75% of the 'Dry Breaking Strength', whichever is the greater, after the retracting 'Strap' has been drawn through the 'Sash Guide' system for 50,000 cycles under the following test conditions:
8.2.1.                              the tensile load in all parts of the test 'Strap' during the working stroke of the 2 strokes of each cycle must not be less than 18 N;
8.2.2.                              the tensile load in the test 'Strap' at one point in the cycle must be reduced to zero;
8.2.3.                              the working stoke must be not less than 200 mm;
8.2.4.                              the orientation of the test 'Strap' relative to the 'Sash Guide' must be such that:
8.2.4.1.                        the 'Sash Guide' must be in its design configuration except that, for 'Sash Guides' designed to pivot, the angle of the axis of rotation may vary from its design configuration provided that such variation is not greater than 5°,
8.2.4.2.                        the part of the test 'Strap' which simulates the 'Strap' passing from the 'Sash Guide' to the next 'Sash Guide' or to the retractor, must be in the design configuration; and
8.2.4.3.                        the part of the test 'Strap' which simulates the torso 'Strap' must be pulled in a vertical plane not more than 45° or a longitudinal plane when viewed in plan, and the direction of pull in that plane must vary over a range of not less than 65° during the working stroke of each cycle; and
8.2.5.                              all 'Sash Guides' for the one assembly must be tested simultaneously.
8.2.6.                              The requirements of this clause must not apply to relative movement between the 'Strap' and the retractor, at the retractor.
8.3.                                    Buckle-Spring Fatigue Resistance
8.3.1.                              In the case where a spring is incorporated in the unlatching mechanism of a buckle, the load required to operate the spring must not be reduced by more than 20% after the spring has been subjected to 50,000 operations each involving a movement not less than 95% of the design movement for buckle unlatching.
9.                                          RETRACTORS (other than 'TYPE 4N RETRACTORS')
9.1.                                    All retractors incorporated in 'Seatbelt Assemblies' must comply with the requirements of clause 9.2 and either clause 9.3 or 9.4.
9.2.                                    General Requirements for Retractors
9.2.1.                              After being subjected to the retractor durability test of clause 11, the retractor must:
9.2.1.1.                        when locked, either:
9.2.1.1.1.                  withstand a tensile load of not less than 9 kN applied to the 'Strap'; or
9.2.1.1.2.                  be subjected to the strength of assembly test of clause 14.1 of AS 2596-1983 "Seat Belt Assemblies for Motor Vehicles".
9.2.1.2.                        withstand a tensile load of not less than 9 kN applied to the 'Strap'.  For the purpose of this test the 'Strap' must be fully withdrawn and the locking mechanism must be rendered inoperative.
