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 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
4.10.2.                           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.
4.11.                                DUMMY CALIBRATION
4.11.1.                          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 a trolley, test 'Seat', foot  rest, and structure for providing seatbelt 'Anchorages', meeting the dimensional requirements indicated in Figure 1.
4.11.2.                          The 'Seat' base surface shall not be designed with energy absorbing characteristics and shall present a smooth surface for the dummy.
4.11.3.                          The dummy shall 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 shall be determined by the  method described in AS 1753-1975:  "Webbing for Restraining Devices for Occupants of Motor Vehicles", except that the specimen shall be loaded to 11 kN in lieu of the load specified in the Australian Standard.
4.11.4.                          The 'Lap Belts' and sash belts shall be adjusted to eliminate slack.
4.11.5.                          The rig shall be operated in a manner identical in all operational respects to that specified in clause 4.12.2 for rig calibration except that in this case the dummy replaces the inert mass.
4.12.                                TEST RIG CALIBRATION
4.12.1.                          In the case of calibration prior to seat belt testing, the test rig, to which a mass of 74 + 2 kg is rigidly attached, when subjected to a velocity change of not less than 49 km/h, shall achieve within 30 milliseconds a 'Forward' deceleration measured in the vicinity of a lap 'Anchorage' of at least 235 m/s2 and shall maintain this deceleration, except for periods of less than one millisecond, for not less than 20 milliseconds.
4.12.2.                          In the case of calibration prior to proving the dummy, the test rig, to which a mass of 74 + 2 kg is rigidly attached, when subjected to a velocity change of not less than 49 km/h, shall achieve within 30 milliseconds, a 'Forward' deceleration measured in the vicinity of a lap 'Anchorage', within the range 235 to 335 m/s2 and shall maintain this deceleration, except for periods of less
