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 trolley and a vehicle body shell complete with a representative 'Seat' adjusted to the rearmost driving or riding position.
12.2.                                A dummy meeting the requirements of clause 13 must 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:
12.2.1.                          in the case of 'Seatbelt Assemblies' incorporating retractors, the belt must be manually adjusted around the dummy to eliminate slack; and
12.2.2.                          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 must be placed behind the back of the dummy.  The assembly must be adjusted to eliminate slack and the spacer then removed.  The dummy must be re-positioned so that its back is in contact with the 'Seat' back.
12.3.                                The rig must be operated in a manner identical in all operational respects to that specified in clause 15.1 for rig calibration except that in this case the dummy replaces the inert mass.
13.                                      TEST DUMMY REQUIREMENTS
13.1.                                The dummy must have a mass of 74 ± 2 kg.
13.2.                                When tested in accordance with the requirements of clause 14 for dummy calibration, the test dummy must give rise to 'Seatbelt Assembly' loads such that the sum of the peak restraining forces in each length of the sash 'Strap' which is not in contact with the dummy is not less than l0 kN, and also that the sum of the peak restraining forces in each length of the lap 'Strap' which is not in contact with the dummy is not less than l0 kN.
14.                                      DUMMY CALIBRATION
14.1.                                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 a trolley, test 'Seat', foot rest, and structure for providing seatbelt 'Anchorages', meeting the dimensional requirements indicated in Figure 1.
14.2.                                The 'Seat' base surface must not be designed with energy absorbing characteristics and must present a smooth surface for the dummy.
14.3.                                The dummy must be restrained by separate 'Lap Belts' and sash belts, each of which comprises load bearing material having an elongation of not less than 12% when subjected to a load of 11 kN.  The method of test of elongation must be determined by the method described
