Common use of Stopping device Clause in Contracts

Stopping device. 4.1. The device consists of two identical absorbers mounted in parallel. 4.2. If necessary, an additional absorber shall be used for each 200 kg increase in nominal mass. Each absorber shall comprise: 4.2.1. An outer casing formed from a steel tube; 4.2.2. A polyurethane energy-absorber tube; 4.2.3. A polished-steel olive-shaped knob penetrating into the absorber; and 4.2.4. A shaft and an impact plate. 4.3. The dimensions of the various parts of this absorber are shown in the diagram reproduced in Appendix 2 to this Annex. 4.4. The characteristics of the absorbing material are given in table 3 and table 4 of this Annex. 4.5. The stopping device assembly shall be maintained for at least 12 hours at a temperature between 15 ° and 25 °C before being used for the calibration tests described in Annex 7 to this Regulation. The stopping device shall, for each type of test, meet the performance requirements laid down in Annex 7,Appendices 1 and 2. For dynamic tests of an Enhanced child restraint, the stopping device assembly shall be maintained for at least 12 hours at the same temperature, to within ± 2 °C, as that of the calibration test. Any other device giving equivalent results can be accepted.
