Common use of Deceleration test device Clause in Contracts

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.
