the dynamic test procedure of clause 12.
10.2.                                Prior to the dynamic test, each 'Seatbelt Assembly' must be subjected to the preconditioning requirements of clause 10.3.
10.3.                                Dynamic Test Preconditioning
10.3.1.                          Any 'Buckle Component' or manual adjusting device which can take up a position in a door opening, or under a pivoting 'Seat', must be placed on a flat surface in its most stable position and subjected to a force of not less than 1.8 kN for a period of not less than 10 seconds.  The force must be applied through a rigid bar of diameter not more than 20 mm formed to an arc of radius not more than 150 mm, with the bar in line with the 'Strap' when viewed in plan, and the test must be repeated with the bar normal to the direction of the 'Strap' when viewed in plan.
10.3.2.                          The buckle assembly must be subjected to not less than 20,000 unlatching operations.  During each unlatching operation a tensile load of not less than 20 N must be applied to the assembly.
10.3.3.                          Each 'Seatbelt Assembly' which contains non-metallic material (other than a webbing 'Strap') must be exposed to environment over a water surface within a closed space, the environment having a temperature of not less than 80°C, for a continuous period of not less than 24 hours and then cooled in an environment having a temperature not exceeding 23°C.  The cooling period must immediately be followed by three consecutive 24 hour cycles with each cycle comprising the following consecutive sequences:
10.3.3.1.                    an environment having a temperature of not less than l00°C must be maintained for a continuous period of 6 hours and this environment must be attained within 80 minutes of commencement of the cycle; then
10.3.3.2.                    an environment having a temperature of not more than 0°C must be maintained for a continuous period of 6 hours and this environment must be attained within 20 minutes; then
10.3.3.3.                    an environment having a temperature of not more than 23°C must be maintained during the remainder of the 24 hour cycle.
11.                                      RETRACTOR DURABILITY TEST
         The 'Seatbelt Assembly' must be prepared, conditioned and tested to AS 2597.9-1983 "Preparation and Conditioning of Test Specimens for Retractor Function".
12.                                      DYNAMIC TESTING PROCEDURE
12.1.                                The test rig must have a mass of not less than 380 kg and must meet the requirements of clause 15 for test rig calibration.  It must comprise either:
12.1.1.                          a trolley and 'Seat' as specified in clauses 14.1 and 14.2 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
12.1.2.                          a
