Furthermore, all structural damage must be contained in the zone ahead of the driver's feet and there must be no damage to the mountings of the safety belts or fire extinguishers. This test must be carried out on the survival cell subjected to the higher loads in the tests described in Articles 15.4.6 and 8, and on a frontal impact absorbing structure subjected to the test described in Article 15.4.7. This test must be carried out in the presence of a FIA technical delegate in an approved testing centre. 4.6. In addition, the survival cell must be subjected to three separate static lateral load tests: 1. In the cockpit area on a vertical plane passing through the centre of the seat belt lap strap fixing. 2. In the fuel tank area on a vertical plane passing through the centre of area of the fuel tank in side elevation. 3. On a vertical plane passing half way between the front wheel axis and the top of the first rollover structure. For the tests described above, a pad 10cm long and 30cm high, with a maximum radius on all edges of 3mm and conforming to the shape of the survival cell, shall be placed against the outermost sides of the survival cell with the lower edge of the pad at the lowest part of the survival cell at that section. Rubber 3mm thick may be used between the pads and the survival cell. A constant transverse horizontal load of 2500daN shall be applied, in less than 3 minutes, to the pads at their centre of area through a ball jointed junction, and maintained for a minimum of 30 seconds. Under these load conditions, there shall be no structural failure of the inner or outer surfaces of the survival cell and permanent deformation must be less than 1.0mm after the load has been released for 1 minute. The deformation will be measured at the top of the pads across the inner surfaces. In test 1, deflection across the inner surfaces of the survival cell must not exceed 2cm. These three tests must be carried out on the survival cell subjected to the impact test described in Article 15.4.5. On every survival cell tested after that one, the same tests must be carried out but with a load of only 2000daN. During the tests the deflection across the inner surfaces must not exceed 120% of the deflection obtained at 2000daN load during the first test. 4.7. To test the attachments of the frontal impact absorbing structure to the survival cell, a static side load test shall be performed on a vertical plane passing 40cm in front of the front wheel axis. A constant transversal horizontal load of 3000daN must be applied to one side of the impact absorbing structure using a pad identical to the ones used in the lateral tests in Article 15.4.6. The centre of area of the pad must pass through the plane mentioned above and the mid point of the height of the structure at that section. After 30 seconds of application, there must be no failure of the structure or of any attachment between the structure and the survival cell. During the test the survival cell must be resting on a flat plate and secured to it solidly but not in a way that could increase the strength of the attachments being tested. 4.8. A further static load test must be carried out on the survival cell from beneath the fuel tank. A pad of 20cm diameter must be placed in the centre of area of the fuel tank and a vertical upwards load of 1250daN applied in less than 3 minutes through a ball jointed junction. The load must be maintained for a minimum of 30 seconds. Under these load conditions, there must be no structural failure of the inner or outer surfaces of the survival cell and permanent deformation must be less than 0.5mm after the load has been released for 1 minute, the measurement being taken at the centre of area of the pad. This test must be carried out on the survival cell subjected to the impact test described in Article 15.4.5. On every survival cell tested after that one, the same test must be carried out but with a load of only 1000daN. During the test the deflection across the inner surfaces must not exceed 120% of the deflection obtained at 1000daN during the first test. 4.9. The static load tests in Articles 15.2.4; 15.4.6; 15.4.7 and 15.4.8 must be carried out in the presence of an FIA technical delegate and using measuring equipment verified by the FIA. For the tests described in Articles 15.4.6 and 15.4.8, the survival cells must always be produced in an identical condition in order that their weights can be compared and if the weight differs by more than 5% from the one submitted to the test described in Article 15.4.5, a further impact test and roll structure test must be carried out. When these tests have been completed, the FIA technical delegate will mark the survival cell. Any significant modification introduced into any of the structures tested shall require that part to undergo a further test. ARTICLE 16: FUEL 1. The only fuel permitted is petrol having the following characteristics: - A minimum of 92 RON and a maximum of 102 RON, measured according to ASTM D 2699-86 and a minimum of 85.0 MON measured according to ASTM D 2700-86. The fuel will be accepted or rejected according to ASTM D 3244 with a confidence limit of 95%. - A maximum of 3.7% oxygen and 0.2% nitrogen by weight, measured by elemental analysis and to ASTM D 3228 respectively. - A maximum of: 5% benzene vol (ASTM D 3606) 700 hPa RVP (ASTM D 323) 0.005 g/L lead (ASTM D 3237) 215 degrees centigrade FBP A density between 725 and 780 kg/m3 at 15 degrees centigrade (ASTM D 4052). And containing no substance capable of exothermic reaction in the absence of external oxygen. 2. Only ambient air may be mixed with the fuel as an oxidant. 3. Petrol within the meaning of this Article is one of the following: 3.1. Petrol of a kind recognised by the FIA as being on general and genuine sale to the public in a country with at least twelve events entered on the International Calendar. 3.2. Petrol consisting solely of substances which can be found in at least one of the various petrols which satisfy (1) above, none of which is present in a greater proportion than in at least one such petrol, and whose proportions of saturates, unsaturates and aromatics do not exceed those found separately or together in at least one such petrol. 3.3. Petrol which does not satisfy 3.1 or 3.2 above. In this case, the petrol in question and each of its components (having regard to the proportions in which such components are present) must be capable of being produced in the quantities and at a cost necessary for bona fide competitive large scale commercial sale to the general public using only known refining, production and storage technology. Such petrol must also satisfy all EEC health and safety regulations and possess no characteristic which would render it unsuitable for sale to the general public. ARTICLE 17: TELEVISION CAMERAS 1. Presence of camera or ballast: All cars must carry an on board camera or a ballast box at all times throughout the event. 2. Location of ballast: The location and position of the ballast box is free. 3. Location of camera and equipment: The position of the on board camera will be determined by the FOCA appointed engineer and approved by the scrutineers. ARTICLE 18: FINAL TEXT The final text for these regulations shall be the English version should any dispute arise over their interpretation.
