barrier propulsion system and to permit after-impact displacement of the vehicle impacted and installation of the test equipment. The part in which vehicle impact and displacement occur shall be horizontal, flat and uncontaminated, and representative of a normal, dry, uncontaminated road surface.

              2. Test conditions

              2.1. The vehicle to be tested shall be stationary.

              2.2. The mobile deformable barrier shall have the characteristics set out in Annex 5 to this Regulation. Requirements for the examination are given in the appendices to Annex 5. The mobile deformable barrier shall be equipped with a suitable device to prevent a second impact on the struck vehicle.

              2.3. The trajectory of the mobile deformable barrier longitudinal median vertical plane shall be perpendicular to the longitudinal median vertical plane of the impacted vehicle.

              2.4. The longitudinal vertical median plane of the mobile deformable barrier shall be coincident within ±25 mm with a transverse vertical plane passing through the R point of the front seat adjacent to the struck side of the tested vehicle. The horizontal median plane limited by the external lateral vertical planes of the front face shall be at the moment of impact within two planes determined before the test and situated 25 mm above and below the previously defined plane.

              2.5. Instrumentation shall comply with ISO 6487:1987 unless otherwise specified in this Regulation.

              2.6. The stabilized temperature of the test dummy at the time of the side impact test shall be 22 ± 4 °C.

              3. Test speed

               The mobile deformable barrier speed at the moment of impact shall be 50 ± 1 km/h. This speed shall be stabilized at least 0.5 m before impact. Accuracy of measurement: 1 per cent. However, if the test was performed at a higher impact speed and the vehicle met the requirements, the test shall be considered satisfactory.

              4. State of the vehicle

              4.1. General specification

               The test vehicle shall be representative of the series production, shall include all the equipment normally fitted and shall be in normal running order. Some components may be omitted or replaced by equivalent masses where this omission or substitution clearly has no effect on the results of the test.

               It shall be allowed by agreement between manufacturer and Technical Service to modify the fuel system so that an appropriate amount of fuel can be used to run the engine or the electrical energy conversion system.

              4.2. Vehicle equipment specification

               The test vehicle shall have all the optional arrangements or fittings likely to influence the results of the test.

              4.3. Mass of the vehicle

              4.3.1. The vehicle to be tested shall have the reference mass as defined in paragraph 2.10. of this Regulation. The mass of the vehicle shall be adjusted
