be conditioned at a temperature between 15 °C and 25 °C for at least 12 hours without being used. During the dynamic testing of safety-belts or restraint systems, the stopping device shall be at the same temperature as during the calibration test, with a tolerance of ±2 °C. The requirements to be met by the stopping device are given in Annex 8 to this Regulation. Any other device giving equivalent results may be used.
