by three consecutive 24 hour cycles with each cycle comprising the following consecutive sequences:
4.7.3.3.1.                  an environment having a temperature of not less than l00°C shall be maintained for a continuous period of 6 hours and this environment shall be attained within 80 minutes of commencement of the cycle; then
4.7.3.3.2.                  an environment having a temperature of not more than 0°C shall be maintained for a continuous period of 6 hours and this environment shall be attained within 20 minutes; then
4.7.3.3.3.                  an environment having a temperature of not more than 23°C shall be maintained during the remainder of the 24 hour cycle.
4.8.                                    RETRACTOR DURABILITY TEST
4.8.0.                              The 'Seatbelt Assembly' shall be prepared, conditioned and tested to AS 2597.9-1983 "Preparation and Conditioning of Test Specimens for Retractor Function".
4.8.1.                              Not used.
4.8.2.                              Not used.

4.9.                                    DYNAMIC TESTING PROCEDURE
4.9.1.                              The test rig shall have a mass of not less than 380 kg and shall meet the requirements of clause 4.12 for test rig calibration.  It shall comprise either:
4.9.1.1.                        a trolley and 'Seat' as specified in clauses 4.11.1 and 4.11.2 for dummy calibration, and with 'Anchorages' and 'Sash Guide' devices within l00 mm of their design positions with the test seat datum point assumed to coincide with the 'Seating Reference Point'; or
4.9.1.2.                        a trolley and a vehicle body shell complete with a  representative 'Seat' adjusted to the rearmost driving or riding position.
4.9.2.                              A dummy meeting the requirements of clause 4.10 shall be placed in the appropriate seating position so that its centre-line lies in the 'Seating Reference Plane' and such that it is restrained by the 'Seatbelt Assembly' as follows:
4.9.2.1.                        in the case of 'Seatbelt Assemblies' incorporating retractors, the belt shall be manually adjusted around the dummy to eliminate slack; and
4.9.2.2.                        in the case of other 'Seatbelt Assemblies', a spacer of flexible but substantially incompressible material not less than 25 mm thick and at least as wide and as long as the dummy's back shall be placed behind the back of the dummy.  The assembly shall be adjusted to eliminate slack and the spacer then removed.  The dummy shall be re-positioned so that its back is in contact with the 'Seat' back.
4.9.3.                              The rig shall be operated in a manner identical in all operational respects to that specified in clause 4.12.1 for rig calibration except that in this case the dummy replaces the inert mass.
4.10.                                TEST DUMMY REQUIREMENTS
4.10.1.                          The dummy shall have a mass of 74 + 2 kg.
         When tested in accordance with the requirements of clause 4.11 for dummy calibration, the test dummy shall give rise to 'Seatbelt Assembly' loads such that the sum of the peak
