At least 5 m of the runway before the barrier shall be level, flat and smooth. 5.1.2 Barrier The barrier is made of reinforced concrete. The front width is not less than 3 m and the height is not less than 1.5 m. Barrier thickness should ensure that its mass is not less than 7 × 104 kg. The front surface of the barrier should be plumb. The normal line should form a 0° angle with the straight direction of the vehicle. And the barrier surface should be covered with a plywood of 20 mm ± 1 mm thickness and in good condition (as shown in Figure 5). 5.1.3 Barrier positioning The orientation of the barrier shall make the angle of impact 0°. Figure 5 0° barrier with plywood 5.1.4 Vehicle conditions 5.1.4.1 General requirements The test vehicle shall be able to reflect the characteristics of the series, shall include all equipment normally installed, and should be in the normal operation state. Some components may be replaced by equivalent mass alternatives, but the requirement for such replacement should not affect the measurement results of 5.6. 5.1.4.2 Vehicle mass 5.1.4.3 Adjustment of passenger compartment 5.1.4.3.1 Steering wheel position If the steering wheel is adjustable, it shall be adjusted to the position specified by the manufacturer. If not specified by the manufacturer, it should be adjusted to the middle of the adjustable range. At the end of the acceleration process, the steering wheel should be in a free state, and in the position specified by the manufacturer when the vehicle is running straight. 5.1.4.3.2 Glass The moving glass on the vehicle should be in the closed position.

If the pedal is adjustable, it should be placed in the middle position, unless the manufacturer has special requirements for this position. 5.2 Dummy 5.2.1 In accordance with the provisions of Annex C, in each front seat on the outside, place a dummy that meets the requirements, the dummy should meet 50% of Hybrid III dummy technical requirements and the corresponding adjustment requirements. In order to record the necessary data so as to determine the performance indicators, the dummy shall be equipped with a measuring system complying with the technical requirements of Annex D. 5.2.2 During the test, it shall use the restraint system set by the manufacturer. 5.3 Vehicle driving 5.3.1 Vehicles should not be driven by their own power. 5.4 Test speed 5.5 Measurement of front seat dummy 5.5.1 In order to determine all measurements required by performance indicators, it shall use the measurement system which complies with requirements of Annex D. 5.5.2 The different parameters shall be recorded by means of an independent data channel with the following CFC (channel frequency class). 5.6 Measurements made on vehicle 5.6.1 During the simplified test specified in Annex E, the deceleration time history of the torso structure shall be determined on the basis of the reading of the longitudinal acceleration sensor at the lower end of the "B" column on the left side of the vehicle. Use a data channel that complies with Annex D and has a CFC of 180. 5.6.2 The speed-time curve used in the simplified test procedure specified in Annex E shall be obtained from the longitudinal acceleration sensor at the lower end of the "B" column on the left side of the vehicle.6 Vehicle type change and expansionAny changes in the position of the vehicle controls or mechanical components that affect the structure, number of seats, interiors or equipment, or which may affect the energy absorption characteristics of the front of the vehicle, shall be notified to the competent vehicle authority. The competent vehicle department shall take one of the following measures.7 Transition period requirements of standardimplementation 7.1 For the new application type approval model, it shall be implemented after 1 year since the date of publication of this Standard.
