4.8.                                    RETRACTOR DURABILITY TEST

         4.8.0. The 'Seat Belt Assembly' shall be prepared, conditioned and tested to AS 2597.9-1983 'Preparation and Conditioning of Test Specimens for Retractor Function" or to Clause 4.8.1 to 4.8.3. below.

4.8.1.                              The 'Seat Belt Assembly' shall be conditioned by the procedure specified in ASTM B 117-64 'Standard Method of Salt Spray (Fog) Testing'. The period of conditioning shall be not less than 50 hours.
4.8.2.                              At the end of the conditioning procedure specified in Clause 4.8.1 the 'Seat Belt Assembly' may be washed thoroughly with water to remove the salt.  If washed, the webbing shall be fully extended and allowed to dry for a least 24 hours in an atmosphere having a relative humidity of not less than 48% nor more than 67% and a temperature of not less than 21oC or more than 25oC. The webbing shall then be withdrawn manually and allowed to retract for 25 cycles.
4.8.3.                              Following the procedure specified in Clause 4.8.2, the retractor shall be subjected to the following:
4.8.3.1.                        in the case of 'Automatic Length Adjusting and Locking Retractors'. the 'Strap' shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in Appendix A of AS E35. Pt.II - 1970 "Seat Belt Assemblies (including retractors) for motor vehicles' including amendment No. 1 for not less than 5,000 cycles after which the retractor, including the 'strap' wound upon the reel, shall be subjected to application of dust as described in Appendix C of that Australian Standard. The 'Strap' shall then be subjected to at least 5,000 cycles of withdrawal and reaction. The locking mechanism shall be functional at the completion of the test: and
4.8.3.2.                        in the case of 'Emergency Locking Retractor', the 'Strap' shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in Appendix A of Australian Standard referred to in clause 4.3.3.1 for not less than 45,000 cycles after which the retractor, including the 'Soap' wound upon the reel shall be subjected to the application of dust as described in Appendix C of that Australian Standard or the Australian Standard referred to in Clause 4.8.0. The 'Strap' shall then be subjected to at least 5,000 cycles of withdrawal and retraction.
