum to prevent any secondary collision by the impactor on the test vehicle. 2.5.4. At the moment of collision the velocity of the centre of percussion of the pendulum shall be between 48 and 52 km/h. 2.5.5. The reduced mass ‘mr’ at the centre of percussion of the pendulum is defined as a function of the total mass ‘m’, of the distance ‘a’ (1) between the centre of percussion and the axis of rotation, and of the distance ‘l’ between the centre of gravity and the axis of rotation, by the following equation: mr = m (1/a) 2.5.6. The reduced mass mr shall be 1 100 ± 20 kg. 2.6. General provisions relating to the mass and velocity of the impactor If the test has been conducted at a collision velocity higher than those prescribed in paragraphs 2.4.2 and 2.5.4 and/or with a mass greater than those prescribed in paragraphs 2.4.3 and 2.5.6, and the vehicle has met the requirements prescribed, the test shall be considered satisfactory. 2.7. State of vehicle under test 2.7.1. The vehicle under test shall either be fitted with all the normal components and equipment included in its unladen kerb weight or be in such condition as to fulfil this requirement so far as the components and equipment affecting fire risks are concerned. 2.7.2. The fuel tank shall be filled to at least 90 per cent of its capacity either with fuel or with a non-inflammable liquid having a density and a viscosity close to those of the fuel normally used. All other systems (brake-fluid header tanks, radiator, etc.) may be empty. 2.7.3. A gear may be engaged and the brakes may be applied. 2.7.4. If the manufacturer so requests, the following derogation shall be permitted: 2.7.4.1. the technical service responsible for conducting the tests may allow the same vehicle as is used for tests prescribed by other Regulations (including tests capable of affecting its structure) to be used also for the tests prescribed by this Regulation; and 2.7.4.2. The vehicle may be weighted to an extent not exceeding 10 per cent of its unladen kerb weight with additional weights rigidly secured to the structure in such a way as not to affect the behaviour of the structure of the passenger compartment during the test. 2.8. Measuring instruments The instruments used to record the speed referred to in paragraphs 2.4.2 and 2.5.4 above shall be accurate to within one per cent. 3. EQUIVALENT TEST METHODS 3.1. Equivalent test methods are permitted provided that the conditions referred to in this Regulation can be observed either entirely by means of the substitute test or by calculation from the results of the substitute test. 3.2. If a method other than that described in paragraph 2 above is used, its equivalence shall be demonstrated. (1) It is recalled that the distance ‘a’ is equal to the length of the synchronous pendulum under consideration.
