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 Section 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 Guides' device within 100 mm of their design positions with the test seat datum point assumed to coincide with the test 'Searing Reference Point'; or
4.9.1.2.                        a trolley and a vehicle body shell complete with a driver's 'Seat' adjusted to the rearmost driving or riding position.
4.9.2.                              A dummy meeting the requirements of Section 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 'Seat Belt Assembly' as follows:
4.9.2.1.                        in the case of 'Seat Belt Assemblies' incorporating m retractors, the belt shall be manually adjusted around the dummy to eliminate slack; and
4.9.2.2.                        in the case of other 'Seat Belt 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.
4.10.2.                          When tested in accordance with the requirements of Section 4.11 for dummy calibration, the test dummy shall give rise to 'Seat Belt 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 10 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 10 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 Section 4.12 for test rig calibration. It shall comprise a trolley, test 'Seat', 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.
