foot rest, and structure for providing seat belt '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 Appendix B of AS E47-1971 or 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 Standards.
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 respect 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 with 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 than one millisecond, for not less than 20 millisecond.
4.13.                                COMPONENT BOUNDARY LOCATION

         4.13.0 The lines shown in Figure 2 in side elevation are established as follows:

4.13.1.                          Line A is a horizontal line 850 mm above the 'Seating Reference Point';
4.13.2.                          Line B is a horizontal line 330 mm above the 'Seating Reference Point';
4.13.3.                          Line C is a horizontal line 680 mm above the `Seating Reference Point'
4.13.4.                          Line D is a horizontal line 150 mm below the `Seating Reference Point';
4.13.5.                          Line E is a horizontal line 75 mm below the 'Seating Reference Point'
4.13.6.                          Line POS consists of 2 lines PO and OS and is constructed as follows:
4.13.6.1.                    draw line PO parallel to the `Torso Reference Line' and intersecting
