Deceleration test device. The trolley shall be so propelled that at the moment of impact its free running speed is 50 km/h ± 1 km/h and the manikin remains stable. The stopping distance of the trolley shall be 40 cm ± 5 cm. The trolley shall remain horizontal throughout deceleration. The deceleration of the trolley shall be achieved by using the apparatus described in Annex 6 to this Regulation or any other device giving equivalent results. This apparatus shall comply with the performance hereafter specified: The deceleration curve of the trolley, weighted with inert mass to produce a total mass of 455 kg ± 20 kg for safety-belts tests and 910 kg ± 40 kg for restraining systems tests where the nominal mass of the trolley and vehicle structure is 800 kg, shall remain within the hatched area of the graph in Annex 8. If necessary, the nominal mass of the trolley and attached vehicle structure can be increased by increments of 200 kg, in which case, an additional inert mass of 28 kg per increment shall be added. In no case shall the total mass of the trolley and vehicle structure and inert masses differ from the nominal value for calibration tests by more than ±40 kg. During calibration of the stopping device, the speed of the trolley shall be 50 km/h ± 1 km/h and the stopping distance shall be of 40 cm ± 2 cm.
Deceleration test device. The deceleration of the trolley shall be achieved by using the apparatus prescribed in Annex 6 to this Regulation or any other device giving equivalent results. This apparatus shall be capable of the performance specified in paragraph 7.1.3.4. below and hereafter specified: Calibration procedure: The deceleration curve of the trolley, in the case of Enhanced Child Restraint System tests performed in accordance with paragraph 7.1.3.1. above, ballasted with inert masses up to 55 kg in order to reproduce one occupied Enhanced Child Restraint System, and in the case of Enhanced Child Restraint System tests in a vehicle body shell performed in accordance with paragraph 7.1.3.2. below, where the trolley is ballasted with the vehicle structure and inert masses up to (x times) 55 kg reproducing the number of (x) occupied Enhanced Child Restraint Systems, shall remain, in the case of frontal impact, within the hatched area of the graph in Annex 7, Appendix 1 to this Regulation, and, in the case of rear impact, within the hatched area of the graph in Annex 7, Appendix 2 to this Regulation. During calibration of the stopping device, the stopping distance shall be 650 ± 30 mm for frontal impact, and 275 ± 20 mm for rear impact. Dynamic testing conditions during testing: For frontal and rear impact the deceleration shall be achieved with the apparatus calibrated as stated above, however:
(a) The deceleration curve shall not have a more than 3 ms time duration exceedance of the lower borders of the performance requirements;
(b) If the tests above were performed at a higher speed and/or the deceleration curve has exceeded the upper level of the hatched area and the Enhanced Child Restraint System meets the requirements, the test shall be considered satisfactory.
Deceleration test device. The deceleration of the trolley shall be achieved by using the apparatus prescribed in Annex 6 to this Regulation or any other device giving equivalent results. This apparatus shall be capable of the performance specified in paragraph 7.1.3.4. and hereafter specified: For frontal impact, the trolley shall be so propelled that, at the beginning of the test, its velocity is 50 + 0/– 2 km/h and its acceleration curve is within the hatched area of the graph in Annex 7, Appendix 1. For rear impact, the trolley shall be so propelled that, at the beginning of the test, its velocity is 30 +2/-0 km/h and its acceleration curve is within the hatched area of the graph in Annex 7, Appendix 2. In addition to fulfilling the above requirements, the Technical Service shall use a mass of trolley (equipped with its seat), as specified in paragraph 1. of Annex 6, greater than 380 kg. However, if the tests above were performed at a higher speed and/or the acceleration curve has exceeded the upper level of the hatched area and the child restraint meets the requirements, the test shall be considered satisfactory. It is however permitted the deceleration curve exceeds the lower boundaries of the performance requirements but for a cumulative period less than 3 ms time;
Deceleration test device. The deceleration of the trolley shall be achieved by using the apparatus prescribed in Annex 6 to this Regulation or any other device giving equivalent results. This apparatus shall be capable of the performance specified in paragraph 8.
1.3.4. and hereafter specified: Calibration procedure: The deceleration curve of the trolley, in the case of child restraint tests performed in accordance with paragraph 8.1.3.1., ballasted with inert masses up to 55 kg in order to reproduce one occupied child restraint, and in the case of child restraint tests in a vehicle body shell performed in accordance with paragraph 8.1.3.2., where the trolley is ballasted with the vehicle structure and inert masses up to x times 55 kg reproducing the number of x occupied child restraint systems, must remain, in the case of frontal impact, within the hatched area of the graph in Annex 7, Appendix 1 of this Regulation, and, in the case of rear impact, within the hatched area of the graph in Annex 7, Appendix 2 of this Regulation. During calibration of the stopping device, the stopping distance shall be 650 ± 30 mm for frontal impact, and 275 ± 20 mm for rear impact.
8.1 3.1.1.3.2. Acceleration test device For frontal impact, the trolley shall be so propelled that, during the test, its total velocity change ΔV is 52 + 0 – 2 km/h and its acceleration curve is within the hatched area of the graph in Annex 7, Appendix 1 and stay above the segment defined by the coordinates (5g, 10ms) and (9g, 20ms). The start of the impact (T0) is defined, according to ISO 17 373 for a level of acceleration of 0.5g. For rear impact, the trolley shall be so propelled that, during the test, its total velocity change ΔV is 32 +2 -0 km/h and its acceleration curve is within the hatched area of the graph in Annex 7, Appendix 2 and stay above the segment defined by the coordinates (5g, 5ms) and (10g, 10ms). The start of the impact (T0) is defined, according to ISO 17 373 for a level of acceleration of 0.5g. Despite the fulfilment of the above requirements, the Technical Service shall use a mass of trolley (equipped with its seat), as specified in paragraph 1. of Annex 6, superior to 380 kg. However, if the tests above were performed at a higher speed and/or the acceleration curve has exceeded the upper level of the hatched area and the child restraint meets the requirements, the test shall be considered satisfactory.
