a speed of 400 ± 20 mm/min to the geometric centre of the buckle-release button along a fixed axis running parallel to the initial direction of motion of the button. During the application of the force needed to open the buckle, the buckle shall be held by a rigid support. The load quoted above shall not exceed the limit indicated in paragraph 6.2.2.5. above. The point of contact of the test equipment shall be spherical in form with a radius of 2.5 mm ± 0.1 mm. It shall have a polished metal surface.
              7.8.3. The buckle-opening force shall be measured and any failure of the buckle noted.
              7.8.4. After the buckle-opening test, the components of the belt assembly or of the restraint device which have undergone the tests prescribed in paragraph 7.7. above shall be inspected and the extent of the damage sustained by the belt assembly or restraint device during the dynamic test shall be recorded in the test report.
              7.9. Additional tests on safety-belts with pre-loading devices
7.9.1.  Conditioning
               The pre-loading device may be separated from the safety-belt to be tested and kept for 24 hours at a temperature of 60 ± 5 °C. The temperature shall then be raised to 100 ± 5 °C for two hours. Subsequently it shall be kept for 24 hours at a temperature of -30 ± 5 °C. After being removed from conditioning, the device shall warm up to ambient temperature. If it has been separated it shall be fitted again to the safety-belt.
              7.10. Test report
              7.10.1. The test report shall record the results of all the tests in paragraph 7. above and in particular:
                  (a) The type of device used for the test (acceleration or deceleration device);
               (b) The total velocity change;
                  (c) The trolley speed immediately before impact only for deceleration trolleys;
                  (d) The acceleration or deceleration curve during all the velocity change of the trolley;
               (e) The maximum forward displacement of the manikin;
                  (f) The place – if it can be varied – occupied by the buckle during the test;
               (g) The buckle-opening force;
               (h) Any failure or breakage.
                  (i) For any restrain system other than the driver's the contour of the contact should be evaluated versus the movement of the manikin in the sled by the technical service in this report.
               If by virtue of paragraph 7.7.1. the anchorages prescribed in Annex 6 to this Regulation have not been respected, the test report shall describe how the belt assembly or the restraint system was installed and shall specify important angles and dimensions.
