be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1.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.  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 must 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., all next two specifications:

           6.2.5.4.1. When retractors except automatically locking retractors are tested according to paragraph 7.6.4.2., the retractors must 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 must 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., 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 7.9.2., operation of the pre‑loading device must not have been activated by temperature and the device shall operate normally.

           6.2.6.3.2. Precautions shall be taken to prevent the hot gases expelled from igniting adjacent flammable materials.

6.3. Straps

           6.3.1. General

           6.3.1.1. The characteristics of the straps shall be such as to ensure that their pressure on the wearer's body is distributed as evenly as possible over their width and that they do not twist even under tension.  They shall have energy‑absorbing and energy‑dispersing capacities.  The straps shall have finished selvages which shall not become unravelled in use.

           6.3.1.2. The width of the strap under load of 980 daN shall be not less than 46 mm.  This dimension shall be measured during the breaking‑strength test prescribed in paragraph 7.4.2. and without stopping the machine.

           6.3.2. Strength after room‑conditioning

           In the case of the two straps samples conditioned in conformity with paragraph 7.4.1.1. the breaking load of the strap, determined as prescribed in paragraph 7.4.2. below, shall be not less than 1,470 daN.  The difference between the breaking loads of the two samples shall not exceed 10 per cent of the greater
