Annex 8
DESCRIPTION OF CURVE OF TROLLEY'S DECELERATION AS A FUNCTION OF TIME
(Curve for testing stopping devices)
Image unavailable in extracted text
The deceleration curve of the trolley weighted with inert mass to produce a total mass of 455 kg + 20 kg for safety‑belt tests and 910 + 40 kg for restraining system tests where the nominal mass of the trolley and vehicle structure is 800 kg must remain within the hatched area above. 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 40 cm + 2 cm. In both the above cases the calibration and measuring procedures shall correspond to those defined in the International Standard ISO 6487:1980; the measuring equipment shall correspond to the specification of a data channel with a channel frequency class (CFC) 60.
