the free length between the dummy and the retractor in accordance with paragraph 7.6.4.
               If the retractor is part of an upper torso restraint, the retracting force of the strap shall be not less than 0.1 daN and not more than 0.7 daN when similarly measured, except for a belt equipped with a tension-reducing device, in which case the minimum retracting force may be reduced to 0.05 daN only when such a device is in operation mode. If the strap passes through a guide or pulley, the retracting force shall be measured in the free length between the dummy and the guide or pulley.
               If the assembly incorporates a device that upon manual or automatic operation prevents the strap from being completely retracted, such a device shall not be operated when these requirements are assessed.
               If the assembly incorporates a tension-reducing device, the retracting force of the strap described in the above shall be measured with the device in operation mode and non-operation mode when these requirements are assessed before and after durability tests according to paragraph 6.2.5.3.5. below.
              6.2.5.3.5. The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1. until 40,000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2. and after that to the dust test prescribed in paragraph 7.6.3. below. It shall then satisfactorily complete a further 5,000 cycles (making 45,000 in all).
               If the assembly incorporates a tension-reducing device, the above tests shall be conducted on condition that the tension-reducing device is in operation mode and in non-operation mode.
               After the above tests, the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.3.1., 6.2.5.3.3. and 6.2.5.3.4. above.
              6.2.5.4. Retractors shall fulfill, after durability test according to paragraph 6.2.5.3.5., and immediately after the retracting force measurement according to paragraph 6.2.5.3.4. above, all next two specifications:
              6.2.5.4.1. When retractors except automatically locking retractors are tested according to paragraph 7.6.4.2. below, the retractors shall be able to avoid any slack between torso and belt, and,
              6.2.5.4.2. When the buckle is unlatched to release the tongue, the retractor alone shall be able to retract strap fully.
              6.2.6. Pre-loading device
              6.2.6.1. After being submitted to corrosion testing in accordance with paragraph 7.2. below, the pre-loading device (including the impact sensor connected to the device by the original plugs but without any current passing through them) shall operate normally.
              6.2.6.2. It shall be verified that inadvertent operation of the device does not involve any risk of bodily injury for wearer.
              6.2.6.3. In the case of pyrotechnic pre-loading devices:
              6.2.6.3.1. After being submitted to conditioning in accordance with paragraph 7.9.1. below,
