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, operation of the pre-loading device shall 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 + 100 - 0 daN shall be not less than 46 mm. This dimension shall be measured according to the test prescribed in paragraph 7.4.3. below, stopping the machine at the above mentioned load.[7]
              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 of the breaking loads measured.
              6.3.3. Strength after special conditioning
               In the case of the two strap samples conditioned in conformity with one of the provisions of paragraph 7.4.1. (except 7.4.1.1.) below, the breaking load of the strap shall be not less than 75 per cent of average of the loads determined in the test referred to in paragraph 6.3.2. and not less than 1,470 daN. The Technical Service conducting the tests may dispense with one or more of these tests if the composition of the material used or information already available renders the test or tests superfluous.
              6.4. Belt assembly or restraint system
              6.4.1. Dynamic test
              6.4.1.1. The belt assembly or restraint system shall be subjected to a dynamic test in conformity with paragraph 7.7. below.
              6.4.1.2. The dynamic test shall be performed on two belt assemblies which have not previously been under load, except in the case of belt assemblies forming part of restraint systems when the dynamic test shall be performed on the restraint systems intended for one group of seats which have not previously been under load. The buckles of the belt assemblies to be tested shall have met the requirements of paragraph 6.2.2.4. above. In the case of safety-belts with retractors, the retractor shall have been subjected to
